There is no limit for the types of Web Service clients. For example, you can develop the Web Service clients mentioned below. When developing a Web Service client operating on a J2EE container, use the EJB version 3.0 or later, and Servlet version 2.5 or later for Web applications such as the JSP or servlets. For example, when including web.xml in a WAR file by using a Web application, use the web.xml version 2.5 or later.

• Java applications (Calling Web Services from a Java application)
• JSPs (Invoking Web Service from JSPs)
• Servlets (Invoking Web Services from servlets)
• EJBs (Invoking Web Services from EJBs)
• Web Services (Invoking another Web Service from the Web Service Implementation Class)

With the JAX-WS functionality of Cosminexus, you can implement a Web Service client using any of the following methods:

• Using a service class and stubs (Developing stub-based Web Service clients)
• Using the javax.xml.ws.Dispatch interface (Developing dispatch-based Web Service clients)
• Using other JAX-WS APIs (Developing API-based Web Service clients)

This section describes the examples of implementing Web Service clients. This section also describes the precautions to be taken for using a service class and ports.
