3 JWS Annotation Reference

Description

Target: Method

Specifies the method that handles a potential failure when the main JWS file invokes an operation of another Web Service asynchronously.

When you invoke, from within a JWS file, a Web Service operation asynchronously, the response (or exception, in the case of a failure) does not return immediately after the operation invocation, but rather, at some later point in time. Because the operation invocation did not wait for a response, a separate method in the JWS file must handle the response when it does finally return; similarly, another method must handle a potential failure. Use the @AsyncFailure annotation to specify the method in the JWS file that will handle the potential failure of an asynchronous operation invocation.

The @AsyncFailure annotation takes two parameters: the name of the stub for the Web Service you are invoking and the name of the operation that you are invoking asynchronously. The stub is the one that has been annotation with the @ServiceClient annotation.

The method that handles the asynchronous failure must follow these guidelines:

• Return void.

• Be named onMethodNameAsyncFailure, where MethodName is the name of the method you are invoking asynchronously (with initial letter always capitalized.)

  In the main JWS file, the call to the asynchronous method will look something like:

  port.getQuoteAsync (apc, symbol);
  

  where getQuote is the non-asynchronous name of the method, apc is the asynchronous pre-call context, and symbol is the usual parameter to the getQuote operation.

• Have two parameters: the asynchronous post-call context (contained in the weblogic.wsee.async.AsyncPostCallContext object) and the Throwable exception, potentially thrown by the asynchronous operation call.

Within the method itself you can get more information about the method failure from the context, and query the specific type of exception and act accordingly.

Typically, you always use the @AsyncFailure annotation to explicitly specify the method that handles asynchronous operation failures. The only time you would not use this annotation is if you want a single method to handle failures for two or more stubs that invoke different Web Services. In this case, although the stubs connect to different Web Services, each Web Service must have a similarly named method, because the Web Services runtime relies on the name of the method (onMethodNameAsyncFailure) to determine how to handle the asynchronous failure, rather than the annotation. However, if you always want a one-to-one correspondence between a stub and the method that handles an asynchronous failure from one of the operations, then Oracle recommends that you explicitly use @AsyncFailure.

See "Invoking a Web Service Using Asynchronous Request-Response" in Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server for detailed information and examples of using this annotation.

Example

The following sample snippet shows how to use the @AsyncFailure annotation in a JWS file that invokes the operation of another Web Service asynchronously; only the relevant Java code is included:

package examples.webservices.async_req_res;
...
public class StockQuoteClientImpl {
  @ServiceClient(wsdlLocation="http://localhost:7001/async/StockQuote?WSDL",
                 serviceName="StockQuoteService", portName="StockQuote")
  private StockQuotePortType port;
  @WebMethodpublic void getQuote (String symbol) {
    AsyncPreCallContext apc = AsyncCallContextFactory.getAsyncPreCallContext();
    apc.setProperty("symbol", symbol);
    try {
      port.getQuoteAsync(apc, symbol );
      System.out.println("in getQuote method of StockQuoteClient WS");
    }
    catch (RemoteException e) {
      e.printStackTrace();
    }
  }
...
  @AsyncFailure(target="port", operation="getQuote")
  public void onGetQuoteAsyncFailure(AsyncPostCallContext apc, Throwable e) {
    System.out.println("-------------------");
    e.printStackTrace();
    System.out.println("-------------------");
  }
}

The example shows a stub called port, used to invoke the Web Service located at http://localhost:7001/async/StockQuote. The getQuote operation is invoked asynchronously, and any exception from this invocation is handled by the onGetQuoteAsyncFailure method, as specified by the @AsyncFailure annotation.

Description

Target: Method

Specifies the method that handles the response when the main JWS file invokes an operation of another Web Service asynchronously.

When you invoke, from within a JWS file, a Web Service operation asynchronously, the response does not return immediately after the operation invocation, but rather, at some later point in time. Because the operation invocation did not wait for a response, a separate method in the JWS file must handle the response when it does finally return. Use the @AsyncResponse annotation to specify the method in the JWS file that will handle the response of an asynchronous operation invocation.

The @AsyncResponse annotation takes two parameters: the name of the stub for the Web Service you are invoking and the name of the operation that you are invoking asynchronously. The stub is the one that has been annotation with the @ServiceClient annotation.

The method that handles the asynchronous response must follow these guidelines:

• Return void.

• Be named onMethodNameAsyncResponse, where MethodName is the name of the method you are invoking asynchronously (with initial letter always capitalized.)

  In the main JWS file, the call to the asynchronous method will look something like:

  port.getQuoteAsync (apc, symbol);
  

  where getQuote is the non-asynchronous name of the method, apc is the asynchronous pre-call context, and symbol is the usual parameter to the getQuote operation.

• Have two parameters: the asynchronous post-call context (contained in the weblogic.wsee.async.AsyncPostCallContext object) and the usual return value of the operation.

Within the asynchronous-response method itself you add the code to handle the response. You can also get more information about the method invocation from the context.

Typically, you always use the @AsyncResponse annotation to explicitly specify the method that handles asynchronous operation responses. The only time you would not use this annotation is if you want a single method to handle the response for two or more stubs that invoke different Web Services. In this case, although the stubs connect to different Web Services, each Web Service must have a similarly named method, because the Web Services runtime relies on the name of the method (onMethodNameAsyncResponse) to determine how to handle the asynchronous response, rather than the annotation. However, if you always want a one-to-one correspondence between a stub and the method that handles an asynchronous response from one of the operations, then Oracle recommends that you explicitly use @AsyncResponse.

See "Invoking a Web Service Using Asynchronous Request-Response" in Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server for detailed information and examples of using this annotation.

Example

The following sample snippet shows how to use the @AsyncResponse annotation in a JWS file that invokes the operation of another Web Service asynchronously; only the relevant Java code is included:

package examples.webservices.async_req_res;
...
public class StockQuoteClientImpl {
  @ServiceClient(wsdlLocation="http://localhost:7001/async/StockQuote?WSDL",
                 serviceName="StockQuoteService", portName="StockQuote")
  private StockQuotePortType port;
  @WebMethodpublic void getQuote (String symbol) {
    AsyncPreCallContext apc = AsyncCallContextFactory.getAsyncPreCallContext();
    apc.setProperty("symbol", symbol);
    try {
      port.getQuoteAsync(apc, symbol );
      System.out.println("in getQuote method of StockQuoteClient WS");
    }
    catch (RemoteException e) {
      e.printStackTrace();
    }
  }
...
  @AsyncResponse(target="port", operation="getQuote")
  public void onGetQuoteAsyncResponse(AsyncPostCallContext apc, int quote) {
    System.out.println("-------------------");
    System.out.println("Got quote " + quote );
    System.out.println("-------------------");
  }
}

The example shows a stub called port, used to invoke the Web Service located at http://localhost:7001/async/StockQuote. The getQuote operation is invoked asynchronously, and the response from this invocation is handled by the onGetQuoteAsyncResponse method, as specified by the @AsyncResponse annotation.

