About this book

EJB 2 is widely used but it comes at a cost—procedural, redundant code. EJB 3 is a different animal. By adopting a POJO programming model and Java 5 annotations, it dramatically simplifies enterprise development. A cool new feature, its Java Persistence API, creates a standard for object-relational mapping. You can use it for any Java application, whether inside or outside the EJB container. With EJB 3 you will create true object-oriented applications that are easy to write, maintain and extend.EJB 3 in Action is a fast-paced tutorial for both novice and experienced Java developers. It will help you learn EJB 3 and the JPA quickly and easily. This comprehensive, entirely new EJB 3 book starts with a tour of the EJB 3 landscape. It then moves quickly into core topics like building business logic with session and message-driven beans. You’ll find four full chapters on the JPA along with practical code samples, design patterns, performance tuning tips, and best practices for building and deploying scalable applications.

Reader's Thoughts

The source code is almost impossible to read on kindle and samples do not work.

This book just isn't very good. There are much better books about JPA and the coverage in this book of anything other than entity beans is weak.

Daniel

Good book for a day to day quick access to necessary information

David Robillard

Very precise intro to EJB 3.1 All Java EE Devs and Admins should read this one.

Thought “EJB 3 in Action” (first edition) was a great book, so I'm not surprised that I like the second edition as well. In fact a snippet from my first review is on page one of the second edition.I really liked the story at the beginning comparing 3 reincarnations to the three versions of EJB. The Turtle Shipping Company and Snail Trucking example was also very cute. As were the chicken and frog.One page 17, the text after the example talks about not needing an interface, but the code example has an interface. There is also a mix of EJBs and EJB's used in the book. I think this comes from having five authors. (The four real authors plus them originally. Because writing is like code in that after a certain point it is like someone else wrote it.) The fact that these are the worst things I can say about the book, is a good thing though. The explanations were great especially the section on AOP, comparing EJB vs EJB Lite and when to use each session bean type. There are good warnings and caveats throughout. There was also a great intro to Web Sockets.I thought I knew about the topic and still managed to learn a few things. I learned Seam became CDI, that you can use a constructor in the select clause of queries and about the embeddable container.(I really want to give this 4.5 stars, but that isn't an option.)---Disclosure: I received a copy of this book from the publisher in exchange for writing this review on behalf of CodeRanch.
