There are two obvious changes between this second edition and the first edition of this book. First, some new patterns have been added mostly dealing with web services. Second, the book has been released as a hard cover book, presumably because the publisher expects this to last on your shelf as long as the original "Design Pattern" book. The new patterns dealing with web services are a welcome addition to the book although anyone who is interested in this subject will probably want more detail such as found in Paul Monday's book.

Part 1 is an introduction to design patterns and the J2EE platform followed by a catalog of design considerations, bad practices and refactorings. Developers working with poorly designed J2EE applications will find this section especially helpful.

Part 2 is the collection of the design patterns and strategies. Each pattern is described in the expected level of detail. The format will remind you of the GoF book. Since this has become the standard format for presenting design patterns this should not be a surprise. The patterns are well thought, explained clearly, and demonstrated with some good code samples. If you have the first edition you will be very impressed with the improvements made in this new edition. It appears that virtually every pattern has been reworked to make the pattern easier to understand and use.

This is the book that every J2EE architect and programmer should have on their desk. Using the strategies in this book will make your applications more robust, make you more productive, and make your code easier to understand and maintain. Anyone designing, architecting, or coding with J2EE will find this book to be extremely useful.

Overall Rating: Well done! This book will be a valuable teaching and reference tool.
Teaching Value: Excellent! An essential book on this topic.
Reference Value: A complete reference. I would not need any additional reference on this topic.

The primary focus of the book is on patterns, best practices, design strategies, and proven solutions using the key J2EE technologies including Java Server Pages (JSP), Servlets, Enterprise JavaBeans (EJB) and Java Message Service (JMS) APIs. Written from a programmer's perspective with extensive codes and fully illustrated with UML diagrams.

The book is fully revised and newly documented patterns providing proven solutions for enterprise applications. Material is presented in a logical progression so you can learn at your own pace. And yet there is depth in the book to make this a valuable resource for any professional who knows J2EE and wants to use J2EE to build web services.

The author did a great job describing useful patterns for application architecture and design strategies for the presentation tier, business tier, and integration tier. The section on refactoring is worth reading. This book unites the platform's many technologies and APIs and provides insightful answers to whys, when and hows of the J2EE.

Hi, Already having a number of Core J2EE and Gang of 4 pattern books. But this book I find still the best to understand and follow. Best thing I liked about this book was that this is the first book which captures not only best practices but describes bad practices too. Authors have used very easy to understand examples but without missing the depth of the subject. Great work of writing.
