It is obvious that much editing went into this book. It is clear, concise, and contains few errors. Although it is 'short' compared to other technical tomes, it does not short-change the topic covered. I wish all technical books were of this quality.

This book provides an excellent overview to what Enterprise JavaBeans are and then goes into details on how to use them. If all you need is an high-level understanding of EJBs, chapters 1-3 are for you. If you will be developing EJBs read chapters 1-9.

You do need prior experience with Java and JDBC to get the most out of the examples. The provided diagrams are effective, I just would have liked seeing a few more at the point when new concepts are being presented.

This will be a book I will continue to reference as I develop EJBs.

I am currently working on a large Internet application project using Application server with EJB and was looking for "the" EJB book. And I found O'Reilly's Enterprise JavaBeans by Richard Monson. The book is already being well talked amongst EJB developers and a leading resource to EJB community. As a feather to the cap, this book is recommended in our corporate training session on application server being provided by Netscape.

The key plus point of the book is that it covers both development concepts as well as behind the scene issues which provides clear understanding of EJB and its development.

Chapter 1 talks about various concepts of CTM and Server side component model and gives good insight about distributed object architecture. Chapter 2 explains the EJB architecture from the developer's point of view. But the author has also explained the role of EJB container. Chapter 3 gives an excellent overview of various primary services and also resource management issues. This includes the concepts of transaction, persistence, Naming, Security, Instance pooling etc.

Chapter 4 and 5 takes through the steps required to develop server side as well as client side codes. Moreover the cruise line illustration is quite simple and easy to understand. Chapter 6 and 7 explains the life cycle of Entity and session beans clearly explaining the concepts of bean-managed and container-managed persistence and stateful and stateless session beans. The key concepts are well represented through suitable diagrams. Chapter 8 gives detailed insight to various issues related to transaction management including Declarative transaction, Isolation, Explicit transaction management etc. Especially, all the transaction attributes are represented through flow charts for easy and thorough understanding.

Last and most important chapter discusses design strategies, which is the crux of any EJB based application development. It explains the issues to be considered during the design of the componentization model including Passing objects by values, Object to relational mapping tools, Implementing a common interface etc.

A 'must' to all EJB developers.

Easy to understand in depth no nonsence coverage of EJB 1.0 - BUT you would better of buying the new second edition that covers EJB 1.1!

A very thorough grounding in EJB. This book can be carried (it's only 320 pages) and still manages to get all of the key concepts across. It builds up the reader's knowledge by starting at a high level and then getting deeper as the book goes on, with detailed explanations of the sample code. You can try out the samples yourself but just reading the book provides a good EJB education. Strongly recommended.

Upon first reading this book, I didn't know to think little of it. Then I took reading other EJB books and found this one wanting for the following reasons: Entity Beans are described prior to describing Session Beans (when Entity Beans can be likened to specialized Stateful Session Beans), at no time did the book clearly and concisely state the bare minimum necessary to implement a Entity and Session Beans, and the book seemed to assume prior knowledge of other Java technologies such as JNDI and RMI.

As I stated above, there are other books out there (that I will not name as I believe that I had a review censored for naming a book) that more clearly delineate what an EJB developer needs to know to hit the ground running. Look elsewhere.

I've read the book cover to cover and found it an excellent description of both the "hows" and more importantly the "whys" of EJB. It helped move me from the buzz-word/magazine article knowledge level to a thorough understanding of the technology -- including its current shortcomings.

I am working on an EJB project and and affiliated with several others. There are five or six copies of the book floating around and we need more because we (the architects and developers, not the managers) keep borrowing them back and forth.

I just finished reading this book today. As a member of the EJB community and an author myself, I can confidently say that Richard has done a superb job on this book. My favorite parts are when he goes into how stubs/skeletons work in chapter 1, his section on design strategies, and his accompanying web site. I commend Richard for his great work, and would recommend this book to anyone interested in quickly ramping up on how EJB really works.

This book isn't a bad introduction to the topic. However if your looking for depth I would suggest you look elsewhere. For senior developers looking to tackle real world problems their's not enough here to really get you going.

If you really want to "MASTER" EJB then buy 'Mastering Enterprise JavaBeans' by Ed Roman. Its a lot better with complete REAL world examples (there are 13 commercial level beans included with the book). The O'Reilly book does not explain the concepts clearly and is also lacking in examples. Ed Romans' book is the best book on EJB you can find on the market and is truely a masterpiece. If you are going to uy just one EJB book I would recomment Ed Roman's book. It also covers advanced topics like RMI over IIOP...

I just wanted to say that I found this to be good book on Enterprise Java Beans (EJB). I am currently using this book to write a few applications and found it to be useful. This is definitely not a place for JDBC reference. I don't understand why people are complaining about this book not covering JDBC.

The author covers the fundamental concepts of EJBs very much without getting bogged down with proprietary information.

I definitely recommend this book. I only thing I regret is the lack of a CD rom with the code examples. Right now, I am having to type all the code.
