Thoroughly enhanced for the EJB 1.1 specification, Enterprise JavaBeans, 2nd Edition provides a great introduction to the world of server-side Java components. With plenty of material on EJB architecture and design, this new edition can serve as an authoritative resource for mastering today's bean standards.

Besides a general introduction to EJBs, the new edition of this book excels at highlighting the differences between the EJB 1.0 and 1.1 standards. Sample code is provided for both versions. For deployment, EJB 1.1 now relies on XML to define all bean resources and dependencies. For every sample bean, the author provides the XML, as well as the old-style Java code for EJB 1.0. There's also plenty of coverage of the new reliance on JNDI (the Java directory service) in EJB 1.1 and other late-breaking Sun standards, such as combining EJBs with servlets and JSPs for delivering dynamic Web content.

This text is organized as a tutorial to the major types of EJBs with full coverage of entity beans (for accessing databases) and session beans (for managing "conversations" with particular clients). The author covers all the bases here with numerous diagrams describing the life cycle of beans and how they cooperate with today's application servers. As in the first edition, sample beans for a cruise ship booking application let you see actual EJB code in action. Helpful appendices list all EJB APIs and other useful information (such as a list of current EJB vendors).

In all, the revised edition of Enterprise JavaBeans shows off the considerable strengths of the new EJB 1.1 standard. Suitable for any working Java programmer or IT manager, the clear presentation of the strategies and techniques for successful component design help make this book a smart choice for successful development with EJBs. --Richard Dragan

An excellent introduction to the subject of EB.

WOW! Being just vaguely familiar with the EJB specification. I was looking for a good introduction with some decent examples. This book has provided both.

Horribly Writen, useless information
I buy discount software books whenever I can, and I picked this up for 8 or 9 bucks somewhere. Man, what a waste. I learned more about EJB from SUN's website and from reading on the internet. The examples were useless, and the chapters were disjointed.

great!!!
This book was my first exposure to EJB/J2EE and I have found it to be very helpfull. I have read it from cover to cover and I am about to use the knowledge I obtained to rewrite our existing thick client to a JBoss client/server.

I strongly recommend this book.

Not for beginners...
This is a very well designed and written book covering EJB technology in a complete and in-depth manner. There's a quick intro to the subject, and then the rest of the book builds on that knowledge in tutorial fashion. You will build a cruise reservation system using beans, and in the process you'll learn a lot. It does assume that you have a solid foundation in Java skills before you dive in, so don't get this book unless you're already well on your way to learning Java. It's not for beginners.

Another very nice feature is the companion workbook that you can buy for this book. It translates many of the exercises into more specific instructions for running them on the Websphere platform. This is an extremely valuable addition to the learning process. All too often, a writer has to assume a certain platform or system to be able to cover the material. If you also use that same system, you're OK. If you're not using what the author had, then there can be a translation process that can be frustrating at times. Having a workbook focused on your specific platform will speed up the learning and avoid the hassles involved in debugging your errors.

If you're a Domino developer just getting into Java and J2EE technology, hold off on this book. While you may well get to this point in your career sometime in the future, it will be of little use to you right now. There isn't much that is applicable to the pure Domino world, and you'll need to be very well grounded in the Websphere world before this will start to gel for you.

Conclusion
I would recommend this book to a good Java developer needing to learn EJB technology for their jobs. It's very complete and comprehensive. If you're just trying to get started in Java, this book is still aways off for you. I was pretty well lost through most of it, so I need to come back to it in a year or so once I have some more experience.
