From the Author
Dear Reader,�When we conceived the original edition of this book in 2006, the lightweight EJB 3 API was still in its early stages, yet it was clear to us that the EJB specification designers had at last achieved the right blend of power and usability. Coming from the EJB 2.x world, it was like a breath of fresh air, and reminded us of how it felt to discover Java technology after years of programming C and C++. Th e EJB component, redefined as an ordinary Java class whose metadata could be declared through Java annotations, and enhanced by the introduction of generics, container injection, and interceptors, became the basis for a much more nimble development model: one that gained elegance through simplicity. Enter the new Java Persistence API (JPA), where entities, too, were recast as lightweight Java classes and O/R mapping metadata could be specified through spec-defined annotations, and we suddenly had a comprehensive enterprise component model comprising the latest technologies, all rolled into a worldwide standard. So you can see what got our buzz going.�Fast forward to now, and the release of the EJB 3.2 and JPA 2.1 specs. Spanning over a thousand pages combined, these specifications have matured to address a number of new areas and improve upon their ease of use. Once again we saw an opportunity to translate this latest material into an approachable format that reads well and makes liberal use of examples that you can build, execute, and further explore on your own machine. In this second edition, accompanying the release of Java EE 7, we introduce the EJB 3.2 and JPA 2.1 APIs along with key features in the CDI and JAX-RS specifications through a series of digestible chapters, allowing you to become comfortable with these technologies one topic at a time. Within each chapter we provide executable source code examples that demonstrate how each feature works, and how the pieces fi t together. So you don't have to swallow the whole enchilada in one humongous gulp. In the spirit of our Apress Wines Online application, which we use for numerous examples throughout the book, we want you to truly savor and appreciate the richness of the Java EE 7 component ecosystem. For each technology we provide straightforward examples, but we also strive to explain when and where to use its features and what their strengths and weakness are, and offer insights into best usage practices. Following these topical explorations, we explain how to integrate EJB and related components into a comprehensive Java EE 7 application, and then turn the spotlight on transaction management, performance analysis, deployment, testing in an Embeddable EJB Container, and how to build solid EJB clients.Our job is to transform you from EJB novice to expert, and we want you to enjoy the ride!�Jonathan Wetherbee, Chirag Rathod, Raghu Kodali, and Peter Zadrozny�Who should read this book?�This book is targeted at enterprise software developers who are experienced with Java, have built single tier or multitier applications using earlier versions of EJB or related technologies, and are looking to build enterprise software based on the latest cross-platform industry standards.�As authors of an introductory-level text, we have two main goals:
- Our first goal is to get you comfortable working with the many essential elements of EJB and several closely related technologies. �We will walk you through the steps required to design, build, deploy, execute, and test comprehensive enterprise applications in a Java EE environment. We expect you to be able to come away with a sense of ease with the nuts and bolts required to build and assemble a variety of applications based on EJB components.
- Our second goal is to provide you with a broad perspective on the service and persistence tiers of Java EE as a whole and, in particular, on the full range of features offered by EJB. We intend for you to leave this book holding a breadth-first foundation that will serve as a launchpad from which to explore specific areas of the EJB and related specifications in greater depth.

Decent coverage with some flaws
By Ammy_Evaluator
This book is intended for beginners wanting to find their way around EJB 3 and Java EE persistence APIs.
That, it does well - providing a high level overview of these technologies which should be sufficient for an initial exploration. Useful examples are also provided based on the GlassFish AS with the NetBeans IDE.
Even better, it does all this within a relatively short number of pages.
My biggest problem with it has to be the inconsistent writing quality. Some chapters are extremely well written (the first 3), and then you hit a brick wall with chapter 4 which contains such tautological assertions as "Within a given entity inheritance hierarchy, a single inheritance strategy applies to all entities in the hierarchy."
Other chapters have similar gems that can leave you scratching your head:
"Also, the restriction that only one persistence context for any given persistence unit must be associated with a given transaction context ensures that for any entity of type T with identity I, its state will be represented by only one persistence context within any transaction context."
Another problem is the striking lack of diagrams - even life cycles are described rather than depicted.
Overall, though, I was pleased with the broad coverage of a variety of topics all in a single (fairly) easy to consume package.

Excellent guide
By john anderson
I was extremely experienced in J2EE and early EJB technology back in 2003/4/5 then left the Java world to work full time in Obj-C. I had a requirement to come back to JEE to design and build a server app under JEE7 and discovered the JEE world had changed significantly. I read the common texts on Java 7 and JEE7 but still did not have my head around practical usage of EJB, JPA, and CDI in the JEE7 world. This book solved that problem for me. I have used Eclipse since it was first released and where books (like this one) use Netbeans for all their examples; I have always reloaded them into Eclipse and smoothed the edges. With this book I took their advice and used Netbeans and found the books guidance made this seamless. All examples are well written, packaged clearly, AND actually work immediately. Over all I this this one of the best technical guide books I have read in a long time (and I read a lot of them!). Well worth reading if you want to get your head around these technologies.

Critique of the Kindle Edition
By Mark Mueller
I wanted to start reading this book right away and decided to give the Kindle edition a try. I agree with the other reviewers that the book itself is well written and covers the topic well. On the other hand, I wish now that I had ordered the print edition instead. Kindle is superb for reading a novel -- the text flows nicely and the font resizes very easily. At this point, I don't think that Kindle is particularly suited to technical books with diagrams and code samples. Some of the diagrams in the book are small and fit very well on the screen. Screen captures are hard to read because they are rendered in shades of gray. Kindle allows you to magnify the size of an image, but only to the size of the screen. Since most of the diagrams are full page width, there is little gain. From the text I generally found that I could guess the unreadable text in the screen captures. Figure 7-4, a domain model showing classes, methods, class relationships is totally unreadable, and this is a case where I think being able to read and understand the diagram is critical. I would say that until Kindle allows you to magnify diagrams well beyond the size of the screen so that you can pan them with a scroll-bar, it's not well suited to books like this.
