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.
What's Inside
* Building Business Logic with POJO Session Beans and Message Driven Beans
* EJB 3 Dependency Injection and Interceptors
* Domain Modeling and Object-Relational Mapping with the EJB 3 Java Persistence API
* Effectively manipulating and retrieving entities, including using the Java Persistence Query Language
* Using EJB 3 from other tiers (such as the web or application client tier) and frameworks such as Spring
* Best practices, performance tuning, and design patterns
* Migrating from EJB 2.x and other POJO frameworks

Not as good for beginners
This book is full of grammatical errors and typos. The errata (although incomplete) at the book's website reveals it.
However, Part 3 (DIVING INTO THE JAVA PERSISTENCE API), covering chapters 7, 8, 9, 10 are excellently written - clear & concise with appropriate examples, albeit some typos.
The rest of the chapters are hard to read and understand because of the writing style & grammar. If you are an experienced EJB developer or has experience with prior EJB versions, like myself, you should probably be able to make out what the authors are trying to say.
Their desperate attempts to humour were funny at times and completely off, and they even talk about cognitive learning - thanks to Head First series, that I consider a break through in the way technology books are written.
Definitely not recommended for beginners.

Excellent book for SCBCD ,,,, and SCEA too !!
I can say only one thing: This book is really excellent !!
I wanted to upgrade my SCBCD certification to EJB3 but I did not know which book I should read,,so, after reading some good and bad reviews about the book.
I gave it a try,,and I started reading. Finding out that it's easy to understand, easy to follow and I would say that it does not matter if you are a beginner or advance in EJB programming.
This book really helps you to understand, it guides you in every chapter. I gave the book to my brother so he may learn EJB and get the certification soon. He is beginner in EJB and he has told me good things about the book.
I did read it twice for my certification, except some chapters that are not part of the exam. For example Spring and EJB but I'll give a try later ;)
Definitely I recommend it,,.
For those who are interested in SCEA certification,,.this book is also a GOOD option.

Too many comparisons of EJB2 make this book boring.
This is a good book in general. Yet the author spent too many pages comparing EJB 2 and EJB 3 and keep telling people why EJB 2 is so bad. Such complaints about EJB 2 makes a quite large part of the first part of the book, which is too boring for people not coming from the EJB 2 world. Maybe `From EJB2 to EJB3` is a better title for the book.

A book for those who want to get fast up with EJB 3
I recently got this book to speed up with EJB3 instead of reading all the JavaEE specs and making the wrong assumptions. This books takes you on a fantastic JavaEE journey and makes you able to play with JavaEE after the end of that journey.

Fantastic introduction to EJB 3 technology
It's a fantastic introduction to EJB 3. There is a lot of content about JPA, mainly. If you will be starting with EJB 3, this book is really interesting.
I passed on SCBCD after I read this book (and EJB 3 spec).
