EJB 3 is the most important innovation introduced in Java EE 5.0. EJB 3 simplifies

enterprise development, abandoning the complex EJB 2.x model in favor

of a lightweight POJO framework. The new API represents a fresh perspective

on EJB without sacrificing the mission of enabling business application developers

to create robust, scalable, standards-based solutions.

and the Java Persistence API quickly and easily. For newcomers to EJB, this book

provides a solid foundation in EJB. For the developer moving to EJB 3 from EJB

2, this book addresses the changes both in the EJB API and in the way the developer

should approach EJB and persistence.
