This course utilizes a combination of instructor-led discussions and interactive workshops to demonstrate the capabilities of IBM’s WebSphere Studio Application Developer v5.0 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 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.

Prerequisites

Each student should have a thorough understanding of the Java language and use of the WebSphere Studio Application Developer IDE. Additionally, experience with JavaBeans, relational databases and server-side development concepts is preferred.
