Amazon.com Review

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

Product Description

Enterprise JavaBeans was recently voted "Best Java Book" by the editors and readers of Java Developer's Journal. Readers of JavaPro named it the "Best Java Book for Experts." And Amazon.com included it in the Top Computer Books for 2000. Now the best only gets better! In the new 3rd edition, Enterprise JavaBeans has been completely revised and updated with a thorough introduction to the new 2.0 version of the EJB specification. Significantly different from the earlier version, the 2.0 specification introduces three dramatic improvements: A completely new version of container-managed persistence; local interfaces; and a totally new kind of bean called the "message driven bean." Enterprise JavaBeans, 3rd edition, provides a thorough discussion of these changes, along with an architecture overview, information on resource management and primary services, design strategies, and XML deployment descriptors.

5.0 out of 5 stars Good to the last drop!, April 18, 2000

By	David Holts (CA) - See all my reviews

This review is from: Enterprise JavaBeans (Java Series) (Paperback)

I thoroughly enjoyed this book. Every chapter was excellent.

The book starts with a chapter that explains distributed objects, components, server-side components, and transaction monitors in a way that makes total sense and is fun to read.

The next couple of chapters give you an in-depth look at the EJB architecture removing all the mystery from the technology -- these chapters are pure gold.

Chapters 3 through 7 show how to develop stateless, stateful, CMP and BMP entity beans. These chapters explain how to write beans and how to use them. The examples are very excellent.

Chapter 8 is a very long but necessary chapter on transactions and how they work in EJB. I'm glad they saved this for after Chapters 3 -7 because it's complicated.

Chapter 9 is a priceless Design Strategies chapter that gives you more punch in the first 10 pages then most books give in 100. Even experienced EJB developers will learn new tricks from this chapter.

Chapter 10 is on XML deployment descriptors. This is an excellent reference and the way its organized makes it much simpler to understand.

Chapter 11 covers J2EE. It's short but excellent. The author tells you exactly how EJB fits into J2EE, which is all I wanted to know.

Appendix A - D are an invaluable reference for developers. They include a complete class reference, UML state diagrams and charts, vendor listing and finally a summary of the changes from EJB 1.0 to EJB 1.1.

This is the best EJB book available and will continue to be the best for a long time. Its too solid and too well organized not to be.

5.0 out of 5 stars The best EJB book, April 19, 2000

By	Walter Greenspan (Boston, Massachusetts) - See all my reviews

This review is from: Enterprise JavaBeans (Java Series) (Paperback)

I've read two EJB books and this is, by far, the best one. I started with Ed Romans book, which I never finished because I quickly realized the author knows very little about distributed computing. I found refuge in the Monson-Haefel book, which I found to be concise, detailed, and extremely well written. Richard Monson-Haefel is man who obviously knows his business. The book starts out with a basic chapter on distributed computing. I didn't need it, but it was probably the best introduction to the subject I've ever read. Novices will love it. The rest of the book gives you a unique insight to the inner workings of EJB servers while keeping the language straightforward so that everyone can understand it. Everything is covered including entity, session, transactions, and J2EE. I give this book my highest recommendation.

5.0 out of 5 stars Required reading, September 29, 2000

By	David Washington (Boston, Massachusetts) - See all my reviews

This review is from: Enterprise JavaBeans (Java Series) (Paperback)

We have been using this book on a large EJB project and have been very happy with it. Monson-Haefel addresses the most complex parts of the EJB platform with a style that makes the book enjoyable to read and EJB fairly easy to learn.

The first three chapters of the book explain the purpose, architecture, and implementation of EJB servers. This really helps our people to understand what was going on under the hood and why beans behave the way they do. Without this material, EJB would be a mysterious black box. We now understand EJB at it lowest levels, which makes our people more productive.

The rest of the book provides a detailed explanation of how to develop each kind of bean (stateless, stateful, and entity beans) using an example application. As the book proceeds it builds on the example increasing the complexity incrementally. What's especially appealing is that example is not so large that it's distracting. The book is very focused and the examples add rather then detract from the book.

One of the books greatest strengths is the way it covers Enterprise JavaBeans in detail. Chapter 8, for example, goes into detail about transactions, database locking, isolation levels, and how transactions are propagated. In addition, the same chapter explains how exceptions impact transactions -- a very real issue when developing large-scale projects.

There is also a great chapter on "design strategies" which introduces ideas like the business interface and bulk accessors. While these designs strategies are invaluable to our project, we would like to see a lot more of them. In particular a section on design patterns in EJB would be very helpful. Hopefully this kind of material will be added in a future edition.

EJB is fairly complex, so a good book like this one is a gold mine. We now have about 20 developers working on our EJB project. Every time we add a developer to our project, they are handed a new copy of this book and told to read it. Without out this book most of our new developers would be hopelessly lost. If you are going to use EJB in your project, then you absolutely must have this book -- its essential.