Description

Target: Class

Specifies whether the Web Service uses version 1.1 or 1.2 of the Simple Object Access Protocol (SOAP) implementation when accepting or sending SOAP messages. By default, WebLogic Web Services use SOAP 1.1.

Attributes

value

Example

The following example shows how to specify SOAP 1.2; only the relevant code is shown:

package examples.webservices.soap12;
...
import javax.jws.WebMethod;
import javax.jws.WebService;
import weblogic.jws.Binding;
@WebService(name="SOAP12PortType",
            serviceName="SOAP12Service",
            targetNamespace="http://example.org")
@Binding(Binding.Type.SOAP12)
public class SOAP12Impl {
  @WebMethod()
  public String sayHello(String message) {
...
  }
}

Description

Target: Class

Specifies the JNDI name of the JMS queue to which WebLogic Server stores:

• Buffered Web Service operation invocation.

• Reliable Web Service operation invocation.

When used with buffered Web Services, you use this annotation in conjunction with @MessageBuffer, which specifies the methods of a JWS that are buffered. When used with reliable Web Services, you use this annotation in conjunction with @Policy, which specifies the reliable messaging WS-Policy file associated with the Web Service.

If you have enabled buffering or reliable messaging for a Web Service, but do not specify the @BuffereQueue annotation, WebLogic Server uses the default Web Services JMS queue (weblogic.wsee.DefaultQueue) to store buffered or reliable operation invocations. This JMS queue is also the default queue for the JMS transport features. It is assumed that you have already created this JMS queue if you intend on using it for any of these features.

See "Creating Buffered Web Services" and "Using Web Services Reliable Messaging" in Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server for detailed information and examples of creating buffered or reliable Web Services.

Attributes

name

Example

The following example shows a code snippet from a JWS file in which the public operation is buffered and the JMS queue to which WebLogic Server queues the operation invocation is called my.buffere.queue; only the relevant Java code is shown:

package examples.webservices.buffered;
...
@WebService(name="BufferedPortType",
            serviceName="BufferedService",
            targetNamespace="http://example.org")
@BufferQueue(name="my.buffer.queue")
public class BufferedImpl {
...
  @WebMethod()
  @MessageBuffer(retryCount=10, retryDelay="10 seconds")
  @Oneway()
  public void sayHelloNoReturn(String message) {
    System.out.println("sayHelloNoReturn: " + message);
  }
}

Description

Target: Field

Specifies that the annotated variable is a callback, which means that you can use the variable to send callback events back to the client Web Service that invoked an operation of the target Web Service.

You specify the @Callback annotation in the target Web Service so that it can call back to the client Web Service. The data type of the annotated variable is the callback interface.

The callback feature works between two WebLogic Web Services. When you program the feature, however, you create the following three Java files:

• Callback interface: Java interface file that defines the callback methods. You do not explicitly implement this file yourself; rather, the jwsc Ant task automatically generates an implementation of the interface. The implementation simply passes a message from the target Web Service back to the client Web Service. The generated Web Service is deployed to the same WebLogic Server that hosts the client Web Service.

• JWS file that implements the target Web Service: The target Web Service includes one or more standard operations that invoke a method defined in the callback interface; this method in turn sends a message back to the client Web Service that originally invoked the operation of the target Web Service.

• JWS file that implements the client Web Service: The client Web Service invokes an operation of the target Web Service. This Web Service includes one or more methods that specify what the client should do when it receives a callback message back from the target Web Service via a callback method.

See "Using Callbacks to Notify Clients of Events" in Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server for additional overview and procedural information about programming callbacks.

The @Callback annotation does not have any attributes.

Example

The following example shows a very simple target Web Service in which a variable called callback is annotated with the @Callback annotation. The data type of the variable is CallbackInterface; this means a callback Web Service must exist with this name. After the variable is injected with the callback information, you can invoke the callback methods defined in CallbackInterface; in the example, the callback method is callbackOperation().

The text in bold shows the relevant code:

package examples.webservices.callback;
import weblogic.jws.WLHttpTransport;
import weblogic.jws.Callback;
import javax.jws.WebService;
import javax.jws.WebMethod;
@WebService(name="CallbackPortType",
            serviceName="TargetService",
            targetNamespace="http://examples.org/")
@WLHttpTransport(contextPath="callback",
                 serviceUri="TargetService",
                 portName="TargetServicePort")
public class TargetServiceImpl {
  @Callback
  CallbackInterface callback;
  @WebMethod
  public void targetOperation (String message) {
        callback.callbackOperation (message);
  }
}

Description

Target: Method

Specifies the method in the client Web Service that handles the messages it receives from the callback Web Service. Use the attributes to link the callback message handler methods in the client Web Service with the callback method in the callback interface.

The callback feature works between two WebLogic Web Services. When you program the feature, however, you create the following three Java files:

• Callback interface: Java interface file that defines the callback methods. You do not explicitly implement this file yourself; rather, the jwsc Ant task automatically generates an implementation of the interface. The implementation simply passes a message from the target Web Service back to the client Web Service. The generated Web Service is deployed to the same WebLogic Server that hosts the client Web Service.

• JWS file that implements the target Web Service: The target Web Service includes one or more standard operations that invoke a method defined in the callback interface; this method in turn sends a message back to the client Web Service that originally invoked the operation of the target Web Service.

• JWS file that implements the client Web Service: The client Web Service invokes an operation of the target Web Service. This Web Service includes one or more methods that specify what the client should do when it receives a callback message back from the target Web Service via a callback method.

See "Using Callbacks to Notify Clients of Events" in Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server for additional overview and procedural information about programming callbacks.

Attributes

target

Example

The following example shows a method of a client Web Service annotated with the @CallbackMethod annotation. The attributes show that a variable called port must have previously been injected with stub information and that the annotated method will handle messages received from a callback operation called callbackOperation().

  @CallbackMethod(target="port", operation="callbackOperation")
  @CallbackRolesAllowed(@SecurityRole(role="engineer",  mapToPrincipals="shackell"))
  public void callbackHandler(String msg) {
        System.out.println (msg);
  }

Description

Target: Class

Specifies that the JWS file is actually a Java interface that describes a callback Web Service. This annotation is analogous to the @javax.jws.WebService, but specific to callbacks and with a reduced set of attributes.

The callback feature works between two WebLogic Web Services. When you program the feature, however, you create the following three Java files:

• Callback interface: Java interface file that defines the callback methods. You do not explicitly implement this file yourself; rather, the jwsc Ant task automatically generates an implementation of the interface. The implementation simply passes a message from the target Web Service back to the client Web Service. The generated Web Service is deployed to the same WebLogic Server that hosts the client Web Service.

