Before taking this course, students should have practical experience with the Java programming language.
This 5-day instructor-led course teaches students how to build Java Platform, Enterprise Edition 5 (Java EE 5) applications that use Enterprise JavaBeans (EJB) 3.0 and the Java Persistence API (JPA).Java EE 5 represents a significant evolution in the Java enterprise programming model. It provides application developers with considerable improvements that enhance the development experience and, in turn, productivity. In particular, the EJB 3.0 specification in Java EE 5 provides simplified business logic development, simplified testing and dependency management, and simplified object-relational persistence.In this course, students learn about the Java EE 5 component model and the new techniques employed in Java EE 5, such as dependency injection and annotation-based programming. Students also learn how to develop and test the supported types of EJBs (session and message-driven) and JPA entities. Â Finally, students gain experience with the various qualities of service provide by the EJB container such as security and transactions, how to create Web services from EJBs, and how to develop EJB clients.IBM WebSphere Application Server V7 and IBM Rational Application Developer V7.5 provide complete support for the EJB 3 specification. Hands-on exercises throughout this course give students practical experience developing EJBs with IBM Rational Application Developer V7.5 and deploying EJB-based applications to IBM WebSphere Application Server V7.
