Part one introduces EJBs as a part of Java 2 Enterprise Edition (J2EE) and covers the basic concepts and the architecture. Best practice guidelines for successful implementations of EJBs are also discussed.

Part two demonstrates a sample banking application and then implements entity beans, session beans, and message-driven beans using WebSphere Studio Application Developer. Finder methods, different mapping strategies and simple clients that use the EJBs are also implemented. The paper concludes with how to deploy EJB applications to a WebSphere Application Server.
