Professional EJB

I picked this up last summer as it was the only book at the time offering coverage of EJB 2.0.In the tradition of Wrox books, it offers good coverage of the entire EJB API. While some topics weren't covered exhaustively, that is not what these books are for. This book does provide *effective* coverage of almost everything in EJB 2.0. There is also coverage of design, which is a nice addition!It is GREAT for it's intended purpose. Highly recommended...

This is one of the best books I've read in a long time. It is extremely detailed, clearly written, and well organized. If you're looking for a brief introduction to EJBs, this is probably not your best choice. But, if you want a thorough coverage of EJBs, this is a great choice. The book even covers EJB 2.0 which is not yet covered in most books.

This book does cover EJB2.0 extensively (the review below must be for a different book!). It not only covers the differences between 1.1 and 2.0 but it gives great illustrative examples.Although I have been working with EJB for sometime, the book covers the topics that I don't have time to play around with - it provides very good coverage of topics such as Local interfaces and their uses, EjbQL, and home methods (finally!)The only chapters 19-21 are the only ones that do not go into real depth - but they shouldn't since they relate to topics not necessarily meant for this book; however, they give a great examples to start from such as the wireless one.I definitely recommend this book - I already have to the rest of my team!

This is really one of the most practical books out there in the market. After giving an initial introduction/code examples to basic EJB development, the book slowly progresses to the real stuff like EJB2.0, Design Strategies, UML Modelling, Web Services, Wireless, etc. Each of the topics are thought out and covered well.One particular area that this book would beat out everyone else is in the examples. Almost all the chapters contain very practical code examples.This is not one of those EJB books that explains the theory with some simple examples.. it goes much more beyond that.Programmers are going to love this one.

DISCLAIMER: I am also a tech reviewer, but trust me my intention is to provide an un-biased review here.Let me start by sharing a secret: since January I have been eagerly awaiting the arrival of the 2nd Ed. of Ed Roman's hugely popular EJB book. Well, guess what: while Ed's book is going through community review at theServerside.com (I applaud Ed for being the first to do this, although it may or may not have slowed down the publication process), Wrox managed to go a leg up and became the first publisher of an EJB 2.0 book. Judging from the content of the current book, I have good reasons to say that it has raised the bar for the next generation of EJB titles coming out in the 2nd half of this year. Why? For one thing this book is based on the new EJB 2.0 spec and is up-to-date with PFD 2. As if this not enough a selling point by itself, Wrox also threw in a bunch of other high-octane topics, which made the total value proposition very compelling. Let's now go through the content of the book, should we?Chapters 1 to 4 mostly target EJB newcomers. Here you find short and sweet code samples for each flavor of EJB 1.1 session and entity beans. The author's emphasis is clearly on the client views and life cycles of these beans. Many state and sequence diagrams are used to help readers to come to a good grip of this critical material. I consider the goal superbly achieved, even though the code could have used some System.out.println calls to demo actually how bean classes are invoked by an EJB container. Well, save that as your homework.Chapters 5 and 6 cover the new EJB 2.0 entity bean features we all have been waiting for, i.e., local interfaces, container-managed relationships, home methods, and EJB QL, among others. Dan O'Connor was at his best again explaining how the new spec solves some of EJB 1.1's toughest problems, like the need to use coarse-grained beans to cut down the number of remote calls. Experienced EJB developers, start here.Chapter 7 introduces MDB. Frankly, I would like to see it augmented to include more details on transactional MDB. Well, Tyler Jewell should fill that void in Ed's book.Chapter 8 deals with EJB environment, an often-confusing topic to many. How do I specify a DataSource in my ejb-jar.xml file? What does "java:comp/env/..." mean and where does it come from? You get the answers here.Chapters 9 and 10 are about EJB transactions and Security. And let me tell you - read these vital topics here and forget about any other book. The discussion is so much better in breadth and depth than anywhere else. You need an example on a distributed TX? No problem. Want to understand security principals? They have it covered.Chapter 11 starts a section on EJB design issues by providing some well-thought-out advice. The topics are so timely and relevant, like bean granularity, session vs. entity beans, BMP vs. CMP, which people ask on a daily basis at various EJB forums. EJB architect wanna-be's: read this c
