Java™ 2 Platform, Enterprise Edition (J2EE) 1.4 supports two types of Web service endpoints: Plain Old Java Object (POJO) and Enterprise JavaBeans (EJB) endpoints. IBM® WebSphere® Application Server Community Edition (also referred to as Community Edition in this tutorial) is a J2EE 1.4-certified application server that provides support for these two types of Web service endpoints. This tutorial shows you how to use the Eclipse Web Tools Platform (WTP) to create an enterprise application that implements both POJO and EJB Web services endpoints, using IBM DB2® Express-C as the database for the application. You'll use the Community Edition server adapter (formerly known as the Eclipse plug-in) to deploy the application to a Community Edition instance. And finally, you'll develop a client to call the Web services.
Objectives
- Learn how to develop Web services applications using the Eclipse WTP and the WebSphere Application Server Community Edition server adapter.
- Try out many of the tools included in the Eclipse WTP to create a J2EE sample application that implements both POJO and EJB Web services endpoints.
- Find out how XDoclet can be configured and used with the WTP to generate the boilerplate code required in J2EE applications.
- Learn how to create a data source to connect to DB2 Express-C in Community Edition and how to deploy the application to Community Edition from Eclipse using the server adapter.
- Find out how to use the wscompile tool, packaged with Sun Microsystem's Java WSDP tool, to generate the mapping and WSDL files required to deploy Web services.
- Learn how to test your Web services and write clients to invoke them.
Prerequisites
To succeed with this tutorial, you should be familiar with Java development in general and, specifically, server-side Java development. You should understand the general concepts behind relational databases and be familiar with basic J2EE concepts, such as deployment descriptors and WAR archives. You should also be familiar with XML, XML schemas, Eclipse, and the Eclipse WTP. Prior experience with application servers, Web services, and relational databases is also recommended.
