EJB Development using WSAD v5.1

Audience	Developers and other advanced Java professionals that will be designing, developing and creating enterprise-wide applications using Enterprise JavaBeans and implementing them in the WebSphere v5.1 environment
Duration	3 Days
Course Abstract	This course utilizes a combination of instructor-led discussions and interactive workshops to demonstrate the capabilities of IBM’s WebSphere Studio Application Developer v5.1 IDE for the development of enterprise applications using Enterprise JavaBeans in an N-tier architecture. The implementation of these components and their access via servlet clients will be discussed. Each student will learn the following: build session, Message and entity EJBs, use the EJB Universal Test Client, create container-managed and bean-managed entity beans, connect EJBs using transactions, understand the role of EJB containers, utilize activation and passivation, JNDI usage and the deployment of enterprise JAR and EAR components using IBM’s WebSphere Application Server v5.1 and illustrating J2EE design patterns for EJBs.
Objectives	Upon conclusion participants will have acquired these skills: Understand the EJB capabilities of the WSAD v5.0 for projects and perspectives Define and utilize a servlet EJB client and Enterprise JavaBeans Understand the role the session, entity and Message EJBs for J2EE enterprise applications llustrate the role of JMS and message-driven beans in EJB v2.0 Create Bean-managed persistent EJBs (BMP) Use WSAD to create a Container-managed persistent EJB (CMP) Creation of entity EJBs and defining container-managed relationships using WSAD RDB mapping wizard Demonstrate the use of Universal Test Client for testing EJBs Discuss the implementation of EJBs using EJS servers and the role of the EJB containers Using transactions with EJBs using JTA Understand EJB deployment for JAR and EAR files Acquire knowledge of J2EE Design Patterns and Best Practices for EJBs
Class Format	Lecture and Lab
Prerequisites	Each student should have a thorough understanding of the Java language and use of the WebSphere Studio Application Developer IDE v5.1. Additionally, experience with JavaBeans, relational databases and server-side development concepts is preferred.
