Summary: Great help in EJB design
Review: This is a really great book, which I would like to recommend to anyone working with software development related to EJB's or J2EE. Anyone who would like to learn about the concepts could also read it since it covers all levels of understanding from the overall picture to the nitty-gritty details of anything related to EJB.
What I found most helpful were the parts about best-practice solutions, which guided me a lot in my design decisions.
Even better, if you can accept reading the book on your computer screen, as a pdf file, it's free of charge.
Thanx for a great book Ed!!!

Summary: The best computer book ever read
Review: This is the easiest to understand, best organized, most interesting to read computer book I have ever read in my life. I read the review of this book and download the free pdf version of this book. I was thinking that I will make my decision to buy this book after I finish reading it. However, as I finished reading the first chapter, I had already felt so excited for this book that I couldn't wait to own it myself. The main point I want to stress is that Ed Roman is really good author/instructor. I had understand more about EJB after reading the first chapter than after reading the entire other EJB books.

Summary: An Excellent books for those who wish t know about EJBs.
Review: Ed Roman has done a wonderful job in writing this book. He has taken lots of pain to describe every concept in detail. This book (and it's previous edition) has managed to explain me everything I wanted to know about EJBs. I recommened this book to everyone.
In fact, this book can also be downloaded for preview. It was only when I read the pdf version that I decided to buy this book. I surely saved a lot of time, money and efforts for researching a good book on EJBs. Meghraj.

Summary: Great book
Review: Awesome book, extremely well-written. Highly recommended.
Srinivas is incorrect in his review of the example in Ch 4. I used BEA for the test cases also, and the following weblogic-ejb-jar.xml deploys their bean exactly as specified. The book leaves the deployment up to the reader for your particular container, so if you need help here, just consult your app server documentation...

Summary: Good book but not for starters!
Review: This book states on the back cover: "All you need to know to get started with this book is Java". What does this mean? My first guess was OK, I have done some Java programming in the past so this book will get me going in EJBs. How far from the truth this was. I would sugest anyone to get a gentler introduction (book) if they want to understand this book. The two tutorials at the back on RMI-IIOP & JNDI are not tutorials, they are summary notes on advanced topic(s).

Summary: Hardcore Enterprise Java Beans...
Review: I browsed through various books on EJB's, and as expected, they all contain the same concepts and diagrams, as they are all based on the same J2EE specs; while some of them delved into the intricacies of a certain Application Servers(BEA's or IBM's), and other were Application Server independant, this book STANDS OUT between all of them. This is a "HARDCORE" book on EJB's, it goes into the deepest details regarding EJB design like Clustering and Transaction issues while avoiding the pitfall of detailing a certain Application Server.It also has great introductory tutorials on other EJB issues like JNDI and CORBA-IIOP, where other books seem to fall short. The other subject I found especially helpful was the best practices section, this shows that the authors have "on-hands" knowledge of builing EJB Systems, and gives you some incite on difficult to grasp concepts. All in all, this book is centered on "the issues", not the hype or Application Server.

Summary: Well-written book, with misleading info.
Review: It is well-written, but does have gotchas. I read until chapter 4 and already stumbled on a non-trival error. Chapter 4 of the book illustrates the passivation/activation of SFSB with code (that explicitly states to run on Weblogic 6.1) But there is just no guaranteed way to FORCE a container to invoke ejbActivate()/ejbPassivate() calls. Book says so, on page 86, line#11: "It's up to the container to decide when passivation makes sense". I tried the code as it is, and even with various other deployment-descriptor settings on the recommended Weblogic 6.1 and just cannot get the container to generate the server-log showing passivate/activate calls like shown on book's page#99. The code and the server-log is certainly misleading to the reader giving an impression that we can code in such a way to make the container invoke activate()/passivate() calls, when in reality we just don't! Furthermore, the author(s) say they don't have time to address/respond to this glaring error, even when pointed! Take away point: Just because it is well-written doesn't mean it is all correct. And I hope J2EE spec addresses this hole, because no matter what code you have in ejbActivate()/ejbPassivate() methods, currently there is no way to write test-cases to test that!

Summary: very good writing
Review: I rarely have such strong feelings toward a CS book. But this one striked me as one of the best I've read. It explained many of the hard-to-grasp java topics, such as RMI-IIOP,JNDI,object serialization and so on in very clear to understand words. I think if you are a beginner on EJB, this is THE book you should get to get a fast start; it really helps you grasp the concept solid and strong. I recommend it to everyone who is studying EJB. Cheers.