• JWS file that implements the target Web Service: The target Web Service includes one or more standard operations that invoke a method defined in the callback interface; this method in turn sends a message back to the client Web Service that originally invoked the operation of the target Web Service.

• JWS file that implements the client Web Service: The client Web Service invokes an operation of the target Web Service. This Web Service includes one or more methods that specify what the client should do when it receives a callback message back from the target Web Service via a callback method.

Use the @CallbackInterface annotation to specify that the Java file is a callback interface file.

When you program the callback interface, you specify one or more callback methods; as with standard non-callback Web Services, you annotate these methods with the @javax.jws.WebMethod annotation to specify that they are Web Service operations. However, contrary to non-callback methods, you never write the actual implementation code for these callback methods; rather, when you compile the client Web Service with the jwsc Ant task, the task automatically creates an implementation of the interface and packages it into a Web Service. This generated implementation specifies that the callback methods all do the same thing: send a message from the target Web Service that invokes the callback method back to the client Web Service.

See "Using Callbacks to Notify Clients of Events" in Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server for additional overview and procedural information about programming callbacks.

Attributes

name

serviceName

Example

The following example shows a very simple callback interface. The resulting callback Web Service has one callback method, callbackOperation().

package examples.webservices.callback;
import weblogic.jws.CallbackService;
import javax.jws.Oneway;
import javax.jws.WebMethod;
@CallbackService
public interface CallbackInterface {
  @WebMethod
  @Oneway
  public void callbackOperation (String msg);
}

Description

Target: Field

Specifies that the annotated field provides access to the runtime context of the Web Service.

When a client application invokes a WebLogic Web Service that was implemented with a JWS file, WebLogic Server automatically creates a context that the Web Service can use to access, and sometimes change, runtime information about the service. Much of this information is related to conversations, such as whether the current conversation is finished, the current values of the conversational properties, changing conversational properties at runtime, and so on. Some of the information accessible via the context is more generic, such as the protocol that was used to invoke the Web Service (HTTP/S or JMS), the SOAP headers that were in the SOAP message request, and so on. The data type of the annotation field must be weblogic.wsee.jws.JwsContext, which is a WebLogic Web Service API that includes methods to query the context.

For additional information about using this annotation, see "Accessing Runtime Information about a Web Service" in Getting Started With JAX-WS Web Services for Oracle WebLogic Server.

This annotation does not have any attributes.

Example

The following snippet of a JWS file shows how to use the @Context annotation; only parts of the file are shown, with relevant code in bold:

...
import weblogic.jws.Context;
import weblogic.wsee.jws.JwsContext;

...
public class JwsContextImpl {
  @Context
  private JwsContext ctx;
  @WebMethod()
  public String getProtocol() {
...

Description

Target: Method

Specifies that a method annotated with the @Conversation annotation can be invoked as part of a conversation between two WebLogic Web Services or a stand-alone Java client and a conversational Web Service.

The conversational Web Service typically specifies three methods, each annotated with the @Conversation annotation that correspond to the start, continue, and finish phases of a conversation. Use the @Conversational annotation to specify, at the class level, that a Web Service is conversational and to configure properties of the conversation, such as the maximum idle time.

If the conversation is between two Web Services, the client service uses the @ServiceClient annotation to specify the wsdl, service name, and port of the invoked conversational service. In both the service and stand-alone client cases, the client then invokes the start, continue, and finish methods in the appropriate order to conduct a conversation.The only additional requirement to make a Web Service conversational is that it implement java.io.Serializable.

See "Creating Conversational Web Services" in Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server for detailed information and examples of using this annotation.

Attributes

value

Example

The following sample snippet shows a JWS file that contains three methods, start, middle, and finish) that are annotated with the @Conversation annotation to specify the start, continue, and finish phases, respectively, of a conversation.

...
public class ConversationalServiceImpl implements Serializable {
  @WebMethod
  @Conversation (Conversation.Phase.START)
  public String start() {
    // Java code for starting a conversation goes here
  }
  @WebMethod
  @Conversation (Conversation.Phase.CONTINUE)
  public String middle(String message) {
    // Java code for continuing a conversation goes here
  }
  @WebMethod
  @Conversation (Conversation.Phase.FINISH)
  public String finish(String message ) {
    // Java code for finishing a conversation goes here
  }
}

Description

Target: Class

Specifies that a JWS file implements a conversational Web Service.

You are not required to use this annotation to specify that a Web Service is conversational; by simply annotating a single method with the @Conversation annotation, all the methods of the JWS file are automatically tagged as conversational. Use the class-level @Conversational annotation only if you want to change some of the conversational behavior or if you want to clearly show at the class level that the JWS if conversational.

If you do use the @Conversational annotation in your JWS file, you can specify it without any attributes if their default values suit your needs. However, if you want to change values such as the maximum amount of time that a conversation can remain idle, the maximum age of a conversation, and so on, specify the appropriate attribute.

See "Creating Conversational Web Services" in Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server for detailed information and examples of using this annotation.

Attributes

maxIdleTime

@Conversational(maxIdleTime="10 minutes")

maxAge

@Conversational(maxAge="3 days")

runAsStartUser

singlePrincipal

Example

The following sample snippet shows how to specify that a JWS file implements a conversational Web Service. The maximum amount of time the conversation can be idle is ten minutes, and the maximum age of the conversation, regardless of activity, is one day. The continue and finish phases of the conversation can be executed by a user other than the one that started the conversation; if this happens, then the corresponding methods are run as the new user, not the original user.

package examples.webservices.conversation;
...
@Conversational(maxIdleTime="10 minutes",
                maxAge="1 day",
                runAsStartUser=false,
                singlePrincipal=false )
public class ConversationalServiceImpl implements Serializable {
...

Description

Target: Class

Specifies that the Web Service does not use the default WebLogic Server default filestore to store internal state information, such as conversational state, but rather uses one specified by the programmer. If you do not specify this JWS annotation in your JWS file, the Web Service uses the default filestore configured for WebLogic Server.

You can also use this JWS annotation for reliable Web Services to store internal state.

If you deploy the Web Service in a cluster, be sure you specify the logical name of the filestore so that the same name of the filestore can be used on all servers in the cluster.

Attributes

storeName

Description

Target: Class, Method

Specifies which public methods of a JWS are buffered. If specified at the class-level, then all public methods are buffered; if you want only a subset of the methods to be buffered, specify the annotation at the appropriate method-level.

