Overview:

This course takes you beyond the fundamentals of Enterprise Java Bean (EJB 3.0) programming using Eclipse. In this course, you will learn about building message-driven Beans, EJB Security, utilizing Web Services technologies like JAX-WS, and managing distributed transactions. You will also be exposed to Java Interceptors, EJB Timer service, Hibernate JPA caching, EJB design patterns, and deployment.

Prerequisites: This course is intended for intermediate to advanced Java programmers. System architects will find the advanced concepts especially beneficial in designing a framework. Students should have good Java programming knowledge and should be familiar with web application programming, including servlets and JSPs.
