Creating a Web service JavaServer Faces client

The Web Service Discovery Dialog allows you to discover a Web service that exists online or in the workspace, create a proxy to the Web service, and then place the methods of the proxy on a Faces JSP file:

Remove the RAD75WebServiceClientEAR from the server using Add and Remove Projects (we will add a project to the EAR and automatic publishing gets into the way). Alternatively, expand the server, right-click the project, and select Remove.

Create a dynamic Web project by selecting File Æ New Æ Dynamic Web Project.

Enter RAD75WebServiceJSFClient as the project name.

In the Configurations section, select JavaServer Faces v1.2 Project to add the required JSF facets to the project facets list.

Select RAD75WebServiceClientEAR as the EAR project name.

Click Finish (Figure | 8-18).

If you are prompted to open the Web perspective, click Yes.
