What Are Web Services?

A Web service is a program that can be accessed remotely using different XML-based languages. What this program can do (that is, the functionality it implements) is described in a standard XML vocabulary called Web Services Description Language (WSDL). For example, a banking Web service may implement functions to check an account, print a statement, and deposit and withdraw funds. These functions are described in a WSDL file that any consumer can invoke to access the banking Web service. As a result, a consumer does not have to know anything more about a Web service than the WSDL file that describes what it can do.

A Web service consumer (such as, a desktop application or a Java Platform, Enterprise Edition client such as a portlet) invokes a Web service by submitting a request in the form of an XML document to a Web service provider. The Web service provider processes the request and returns the result to the Web service consumer in an XML document as shown in the example below.

In this example, the Web service consumer sends a request in the form of a Simple Object Access Protocol (SOAP) message (SOAP is an XML messaging framework designed to allow heterogeneous applications to exchange structured information in a distributed environment). The Web service provider (www.xmethods.com) processes the request and returns the response, in this case the stock quote for Oracle. In the example above, the Web service provider may have asked for credentials to access the service, for example a username and a password. Also, the Web service provider may have encrypted the response (the value of the stock).

You can also develop Representational State Transfer (REST) Web services, or "RESTful" Web services. REST describes any simple interface that transmits data over a standardized interface (such as HTTP) without an additional messaging layer, such as SOAP. REST provides a set of design rules for creating stateless services that are viewed as resources, or sources of specific information, and can be identified by their unique URIs. A client accesses the resource using the URI, a standardized fixed set of methods, and a representation of the resource is returned. The client is said to transfer state with each new resource representation.

In summary, Web services are loosely coupled, distributed environments that allow companies to integrate heterogeneous applications within the enterprise or expose business functions to their customers and partners over the Internet.

Web services are characterized by three factors:

What they do (the business functionality they expose),

Where they are (the web site which exposes that functionality),

How they can be accessed (the set of published interfaces necessary to use the exposed functionality).

Web services rely on XML-based industry standards:

Extensible Markup Language (XML)—A data format that allows uniform communication between Web services consumers and Web services providers.

XML Schema—A framework that describes XML vocabularies used in business transactions.

SOAP—A protocol for exchanging structured information in the implementation of Web services.

WSDL—An XML-based language providing a model for describing Web services.

WS-Policy—The WS-Policy framework provides a flexible and extensible grammar for describing the capabilities, requirements, and general characteristics of Web services using policies.

Universal Description, Discovery, and Integration (UDDI)—A framework to publish and look up Web services on the Internet.

Overview of Web Services in Oracle Fusion Middleware 11g

The following illustration shows common interactions between Oracle Fusion Middleware Web services and clients, and identifies Web service policy support at each interaction point.

The Oracle Web Services Manager (WSM) Policy Manager is the security and management policy lynchpin for Oracle Fusion Middleware 11g Web services. For more information about how the Oracle WSM Policy Manager provides the policy framework for managing policies, see "Understanding Oracle WSM Policy Framework" in Security and Administrator's Guide for Web Services.

Web Services Architecture

In Oracle Fusion Middleware 11g, there are two categories of Web services:

Oracle Infrastructure Web services—SOA, ADF, and WebCenter services

WebLogic Web services (Java EE Web services)

The following figure illustrates the two Web services categories.

Figure 2 Web Services in Oracle Fusion Middleware 11g

Types of Web Services and Clients

Table 1 summarizes the types of Web services supported in Oracle Fusion Middleware 11g.

Note:

All Web services and clients can be deployed to an Oracle Fusion Middleware environment that runs on Oracle WebLogic Server. Oracle WebLogic Web services can be deployed to a standalone Oracle WebLogic Server, as well.

Table 1 Oracle Fusion Middleware Web Services

Web Service
Description

WebLogic Web service (Java EE)

WebLogic Web services are implemented according to the Web services for Java EE specification, available at http://www.jcp.org/en/jsr/detail?id=109, that defines the standard Java EE runtime architecture for implementing Web services in Java.

For more information about developing WebLogic Web services, see:

Introducing Web Services in Oracle WebLogic Server

Getting Started Using JAX-WS Web Services for Oracle WebLogic Server

Getting Started Using JAX-RPC Web Services for Oracle WebLogic Server

"Developing with Web Services" in the Oracle JDeveloper online help.

You can deploy WebLogic Web services to any Oracle WebLogic Server environment, including a standalone environment.

SOA service components

SOA composite applications include SOA service components. SOA service components are the basic building blocks of SOA applications, implementing a part of the overall business logic functionality.

The following SOA service components can be managed using Oracle WSM:

BPEL Process—Provides process orchestration and storage of synchronous and asynchronous processes.

Oracle Mediator—Routes events (messages) between different components.

