208 IBM WebSphere Everyplace Access V5, Volume II: Application Development
7.1 Overview
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:
a. Create a sample Web project and import an existing JavaBean class.
b. 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. Develop a Web Services client portlet to access the sample Web Service.
The scenario illustrated in Figure 7-1 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 7-2 on page 209.
