Editorial Review:
EJB 3 in Action tackles EJB 3 and the Java Persistence API head-on, providing practical code samples, real-life scenarios, best practices, design patterns, and performance tuning tips. This book builds on the contributions and strengths of seminal technologies like Spring, Hibernate, and TopLink. 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. EJB 3 in Action is a fast-paced tutorial, geared toward helping you learn EJB 3 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.

Entertaining EJB3  2008-11-07
One might say that "EJB3 In Action" is actually two books in one. Both EJB3's core functionality (Session beans, message driven beans, interceptors, transactions, exceptions...) and Java Persistence API (JPA) are covered. Learning Enterprise Java Beans is not an easy task, no matter how cleaner EJB3 are compared to EJB2. "EJB3 In Action" achieves to make a lot of advanced topics look easy. Not only does it provide the necessary information to understand EJB3 in an enjoyable style, it also introduces some best practices, performance issues, and illustrates important concepts with relevant code snippets. There is enough examples to keep you busy trying it yourself on your favorite container, as well as the downloadable application which is used throughout the book. There are also chapters about interoperability with EJB2, about using EJB3 with the Spring framework, well enough to satisfy the most curious and avid developers. All in all, the authors have made a fantastic job keeping the reader focused and entertained.
I used this book to study Sun's SCBCD certification. Although the book does not go as deep into the EJB specification as the exam does, I'm confident enough to say that, armed with this book and an exam simulator to fill the gaps, any serious developer can successfully pass.
Excellent Book 2008-10-30
EJB 3 in Action is an excellent introduction and reference book for EJB3. The Manning books are usually a cut above the competition and this one is no different. The also covers the new web services APIs in JEE 5 as well as JPA and ties them all together which greatly enhances the utility of this book. This is the best JEE book I have read to date - explanations and examples are clear an applicable to my work. The book also delves into patterns and good practices and how EJB development has taken a radical leap forward since version 2.
Greate book especially for beginers 2008-10-19
EJB is not an easy topic to learn and read about. But this book starts with explaining basic concept and goes deeper with a very good speed that it doesn't make you feel you are being sunk at the same time it doesn't put you to sleep.
it covers most if not all of the materials of the SCBCD exam, of course you still need to check the spec's but this book gives a great kick start and great level of understanding that makes reading the spec's easier also it makes reading books that act like a reference (such as OReilly's EJB 3.0) easier and trust me everything starts making sense after reading EJB3 in action.
I think book would be perfect if it covers DD with more examples.
Nice work authors.
Perfecdt for getting started with EJB3 2008-10-18
One of my big complaints when I get a technical book is that I often feel like I'm in the Goldilocks and the Three Bears story - technical books are either way out there covering things you don't care about and are too complicated or they don't cover enough to even be relevant for when you actually want to start coding (you know books that just talk about theory and history, bla bla blah.) I found this book to be the "perfect porridge" (to keep with the Three Bears analogy.)
The book doesn't bore you with things you don't care about and covers all the things you "do" need to know and need to care about. It's extremely well written and well organized.
I really appreciate the clear and concise code snippets illustrating PRACTICAL implementations. I emphasize 'practical' because too often technical books provide some weird code snippet that you wouldn't use 'in real life.' This is not the case with the examples in this book. The examples in this book fit perfectly with the text and they don't just waste space pasting in code to fill up pages.
Who would this book be good for? I've had a lot of experience with Java web applications, but NOT EJBs and I found the book VERY easy to follow. Previous knowledge of EJB2 is not necessary at all for comprehending the material. Having some relational database knowledge would certainly come in handy to help understand some of the entity relationships, but even that's not absolutely necessary.
This book is also nice because I found it easy to read while just lying in bed to get a complete feel for the whole gamut of the EJB3 realm.
I highly recommend this book for anyone brand new to EJBs or those coming from the EJB2 world.
Best Easy and Understandable Book 2008-10-17
You know i have been in IT not since long, before i started this book many of my concept's were not clear about EJB3.
after reading this book, you will get to know the status of current technolgie's are.
it almost cover's all concept's related to ejb3 and side by side, it also introduces you to other competing technolgies.
well it's language is too easy, all the chapter's do have a easy language.
well i do enjoy to read this book.
i am learning EJB 3 and the Java Persistence API in an easy manner and without difficulty. For novices to EJB, this book provides a rock-solid foundation to EJB. For developers moving to EJB 3 from EJB 2, this book addresses the changes both in the EJB 3 API and JPA. This book is ideally suited for Java developers with a couple of years' experience who are interested in EJB 3.