When a client Web Service invokes a buffered operation of a different WebLogic Web Service, WebLogic Server (hosting the invoked Web Service) puts the invoke message on a JMS queue and the actual invoke is dealt with later on when the WebLogic Server delivers the message from the top of the JMS queue to the Web Service implementation. The client does not need to wait for a response, but rather, continues on with its execution. For this reason, buffered operations (without any additional asynchronous features) can only return void and must be marked with the @Oneway annotation. If you want to buffer an operation that returns a value, you must use asynchronous request-response from the invoking client Web Service. See "Invoking a Web Service Using Asynchronous Request-Response" in Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server for more information.

Buffering works only between two Web Services in which one invokes the buffered operations of the other.

Use the optional attributes of @MessageBuffer to specify the number of times the JMS queue attempts to invoke the buffered Web Service operation until it is invoked successfully, and the amount of time between attempts.

Use the optional class-level @BufferQueue annotation to specify the JMS queue to which the invoke messages are queued. If you do not specify this annotation, the messages are queued to the default Web Service queue, weblogic.wsee.DefaultQueue.

See "Creating Buffered Web Services" in Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server for detailed information and examples for using this annotation.

Attributes

retryCount

retryDelay

@MessageBuffer(retryDelay="2 days")

Example

The following example shows a code snippet from a JWS file in which the public operation sayHelloNoReturn is buffered and the JMS queue to which WebLogic Server queues the operation invocation is called my.buffere.queue. The WebLogic Server instance that hosts the invoked Web Service tries a maximum of 10 times to deliver the invoke message from the JMS queue to the Web Service implementation, waiting 10 seconds between each retry. Only the relevant Java code is shown in the following snippet:

package examples.webservices.buffered;
...
@WebService(name="BufferedPortType",
            serviceName="BufferedService",
            targetNamespace="http://example.org")
@BufferQueue(name="my.buffer.queue")
public class BufferedImpl {
...
  @WebMethod()
  @MessageBuffer(retryCount=10, retryDelay="10 seconds")
  @Oneway()
  public void sayHelloNoReturn(String message) {
    System.out.println("sayHelloNoReturn: " + message);
  }
}

Description

Target: Class, Method

Specifies an array of @weblogic.jws.Policy annotations.

Use this annotation if you want to attach more than one WS-Policy files to a class or method of a JWS file. If you want to attach just one WS-Policy file, you can use the @weblogic.jws.Policy on its own.

See "Using Web Services Reliable Messaging" in Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server and "Configuring Message-Level Security" in Securing WebLogic Web Services for Oracle WebLogic Server for detailed information and examples of using this annotation.

This JWS annotation does not have any attributes.

Example

@Policies({
    @Policy(uri="policy:firstPolicy.xml"),
    @Policy(uri="policy:secondPolicy.xml")
  })

Description

Target: Class, Method

Specifies that a WS-Policy file, which contains information about digital signatures, encryption, or Web Service reliable messaging, should be applied to the request or response SOAP messages.

This annotation can be used on its own to apply a single WS-Policy file to a class or method. If you want to apply more than one WS-Policy file to a class or method, use the @weblogic.jws.Policies annotation to group them together.

If this annotation is specified at the class level, the indicated WS-Policy file or files are applied to every public operation of the Web Service. If the annotation is specified at the method level, then only the corresponding operation will have the WS-Policy file applied.

By default, WS-Policy files are applied to both the request (inbound) and response (outbound) SOAP messages. You can change this default behavior with the direction attribute.

Also by default, the specified WS-Policy file is attached to the generated and published WSDL file of the Web Service so that consumers can view all the WS-Policy requirements of the Web Service. Use the attachToWsdl attribute to change this default behavior.

See "Using Web Services Reliable Messaging" in Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server and "Configuring Message-Level Security" in Securing WebLogic Web Services for Oracle WebLogic Server for detailed information and examples of using this annotation.

Example

@Policy(uri="policy:myPolicy.xml", 
          attachToWsdl=true, 
          direction=Policy.Direction.outbound)

Description

Target: Method

Specifies reliable messaging properties for an operation of a reliable Web Service, such as the number of times WebLogic Server should attempt to deliver the message from the JMS queue to the Web Service implementation, and the amount of time that the server should wait in between retries.

See "Using Web Services Reliable Messaging" in Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server for detailed information about enabling Web Services reliable messaging for your Web Service.

Attributes

retryCount

retryDelay

@ReliabilityBuffer(retryDelay="2 days")

Example

The following sample snippet shows how to use the @ReliabilityBuffer annotation at the method-level to change the default retry count and delay of a reliable operation; only relevant Java code is shown:

package examples.webservices.reliable;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.Oneway;

...
import weblogic.jws.ReliabilityBuffer;
import weblogic.jws.Policy;
@WebService(name="ReliableHelloWorldPortType",
              serviceName="ReliableHelloWorldService")

...
@Policy(uri="ReliableHelloWorldPolicy.xml",
          direction=Policy.Direction.inbound,
          attachToWsdl=true)
public class ReliableHelloWorldImpl {
  @WebMethod()
  @Oneway()
  @ReliabilityBuffer(retryCount=10, retryDelay="10 seconds")
  public void helloWorld(String input) {
    System.out.println(" Hello World " + input);
  }
}

Description

Target: Method

Specifies the method that handles the error that results when a client Web Service invokes a reliable Web Service, but the client does not receive an acknowledgement that the reliable Web Service actually received the message.

This annotation is relevant only when you implement the Web Service reliable messaging feature; you specify the annotation in the client-side Web Service that invokes a reliable Web Service.

The method you annotate with the @ReliabilityErrorHandler annotation takes a single parameter of data type weblogic.wsee.reliability.ReliabilityErrorContext. You can use this context to get more information about the cause of the error, such as the operation that caused it, the target Web Service, the fault, and so on. The method must return void.

The single attribute of the @ReliabilityErrorHandler annotation specifies the variable into which you have previously injected the stub information of the reliable Web Service that the client Web Service is invoking; you inject this information in a variable using the @weblogic.jws.ServiceClient annotation.

Attributes

    String operation = ctx.getOperationName();
    System.out.println("Reliable operation " + operation + " may have not invoked. The error message is " + message);
  }
}

In the example, the port variable has been injected with the stub that corresponds to the ReliableHelloWorldService Web Service, and it is assumed that at some point in the client Web Service an operation of this stub is invoked. Because the onReliableMessageDeliveryError method is annotated with the @ReliabilityErrorHandler annotation and is linked with the port stub, the method is invoked if there is a failure in an invoke of the reliable Web Service. The reliable error handling method uses the ReliabilityErrorContext object to get more details about the cause of the failure.

