Kursbeskrivning: Developing EJB 3 Applications for WebSphere Application Server V7 (Self-Paced)

NOTE: THIS IS AN ONLINE SELF-PACED VIRTUAL COURSE. PLEASE DO NOT MAKE TRAVEL ARRANGEMENTS FOR THIS COURSE.

Self-paced virtual courses provide the same deep technical content as our classroom courses, but allow you to learn on your own schedule. You can stop and start a Self-Paced Virtual class as needed during the 60-day access period.

There is no live instructor for this course, so it may not be appropriate for students who require the guidance of a live instructor. In such cases, students should consider the alternative versions of this course:

• Classroom delivery: WD352, Developing EJB 3 Applications for WebSphere Application Server V7
• Instructor-led online delivery: VD352, Developing EJB 3 Applications for WebSphere Application Server V7 (Remote Class)

Course Overview:

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. 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.

Before taking this course, students should have practical experience with the Java programming language. This knowledge can be gained by attending one of the following courses:

• Java SE 5 Programming Fundamentals (WD152) or (VD152)
• Introduction to Java SE 5 Using Eclipse 3.2 (JA355) or (VD155)

Students should also have knowledge of database concepts such as SQL, primary and foreign keys, joins, and referential integrity.

Some knowledge of Java EE Web development and Web services, and experience with Rational Application Developer or another Eclipse-based development environment, is also beneficial.
