IBM Websphere Portal V5: A Guide for Portlet Application Development

In this section, we show the most important steps required to develop a Web Service client portlet accessing a local or remote Web Service. In most cases, the following tasks will be executed:

1. Develop a sample Web Service from a JavaBean. This Web Service will be used to test and run the Web Service client portlet. The following tasks are required:

   1. Create a sample Web project and import an existing JavaBean class.

   2. Using the available wizards in WebSphere Studio Site Developer, transform this JavaBean into a Web Service so it can be accessed from portlet applications.

2. Using the wizards provided by WebSphere Studio Site Developer, create a Web Services client portlet project to access the sample Web Service.

The scenario illustrated in Figure 9-1 shows how portlet applications can be easily integrated with existent Web Services without the need to write extra code.

The development workstation used to create the sample application is illustrated in Figure 9-2 on page 293.
