weblogic.security.service
Class EJBResource

java.lang.Object
  weblogic.security.service.ResourceBase
      weblogic.security.service.EJBResource

All Implemented Interfaces:: Serializable, Resource, SelfDescribingResource, SelfDescribingResourceV2

public final class EJBResource
extends ResourceBase
extends ResourceBase

The EJBResource class is used by a container to specify the EJB resource (and method related to the resource) that a caller is attempting to access.

The toString format (which is produced by the ResourceBase class) for an EJB resource is:
type=<ejb>, app=myApp, module=MyJarFile, ejb=myEJB, method=myMethod, methodInterface=Home, methodParams={argumentType1, argumentType2}

Constructor Detail

EJBResource

public EJBResource(String app,
                   String module,
                   String ejb,
                   String method,
                   String methodInterface,
                   String[] methodParams)

Constructs a new EJBResource with a target name composed from the app, module, ejb, method, methodInterface, and methodParams parameters.

For example, if the ejb-jar.xml deployment descriptor in myejbs.jar (which is inside myApp.ear) contains the following elements:

<method-permission> <role-name>MyRole</role-name> <method> <ejb-name>MyEJB</ejb-name> <method-name>*</method-name> </method> </method-permission>

Then the resource to access the home interface of this bean would be type=<ejb>, application=myApp, module=myejbs, ejb=MyEJB, method=myMethod, methodInterface=Home, signature={argumentType1,argumentType2} and its parentage would be:

type=<ejb>, application=myApp, module=myejbs, ejb=MyEJB, method=myMethod, methodInterface=Home type=<ejb>, application=myApp, module=myejbs, ejb=MyEJB, method=myMethod type=<ejb>, application=myApp, module=myejbs, ejb=MyEJB type=<ejb>, application=myApp, module=myejbs type=<ejb>, application=myApp type=<app>, application=myApp type=<ejb>

Parameters:

app - a String indicating the name of the application in which the resource is deployed, as it appears in the corresponding <display-name> element. The <display-name> element is associated with an <application> element in the deployment descriptor, in an .ear file. A value of null indicates that the resource is not deployed as part of an application.

module - a String name of the module, as it appears in the corresponding <display-name> element. The <display-name> is associated with the <ejb-jar> element in the deployment descriptor. Because the <display-name> element is optional in the <ejb-jar> element of the deployment descriptor, the name of the .jar file containing the EJB, less the '.jar' extension, may be used in its absence.

ejb - a String representing the name of the EJB, as it appears in the corresponding <ejb-name> element in the deployment descriptor.

method - a String representing the name of the method on the EJB resource, as it appears in the corresponding <method-name> element in the deployment descriptor. A value of null indicates that the security policy for the resource pertains to all methods that match the other parameters of the resource specification, without consideration of the method name.

methodInterface - a String representing the EJB interface of the resource, as it appears in the corresponding <method-intf> element in the deployment descriptor. A value of null indicates that the security policy for the resource pertains to all methods that match the other parameters of the resource specification, without consideration of the type of interface on which they occur. Valid values for this parameter are restricted to the following:

Home
Remote
LocalHome
Local

methodParams - an array of Strings used to specify the parameter signature of the target method. Each element in the array contains the fully-qualified Java classname of the corresponding parameter signature, as it appears in the corresponding <method-param> elements (associated with the <method-name> element in the deployment descriptor). The order of the elements in the array must take the order of the arguments found in the method signature. An empty array is used to represent a method signature with no arguments. A value of null indicates that the security policy for the resource pertains to all methods that match the other parameters of the resource specification, without consideration of the method signature.

Method Detail

initialize

public void initialize(String application,
                       String module,
                       String ejb,
                       String method,
                       String methodInterface,
                       String[] methodParams)

Deprecated. As of 04/01/02, the constructor should be used instead.

Replaces application, module, ejb, method, methodInterface, and methodParams parameters of the resource with the specified values.

Parameters:

application - a String indicating the name of the application in which the resource is deployed, as it appears in the corresponding <display-name> element. The <display-name> element is associated with an <application> element in the deployment descriptor, in an .ear file. A value of null indicates that the resource is not deployed as part of an application.

ejb - a String representing the name of the EJB, as it appears in the corresponding <ejb-name> element in the deployment descriptor.