Description

Target: Field

Specifies that the annotated variable in the JWS file is a stub used to invoke another WebLogic Web Service when using the following features:

• Web Service reliable messaging

• Asynchronous request-response

• Conversations

You use the reliable messaging and asynchronous request-response features only between two Web Services; this means, for example, that you can invoke a reliable Web Service operation only from within another Web Service, not from a stand-alone client. In the case of reliable messaging, the feature works between any two application servers that implement the WS-ReliableMessaging specification at http://docs.oasis-open.org/ws-rx/wsrm/200702/wsrm-1.1-spec-os-01.pdf. In the case of asynchronous request-response, the feature works only between two WebLogic Server instances.

You use the @ServiceClient annotation in the client Web Service to specify which variable is a port type for the Web Service described by the @ServiceClient attributes. The Enterprise Application that contains the client Web Service must also include the stubs of the Web Service you are invoking; you generate the stubs with the clientgen Ant task.

See Programming Advanced Features of JAX-RPC Web Services for Oracle WebLogic Server for additional information and examples of using the @ServiceClient annotation.

Attributes

serviceName

portName

wsdlLocation

endpointAddress

Example

The following JWS file excerpt shows how to use the @ServiceClient annotation in a client Web Service to annotate a field (port) with the stubs of the Web Service being invoked (called ReliableHelloWorldService whose WSDL is at the URL http://localhost:7001/ReliableHelloWorld/ReliableHelloWorld?WSDL); only relevant parts of the example are shown:

package examples.webservices.reliable;
import javax.jws.WebService;
...
import weblogic.jws.ServiceClient;
import examples.webservices.reliable.ReliableHelloWorldPortType;
@WebService(...
public class ReliableClientImpl
{
  @ServiceClient(
     wsdlLocation="http://localhost:7001/ReliableHelloWorld/ReliableHelloWorld?WSDL",
     serviceName="ReliableHelloWorldService",
     portName="ReliableHelloWorldServicePort")
  private ReliableHelloWorldPortType port;
  @WebMethod
  public void callHelloWorld(String input, String serviceUrl)
     throws RemoteException {
    port.helloWorld(input);
    System.out.println(" Invoked the ReliableHelloWorld.helloWorld operation reliably." );
  }
}

Description

Target: Class

Specifies that the WebLogic Web Services runtime use streaming APIs when reading the parameters of all methods of the Web Service. This increases the performance of Web Service operation invocation, in particular when the parameters are large, such as images.

You cannot use this annotation if you are also using the following features in the same Web Service:

• Conversations

• Reliable Messaging

• JMS Transport

• A proxy server between the client application and the Web Service it invokes

The @StreamAttachments annotation does not have any attributes.

Example

The following simple JWS file shows how to specify the @StreamAttachments annotation; the single method, echoAttachment(), simply takes a DataHandler parameter and echoes it back to the client application that invoked the Web Service operation. The WebLogic Web Services runtime uses streaming when reading the DataHandler content.

package examples.webservices.stream_attach;
import javax.jws.WebMethod;
import javax.jws.WebService;
import weblogic.jws.WLHttpTransport;
import weblogic.jws.StreamAttachments;
import javax.activation.DataHandler;
import java.rmi.RemoteException;
@WebService(name="StreamAttachPortType",
            serviceName="StreamAttachService",
            targetNamespace="http://example.org")
@WLHttpTransport(contextPath="stream_attach",
                 serviceUri="StreamAttachService",
                 portName="StreamAttachServicePort")
@StreamAttachments
/**
 * Example of stream attachments
 */
public class StreamAttachImpl {
  @WebMethod()
  public DataHandler echoAttachment(DataHandler dh) throws RemoteException {
        return dh;
  }
}

Description

Target: Class, Method

Specifies whether the annotated operation, or all the operations of the JWS file when the annotation is specified at the class-level, runs or run inside of a transaction. By default, the operations do not run inside of a transaction.

Attributes

value

timeout

Example

The following example shows how to use the @Transactional annotation to specify that an operation of a Web Service executes as part of a transaction:

package examples.webservices.transactional;
import javax.jws.WebMethod;
import javax.jws.WebService;
import weblogic.jws.WLHttpTransport;
import weblogic.jws.Transactional;
@WebService(name="TransactionPojoPortType",
            serviceName="TransactionPojoService",
            targetNamespace="http://example.org")
@WLHttpTransport(contextPath="transactionsPojo",
                 serviceUri="TransactionPojoService",
                 portName="TransactionPojoPort")
/**
 * This JWS file forms the basis of simple WebLogic
 * Web Service with a single operation: sayHello.  The operation executes
 * as part of a transaction.
*/
public class TransactionPojoImpl {
  @WebMethod()
  @Transactional(value=true)
  public String sayHello(String message) {
    System.out.println("sayHello:" + message);
    return "Here is the message: '" + message + "'";
  }
}

Description

Target: Method, Parameter

Specifies a comma-separated list of fully qualified Java class names of the alternative data types for a return type or parameter. The alternative data types must extend the data type specified in the method signature; if this is not the case, the jwsc Ant task returns a validation error when you compile the JWS file into a Web Service.

For example, assume you have created the Address base data type, and then created USAAddress and CAAddress that extend this base type. If the method signature specifies that it takes an Address parameter, you can annotate the parameter with the @Types annotation to specify that the public operation also takes USAAddress and CAAddress as a parameter, in addition to the base Address data type.

You can also use this annotation to restrict the data types that can be contained in parameters or return values of collection data types, such as java.util.Collection or java.util.List. By restricting the allowed contained data types, the generated WSDL is specific and unambiguous, and the Web Services runtime can do a better job of qualifying the parameters when a client application invokes a Web Service operation.

If you specify this annotation at the method-level, then it applies only to the return value. If you want the annotation to apply to parameters, you must specify it at the parameter-level for each relevant parameter.

Attributes

value

Example

The following example shows a simple JWS file that uses the @Types annotation, with relevant Java code shown in bold:

package examples.webservices.types;
import javax.jws.WebMethod;
import javax.jws.WebService;
import weblogic.jws.WLHttpTransport;
import weblogic.jws.Types;
import examples.webservices.types.BasicStruct;
@WebService(serviceName="TypesService",
            name="TypesPortType",
            targetNamespace="http://example.org")
@WLHttpTransport(contextPath="types",
                 serviceUri="TypesService",
                 portName="TypesServicePort")
public class TypesImpl {
  @WebMethod()
  @Types({"examples.webservices.types.ExtendedStruct"})
  public BasicStruct echoStruct(
     @Types({"examples.webservices.types.ExtendedStruct"}) BasicStruct struct)
  {
    System.out.println("echoStruct called");
    return struct;
  }
}

In the example, the signature of the echoStruct() method shows that it takes a BasicStruct value as both a parameter and a return value. However, because both the method and the struct parameter are annotated with the @Types annotation, a client application invoking the echoStruct operation can also pass it a parameter of data type ExtendedStruct; in this case the operation also returns an ExtendedStruct value. It is assumed that ExtendedStruct extends BasicStruct.

