About this tutorial

Building applications using the Java™ 2 Enterprise Edition architecture can be an intimidating process. The Eclipse Web Tools Platform provides a base set of tools to make developing in this environment easier.

This tutorial shows you how to create a simple Web service using IBM's Web Tools Platform contribution to the Eclipse project. You will build a simple auction Web service that interacts with a Cloudscape (Apache Derby) database. The resulting Web service is then deployed to Apache Tomcat 4.1. As an alternative, this tutorial also includes instructions for migrating the example to an IBM DB2® Universal Database Express V8.2 and IBM WebSphere® Application Server Express 5.1 environment.

The scope of this tutorial is limited to listing items for auction and querying item records from the auction server. Implementing other functions, such as user registration and auction bidding, is left as an exercise for the user.
