The Application Developer configuration of WebSphere Studio provides many helpful tools for integrating EJBs and J2EE enterprise applications. In this tutorial, we'll step through the various EJB tooling features to build the necessary components to connect a J2EE application to a back-end data source. This step-by-step approach also covers the differences between entity and session beans, CMP and BMP, setting associations, and, finally, testing the application in Application Developer's Test Environment.

Prerequisites

This is a simple walk-through of the EJB tools within Application Developer. Java developers not familiar with EJBs should easily be able to see the process and benefits of developing EJBs in an IDE like Application Developer. This is a step-by-step look at letting "the tool" do most of the work for you, so prior knowledge of Enterprise JavaBeans is not required in any way.


System requirements

Application Developer is a complete development environment that provides everything you need for developing and deploying a J2EE application, with the exception of the database. So, both Application Developer and DB2 will be necessary to develop our application.