Description

Target: Class

Specifies the XML Schema data type to which a wildcard class, such as javax.xml.soap.SOAPElement or org.apache.xmlbeans.XmlObject, binds. By default, these Java data types bind to the <xsd:any> XML Schema data type. By using this class-level annotation, you can specify that the wildcard classes bind to <xsd:anyType> instead.

Attributes

className

binding

Example

The following example shows how to use the @WildcardBinding annotation to specify that the Apache XMLBeans data type XMLObject should bind to the <xsd:any> XML Schema data type for this Web Service:

@WildcardBindings({
    @WildcardBinding(className="org.apache.xmlbeans.XmlObject", 
                      binding=WildcardParticle.ANY),
    @WildcardBinding(className="org.apache.xmlbeans.XmlObject[]",
                      binding=WildcardParticle.ANY)})
public class SimpleImpl {
...

Description

Target: Class

Specifies an array of @weblogic.jws.WildcardBinding annotations.

This JWS annotation does not have any attributes.

See weblogic.jws.WildcardBinding for an example.

Description

Target: Class

Specifies the context path and service URI sections of the URL used to invoke the Web Service over the HTTP transport, as well as the name of the port in the generated WSDL.

You can specify this annotation only once (maximum) in a JWS file.

Attributes

contextPath

http://hostname:7001/financial/GetQuote?WSDL

serviceUri

http://hostname:7001/financial/GetQuote?WSDL

portName

Example

@WLHttpTransport(contextPath="complex", 
                 serviceUri="ComplexService",
                 portName="ComplexServicePort")

Description

Target: Class

Specifies the context path and service URI sections of the URL used to invoke the Web Service over the HTTPS transport, as well as the name of the port in the generated WSDL.

You can specify this annotation only once (maximum) in a JWS file.

Attributes

contextPath

https://hostname:7001/financial/GetQuote?WSDL

serviceUri

https://hostname:7001/financial/GetQuote?WSDL

portName

Example

@WLHttpsTransport(portName="helloSecurePort",
                 contextPath="secure",
                 serviceUri="SimpleSecureBean")

Description

Target: Class

Specifies the context path and service URI sections of the URL used to invoke the Web Service over the JMS transport, as well as the name of the port in the generated WSDL. You also use this annotation to specify the JMS queue to which WebLogic Server queues the SOAP request messages from invokes of the operations.

You can specify this annotation only once (maximum) in a JWS file.

Attributes

contextPath

serviceUri

queue

portName

connectionFactory

Example

The following example shows how to specify that the JWS file implements a Web Service that is invoked using the JMS transport. The JMS queue to which WebLogic Server queues SOAP message requests from invokes of the service operations is JMSTransportQueue; it is assumed that this JMS queue has already been configured for WebLogic Server.

WLJmsTransport(contextPath="transports", 
                serviceUri="JMSTransport",
                queue="JMSTransportQueue", 
                portName="JMSTransportServicePort")

Description

Target: Class

Specifies whether to expose the WSDL of a deployed WebLogic Web Service.

By default, the WSDL is exposed at the following URL:

http://[host]:[port]/[contextPath]/[serviceUri]?WSDL

where:

• host refers to the computer on which WebLogic Server is running.

• port refers to the port number on which WebLogic Server is listening (default value is 7001).

• contextPath and serviceUri refer to the value of the contextPath and serviceUri attributes, respectively, of the @WLHttpTransport JWS annotation of the JWS file that implements your Web Service.

For example, assume you used the following @WLHttpTransport annotation:

@WLHttpTransport(portName="helloPort",
                 contextPath="hello",
                 serviceUri="SimpleImpl")

The URL to get view the WSDL of the Web Service, assuming the service is running on a host called ariel at the default port number, is:

http://ariel:7001/hello/SimpleImpl?WSDL

Attributes

exposed

Example

The following use of the @WSDL annotation shows how to specify that the WSDL of a deployed Web Service not be exposed; only relevant Java code is shown:

package examples.webservices;
import weblogic.jws.WSDL;
@WebService(name="WsdlAnnotationPortType",
            serviceName="WsdlAnnotationService",
            targetNamespace="http://example.org")
@WSDL(exposed=false)
public class WsdlAnnotationImpl {
...
}

Description

Target: Method, Field

Specifies an array of @SecurityRole JWS annotations that list the roles that are allowed to invoke the callback methods of the Web Service. A user that is mapped to an unspecified role, or is not mapped to any role at all, would not be allowed to invoke the callback methods.

If you use this annotation at the field level, then the specified roles are allowed to invoke all callback operations of the Web Service. If you use this annotation at the method-level, then the specified roles are allowed to invoke only that callback method. If specified at both levels, the method value overrides the field value if there is a conflict.

Attributes

value

Example

The following example shows how to use the @CallbackRolesAllowed annotation at the method level to specify that the role engineer is allowed to invoke the callback method:

@CallbackMethod(target="port", operation="callbackOperation")
@CallbackRolesAllowed(@SecurityRole(role="engineer", mapToPrincipals="shackell"))
public void callbackHandler(String msg) {
      System.out.println (msg);
}

Description

Target: Class, Method

Specifies whether to enable basic authentication for a Web Service. In particular, it specifies an array of @SecurityRole JWS annotations that describe the list of roles that are allowed to invoke the Web Service. A user that is mapped to an unspecified role, or is not mapped to any role at all, would not be allowed to invoke the Web Service.

If you use this annotation at the class-level, then the specified roles are allowed to invoke all operations of the Web Service. To specify roles for just a specific set of operations, specify the annotation at the operation-level.

Attributes

value

Example

package examples.webservices.security_roles;
...
import weblogic.jws.security.RolesAllowed;
import weblogic.jws.security.SecurityRole;
@WebService(name="SecurityRolesPortType",
            serviceName="SecurityRolesService",
            targetNamespace="http://example.org")
@RolesAllowed (  {
    @SecurityRole (role="manager",
                   mapToPrincipals={ "juliet","amanda" }),
    @SecurityRole (role="vp")
} )
public class SecurityRolesImpl {
...

In the example, only the roles manager and vp are allowed to invoke the Web Service. Within the context of the Web Service, the users juliet and amanda are assigned the role manager. The role vp, however, does not include a mapToPrincipals attribute, which implies that users have been mapped to this role externally. It is assumed that you have already added the two users (juliet and amanda) to the WebLogic Server security realm.

Description

Target: Class

Specifies the list of role names that reference actual roles that are allowed to invoke the Web Service. In particular, it specifies an array of @SecurityRoleRef JWS annotations, each of which describe a link between a referenced role name and an actual role defined by a @SecurityRole annotation.

