EJB 3 is the most important innovation introduced in Java EE 5.0. EJB 3 promises to simplify enterprise development, abandoning the heavyweight EJB 2.x model in favor of a lightweight POJO framework. The API represents a lot of hard work, honest introspection, and a fresh perspective on EJB, all without sacrificing the mission of enabling business application developers to create robust, scalable, standards-based solutions.
In the tradition of Manning's In Action series, this book tackles the subject matter head-on, through numerous code samples, real-life scenarios, and illustrations. It is geared toward helping you learn EJB 3 quickly and easily. The authors make the subject matter approachable, covering the basics where needed as well as providing guidance, deep coverage, and best practices. The book highlights what EJB 3 has to offer without disregarding the contributions and strengths of seminal technologies like Spring, Hibernate or TopLink.