Human Workflow—Enables you to model a workflow that describes the tasks for users or groups to perform as part of an end-to-end business process flow.

Business Rules—Design a business decision based on rules.

For more information about developing SOA service components, see Developer's Guide for Oracle SOA Suite.

You can deploy SOA service components to the Oracle Fusion Middleware environment.

SOA service binding components

SOA Service binding components provide the outside world with an entry point to the SOA composite application. The WSDL file of the service advertises its capabilities to external applications. These capabilities are used for contacting the SOA composite application components. For more information, see Developer's Guide for Oracle SOA Suite.

ADF Business Components

ADF Business Components simplify the development, delivery, and customization of business applications for the Java EE platform by providing a library of reusable components and supporting design time facilities in Oracle JDeveloper.

Using ADF Business Components, developers are not required to write the application infrastructure code required by the typical Java EE application to perform the following tasks:

Connect to the database.

Retrieve data.

Lock database records.

Manage transactions.

Additionally, Oracle JDeveloper facilities expose ADF Business Component application modules that encapsulate built-in data manipulation operations and custom methods as Web services so that a service-enabled application module can be consumed across modules of the deploy Fusion Web application.

For more information, see "Integrating Service-Enabled Application Modules" in Fusion Developer's Guide for Oracle Application Development Framework.

WebCenter services

WebCenter services expose Web 2.0 technologies for social networking and personal productivity, such as Wiki, RSS, and blogs. WebCenter provides a set of features and services (for example, portlets, customization, and content integration) that you can selectively add to your application. For more information about integrating WebCenter services, see Developer's Guide for Oracle WebCenter.

Table 2 summarizes the types of Web service clients supported in Oracle Fusion Middleware 11g.

Table 2 Oracle Fusion Middleware Web Service Clients

Web Service Client
Description

Web service clients

Client applications that invoke WebLogic Web services can be written using any technology: Java, Microsoft .NET, and so on.

There are two types of client applications:

Stand-alone—A stand-alone client application can be a Java application, a .NET client, or any other type of client able to submit a Web service request. It runs completely separately from WebLogic Server.

A Java EE component deployed to WebLogic Server—In this type of client application, the Web service runs inside a Java Platform, Enterprise Edition (Java EE) Version 5 component deployed to WebLogic Server, such as an EJB, servlet, or another Web service. This type of client application, therefore, runs inside a WebLogic Server container.

For more information about developing WebLogic Web service clients, see:

"Invoking Web Services" in Getting Started With JAX-WS Web Services for Oracle WebLogic Server

"Developing with Web Services" in the Oracle JDeveloper online help

SOA reference binding components

SOA reference binding components connect the SOA composite application to external partners. For more information about developing SOA reference binding components, see Developer's Guide for Oracle SOA Suite.

ADF Web applications

ADF Web applications can invoke a service, such as a WebLogic Web service, a SOA composite application, or a service-enabled ADF application module. For more information, see Developer's Guide for Oracle SOA Suite.

In addition, ADF Web applications can work with Web services in the user interface using a Web service data control. For more information about generating service-enabled application modules, calling a Web service from an ADF application module, or creating Web service data controls, see Fusion Developer's Guide for Oracle Application Development Framework.

WebCenter portlets

WebCenter portlets enable you to surface WebCenter services. For more information about developing WebCenter portlets, see Developer's Guide for Oracle WebCenter.

Types of Web Service Policies

As shown in Figure 2, there are two types of policies that can be attached to Web services.

Table 3 Types of Web Service Policies

Type of Policy
Description

Oracle Web Services Manager (WSM) Policy

Policy provided by the Oracle WSM. For more information about the Oracle WSM and the predefined policies, see Oracle Fusion Middleware Security and Administrator's Guide for Web Services.

You can attach Oracle WSM policies to Oracle Infrastructure Web services. You can only attach Oracle WSM security policies to WebLogic JAX-WS Web services.

You manage Oracle WSM policies from Oracle Enterprise Manager Fusion Middleware Control.

WebLogic Web Service Policy

Policy provided by WebLogic Server. For more information about the WebLogic Web service policies, see Securing WebLogic Web Services for Oracle WebLogic Server.

A subset of WebLogic Web service policies interoperate with Oracle WSM policies. For more information, see "Interoperability with Oracle WebLogic Server 11g Web Service Security Environments" in the Interoperability Guide for Oracle Web Services Manager.

You manage WebLogic Web service policies from WebLogic Administration Console.

Note:

It is recommended that you use Oracle WSM policies over WebLogic Web services whenever possible. You cannot mix your use of Oracle WSM and WebLogic Web service policies on the same Web service.

Tools for Web Service Development, Security, and Administration

To develop Web services, you can use the tools described in the following table, or your favorite IDE.
