Before you start

About this tutorial

This tutorial shows you how to use many of the tools included in the Eclipse Web Tools Platform (WTP) to create a J2EE sample brokerage application that implements both POJO and EJB Web service endpoints. You'll use IBM DB2® Express-C as the database for the application, and you'll use the Community Edition server adapter to deploy the application to an Community Edition instance. Afterward, you'll use the Eclipse WTP Web service testing functions to test your Web services and write clients to invoke them.
