Product Description
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

5.0 out of 5 stars the ejb book - full of practical examples, May 13, 2007

By	Jeanne Boyarsky (New York, NY) - See all my reviews

"EJB 3 in Action" manages to be an excellent read for both people new to EJB and people who have been using EJB 2.X. There are side notes throughout about significant changes from EJB 2.X. For larger topics that someone new to EJB 2.X might not know, the topic is covered in the appendix. The examples are interesting and well written, so it isn't boring reading about the purpose of a session bean if you already know it.

What really impressed me were the differences between this book and Sun's J2EE tutorial. The majority of examples used Java 5 syntax (for looping and the like.) This made the examples feel like EJB 3 examples rather than an old book robotically updated. Further, the authors explain when to use a deployment descriptor vs annotations. Sun sticks to the party line and barely mentions the deployment descriptor. The "EJB 3 in Action" approach is much more useful for gaining practical advice.

Best practices are described throughout. The authors don't assume you know Java 5 features and explain them as necessary. All the expected topics are covered. Additionally, there are chapters on Spring integration and migrating from EJB 2.X. The examples are app server agnostic, but they show you how to use one in the appendix. Finally, the appendixes provide an excellent reference for both the annotations and deployment descriptor.

4.0 out of 5 stars A good introduction to the EJB3 world, May 19, 2007

By	Giannecchini Simone (Camaiore, LU, Italy) - See all my reviews (REAL NAME)

I bought this book since I needed a good introductive book for the ejb3 world in order to get quickly up to speed with all the techinicism.

The book is quite complete, well written, with good examples. It is a very valuable tool to enter the ejb3 world.
The only flaw of this book is, in my humble opinion, the fact that quite a few times advanced topics are explicitly deemed as being out of the scope of the book. I mean, I was expecting that, but anyway I felt a bit delusional since the book was very good.

To summarise, if you want to get a grasp on the ejb3 world quikly I am pretty sure this is the book for you.

4.0 out of 5 stars Convincing introduction to EJB3, June 27, 2007

By	Bas Vodde (Singapore) - See all my reviews

As many of you, I was and am very skeptical about EJBs. They have complicated the enterprise world and haven't really delivered on their promise. Now there is EJB3. When starting the book, I just had one question: Did they "fixed it". After reading this very convincing book, my tentative answer would be: Yes.

"EJB3 in Action" is an easy to read and easy to understand introduction to EJB3. The book doesn't require you to know too much other topics and starts from the beginning. It starts with giving an overview of everything and then from there moves into the different bean types. From there it'll just in the more advanced topics.

One of the things I really liked about the book is that it really tries to answer the questions which I think much of the readers have. Questions like: Why would I use EJB3, I just stopped using EJBs. Can I combine EJBs with spring and how? These are exactly the type of questions people will want answered.

I'm not a EJB expert at all. However, I found the book easy to read and enjoyable. I've learned a lot from the authors while reading the book. I'd recommend it for everyone who wants to know more about EJB3. Great job!
