Rating:  - Most Practical J2EE Book I've Read Yet...
I never taken the time to write a book review on Amazon.Com before, but after purchasing this book, I thought I should. This is the most practical book I've read yet on developing J2EE applications. As a J2EE application architect, I must say it addresses all the issues I've encountered over the past several years. I wish this book would have existed a couple of years ago (so I wouldn't have had to learn the hard way). The book really focuses on doing what's practical and discourages over engineering due to J2EE hype. The book is very current and discusses many of the widely used open-source products -- something I'm a big proponent of. In my mind, this book should be considered the "J2EE Bible". Lastly, you don't have to be an application architect to understand this book. It's very easy to read -- obviously intended for J2EE developers at all levels. I'd give this book 6 stars if I could.
Rating: - Java Developer
In my opinion, this is a very practical, resourceful and insightful guide -- as it explains J2EE Technologies from the point of view of their applicability.
It discusses the issue, proposes a solution and also provides alternative approaches to solving a given design problem.
This book provides vital information for J2EE Architects and Lead Developers by showing how to avoid making mistakes that have critical impact on design and implementation of enterprise Java software.
Rod Johnson writes in a clear style, which makes this book very interesting and inspiring to read.
Rating: - A book on solutions, not specifications
The real differentiator of this book is that its focus is on how to use J2EE to solve real-world problems, rather than providing an overview of the J2EE specification itself. As such, it's a much more pragmatic approach to using J2EE than the other books I've read on the subject.
The author starts by taking high-level perspective on the subject, showing the different design considerations that need to be applied when choosing which J2EE technologies to use. A case study (a ticket booking system) is described and elaborated on throughout the book, showing how these design considerations affect a real-world solution.
The book also provides a load of coding tips I found useful, from better use of reflection, to judicious use of design patterns, to how to minimise your refactoring. The author assumes the reader is an experienced developer, so doesn't focus on rudimentary Java and architecture. I found this useful, but it means the book is more focussed to a specific audience.
Amazingly, the book also provides an entire framework based on J2EE on which you can put your application logic. My only complaint is that this is not included in a companion CD - you have to download it.
Overall, the book works because it shows you how build solutions, not just understand the technology.
Rating: - Great Book
This is a definite must have for any serious J2EE Developers.
The book does not deal with the mechanics of the different J2EE technologies. There are plenty of books on this topic.
This book is different then all the other books on J2EE because it really does focus on the best practices associated with building J2EE applications. The two chapters on J2EE data access was particularly well laid out.
Overall a good book and worth the money spent on it.