This JWS annotation does not have any attributes.

Example

package examples.webservices.security_roles;
...
import weblogic.jws.security.RolesAllowed;
import weblogic.jws.security.SecurityRole;
import weblogic.jws.security.RolesReferenced;
import weblogic.jws.security.SecurityRoleRef;
@WebService(name="SecurityRolesPortType",
            serviceName="SecurityRolesService",
            targetNamespace="http://example.org")
@RolesAllowed (  {
    @SecurityRole (role="manager",
                   mapToPrincipals={ "juliet","amanda" }),
    @SecurityRole (role="vp")
} )
@RolesReferenced (
    @SecurityRoleRef (role="mgr", link="manager")
)
public class SecurityRolesImpl {
...

In the example, the role mgr is linked to the role manager, which is allowed to invoke the Web Service. This means that any user who is assigned to the role of mgr is also allowed to invoke the Web Service.

Description

Target: Class

Specifies the role and user identity which actually runs the Web Service in WebLogic Server.

For example, assume that the @RunAs annotation specifies the roleA role and userA principal. This means that even if the Web Service is invoked by userB (mapped to roleB), the relevant operation is actually executed internal as userA.

Attributes

role

mapToPrincipal

Example

package examples.webservices.security_roles;
import weblogic.jws.security.RunAs;
...
@WebService(name="SecurityRunAsPortType",
            serviceName="SecurityRunAsService",
            targetNamespace="http://example.org")
@RunAs (role="manager", mapToPrincipal="juliet")
public class SecurityRunAsImpl {
...

The example shows how to specify that the Web Service is always run as user juliet, mapped to the role manager, regardless of who actually invoked the Web Service.

Description

Target: Class, Method

Specifies the name of a role that is allowed to invoke the Web Service. This annotation is always specified in the JWS file as a member of a @RolesAllowed array.

When a client application invokes the secured Web Service, it specifies a user and password as part of its basic authentication. It is assumed that an administrator has already configured the user as a valid WebLogic Server user using the Administration Console; for details see "Create Users" in the Oracle WebLogic Server Administration Console Help.

The user that is going to invoke the Web Service must also be mapped to the relevant role. You can perform this task in one of the following two ways:

• Use the Administration Console to map the user to the role. In this case, you do not specify the mapToPrincipals attribute of the @SecurityRole annotation. For details, see "Add Users to Roles" in the Oracle WebLogic Server Administration Console Help.

• Map the user to a role only within the context of the Web Service by using the mapToPrincipals attribute to specify one or more users.

To specify that multiple roles are allowed to invoke the Web Service, include multiple @SecurityRole annotations within the @RolesAllowed annotation.

Attributes

role

mapToPrincipals

Example

package examples.webservices.security_roles;
...
import weblogic.jws.security.RolesAllowed;
import weblogic.jws.security.SecurityRole;
@WebService(name="SecurityRolesPortType",
            serviceName="SecurityRolesService",
            targetNamespace="http://example.org")
@RolesAllowed (  {
    @SecurityRole (role="manager",
                   mapToPrincipals={ "juliet","amanda" }),
    @SecurityRole (role="vp")
} )
public class SecurityRolesImpl {
...

In the example, only the roles manager and vp are allowed to invoke the Web Service. Within the context of the Web Service, the users juliet and amanda are assigned the role manager. The role vp, however, does not include a mapToPrincipals attribute, which implies that users have been mapped to this role externally. It is assumed that you have already added the two users (juliet and amanda) to the WebLogic Server security realm.

Description

Target: Class

Specifies a role name reference that links to an already-specified role that is allowed to invoke the Web Service.

Users that are mapped to the role reference can invoke the Web Service as long as the referenced role is specified in the @RolesAllowed annotation of the Web Service.

Attributes

role

link

Example

package examples.webservices.security_roles;
...
import weblogic.jws.security.RolesAllowed;
import weblogic.jws.security.SecurityRole;
import weblogic.jws.security.RolesReferenced;
import weblogic.jws.security.SecurityRoleRef;
@WebService(name="SecurityRolesPortType",
            serviceName="SecurityRolesService",
            targetNamespace="http://example.org")
@RolesAllowed (  {
    @SecurityRole (role="manager",
                   mapToPrincipals={ "juliet","amanda" }),
    @SecurityRole (role="vp")
} )
@RolesReferenced (
    @SecurityRoleRef (role="mgr", link="manager")
)
public class SecurityRolesImpl {
...

In the example, the role mgr is linked to the role manager, which is allowed to invoke the Web Service. This means that any user who is assigned to the role of mgr is also allowed to invoke the Web Service.

Description

Target: Class

Specifies whether the client is required to use the HTTPS transport when invoking the Web Service.

WebLogic Server establishes a Secure Sockets Layer (SSL) connection between the client and Web Service if the transport attribute of this annotation is set to either Transport.INTEGRAL or Transport.CONFIDENTIAL in the JWS file that implements the Web Service.

If you specify this annotation in your JWS file, you must also specify the weblogic.jws.WLHttpTransport annotation (or the <WLHttpTransport> element of the jwsc Ant task) to ensure that an HTTPS binding is generated in the WSDL file by the jwsc Ant task.

Attributes

transport

Example

package examples.webservices.security_https;
import weblogic.jws.security.UserDataConstraint;
...
@WebService(name="SecurityHttpsPortType",
            serviceName="SecurityHttpsService",
            targetNamespace="http://example.org")
@UserDataConstraint(
           transport=UserDataConstraint.Transport.CONFIDENTIAL)
public class SecurityHttpsImpl {
...

Description

Target: Class

Specifies the name of the Web Service security configuration you want the Web Service to use. If you do not specify this annotation in your JWS file, the Web Service is associated with the default security configuration (called default_wss) if it exists in your domain.

The @WssConfiguration annotation only makes sense if your Web Service is configured for message-level security (encryption and digital signatures). The security configuration, associated to the Web Service using this annotation, specifies information such as whether to use an X.509 certificate for identity, whether to use password digests, the keystore to be used for encryption and digital signatures, and so on.

WebLogic Web Services are not required to be associated with a security configuration; if the default behavior of the Web Services security runtime is adequate then no additional configuration is needed. If, however, a Web Service requires different behavior from the default (such as using an X.509 certificate for identity, rather than the default username/password token), then the Web Service must be associated with a security configuration.

Before you can successfully invoke a Web Service that specifies a security configuration, you must use the Administration Console to create it. For details, see "Create a Web Services security configuration" in the Oracle WebLogic Server Administration Console Help. For general information about message-level security, see "Configuring Message-Level Security" in Securing WebLogic Web Services for Oracle WebLogic Server.

