This IBM® Redpaper™ publication introduces Enterprise JavaBeans (EJB) and demonstrates by example how to create, maintain, and test EJB components. It explains how to develop session beans and describes the relationships between the session beans and the Java Persistence API (JPA) entity beans. Then, it integrates the EJB with a front-end web application for the sample application. It includes examples for creating, developing, and testing the EJB by using IBM Rational® Application Developer.
The paper is organized into the following sections:
- Introduction to Enterprise JavaBeans
- Developing an EJB module
- Testing the session EJB and the JPA entities
- Invoking EJB from web applications
- More information
This paper is intended for developers interested in creating, maintaining, and testing EJB components using IBM Rational Application Developer.
This paper was originally published as a chapter in the IBM Redbooks® publication, Rational Application Developer for WebSphere Software V8 Programming Guide, SG24-7835.
