In this EJB3 course, authored and taught by Sun Microsystems, you will learn how to develop robust back-end functionality using EJB 3.0 technology. You will work on an online auction scenario, which will demonstrate how to leverage container-managed services with session and message beans and entity classes to resolve the real-world problems presented by an electronic commerce application.

Throughout this course, you will gain practical EJB technology coding experience, whilst you will also be introduced to the designs and best practices used to solve transaction, messaging, and security issues.