Attributes

value

Example

The following example shows how to specify that a Web Service is associated with the my_security_configuration security configuration; only the relevant Java code is shown:

package examples.webservices.wss_configuration;
import javax.jws.WebService;
...
import weblogic.jws.security.WssConfiguration;
@WebService(...
...
@WssConfiguration(value="my_security_configuration")
public class WssConfigurationImpl {
...

Description

Target: Method

Specifies the mapping of a Web Service operation onto the SOAP message protocol.

This annotation is analogous to @javax.jws.soap.SOAPBinding except that it applies to a method rather than the class. With this annotation you can specify, for example, that one Web Service operation uses RPC-encoded SOAP bindings and another operation in the same Web Service uses document-literal-wrapped SOAP bindings.

Attributes

style

use

parameterStyle

Example

The following simple JWS file shows how to specify that, by default, the operations of the Web Service use document-literal-wrapped SOAP bindings; you specify this by using the @javax.jws.soap.SOAPBinding annotation at the class-level. The example then shows how to specify different SOAP bindings for individual methods by using the @weblogic.jws.soap.SOAPBinding annotation at the method-level. In particular, the sayHelloDocLitBare() method uses document-literal-bare SOAP bindings, and the sayHelloRPCEncoded() method uses RPC-encoded SOAP bindings.

package examples.webservices.soap_binding_method;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import weblogic.jws.WLHttpTransport;

               parameterStyle=SOAPBinding.ParameterStyle.BARE)
  public String sayHelloDocLitBare(String message) {
    System.out.println("sayHelloDocLitBare" + message);
    return "Here is the message: '" + message + "'";
  }
  @WebMethod()
  @weblogic.jws.soap.SOAPBinding(
               style=SOAPBinding.Style.RPC,
               use=SOAPBinding.Use.ENCODED)
  public String sayHelloRPCEncoded (String message) {
    System.out.println("sayHelloRPCEncoded" + message);
    return "Here is the message: '" + message + "'";
  }
}

Description

Target: Class, Method

Specifies the roles that are allowed to access the operations of the Web Service.

If you specify this annotation at the class level, then the specified roles apply to all public operations of the Web Service. You can also specify a list of roles at the method level if you want to associate different roles to different operations of the same Web Service.

Attributes

rolesAllowed

rolesReferenced

Example

The following example shows how to specify, at the class-level, that the Web Service can be invoked only by the Admin role; only relevant parts of the example are shown:

package examples.webservices.security_roles;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
import weblogic.ejbgen.Session;
import javax.jws.WebService;
...
import weblogic.jws.security.SecurityRoles;
@Session(ejbName="SecurityRolesEJB")
@WebService(...
// Specifies the roles who can invoke the entire Web Service
@SecurityRoles(rolesAllowed="Admnin")
public class SecurityRolesImpl implements SessionBean {
...

Description

Target: Class

Specifies the identity assumed by the Web Service when it is invoked.

Unless otherwise specified, a Web Service assumes the identity of the authenticated invoker. This annotation allows the developer to override this behavior so that the Web Service instead executes as a particular role. The role must map to a user or group in the WebLogic Server security realm.

Attributes

value

Example

The following example shows how to specify that the Web Service, when invoked, runs as the Admin role:

package examples.webservices.security_roles;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
import weblogic.ejbgen.Session;
import javax.jws.WebService;
...
import weblogic.jws.security.SecurityIdentity;
@Session(ejbName="SecurityRolesEJB")
@WebService(...
// Specifies that the Web Service runs as the Admin role
@SecurityIdentity( value="Admin")
public class SecurityRolesImpl implements SessionBean {
...

Description

Target: Class, Method

Specifies an array of @weblogic.wsee.jws.jaxws.owsm.SecurityPolicy annotations.

Use this annotation if you want to attach more than one Oracle Web Services Manager (Oracle WSM) WS-Policy files to a class or method of a JWS file. If you want to attach just one Oracle WSM WS-Policy file, you can use the @weblogic.wsee.jws.jaxws.owsm.SecurityPolicy on its own.

See "Using Oracle Web Service Security Policies" in Securing WebLogic Web Services for Oracle WebLogic Server for detailed information and examples of using this annotation.

This JWS annotation does not have any attributes.

Example

@SecurityPolicies({
    @SecurityPolicy(uri="policy:firstPolicy.xml"),
    @SecurityPolicy(uri="policy:secondPolicy.xml")
  })

Description

Target: Class, Method

Specifies that an Oracle Web Services Manager (Oracle WSM) WS-Policy file, which contains information about digital signatures or encryption, should be applied to the request or response SOAP messages.

This annotation can be used on its own to apply a single Oracle WSM WS-Policy file to a class or method. If you want to apply more than one Oracle WSM WS-Policy file to a class or method, use the @weblogic.wsee.jws.jaxws.owms.SecurityPolicies annotation to group them together.

This annotation can be applied at the class level only, indicating that the Oracle WSM WS-Policy file or files are applied to every public operation of the Web Service.

The Oracle WSM WS-Security policies are not advertised in the WSDL of a WebLogic Server JAX-WS Web service. (Typically, the policy file associated with a Web service is attached to its WSDL, which the Web services client runtime reads to determine whether and how to digitally sign and encrypt the SOAP message request from an operation invoke from the client application.)

See "Using Oracle Web Service Security Policies" in Securing WebLogic Web Services for Oracle WebLogic Server for detailed information and examples of using this annotation.

Attribute

uri

@SecurityPolicy(uri=

Description

Target: Class, Method

Specifies whether the annotated class or method runs inside of a Web service atomic transaction.

If you specify the @Transactional annotation at the Web service class level, the settings apply to all two-way synchronous methods defined by the service endpoint interface. You can override the flow type value at the method level; however, the version must be consistent across the entire transaction.

WebLogic Web services enable interoperability with other external transaction processing systems, such as Websphere, JBoss, Microsoft .NET, and so on, through the support of the following specifications:

• WS-AtomicTransaction Version (WS-AT) 1.0, 1.1, and 1.2: http://docs.oasis-open.org/ws-tx/wstx-wsat-1.2-spec-cs-01/wstx-wsat-1.2-spec-cs-01.html

• WS-Coordination Version 1.0, 1.1, and 1.2: http://docs.oasis-open.org/ws-tx/wstx-wscoor-1.2-spec-cs-01/wstx-wscoor-1.2-spec-cs-01.html

Attributes

version

@Transactional(version=
     Transactional.Version.WSAT10])

value

The following table summarizes the valid values for flow type and their meaning on the Web service and client. The table also summarizes the valid value combinations when configuring web service atomic transactions for an EJB-style web service that uses the @TransactionAttribute annotation.

Example

@Transactional(value = Transactional.TransactionFlowType.SUPPORTS,
     version="Transactional.Versino.WSAT12
