Review: "Java EE 6 Pocket Guide" by Arun Gupta

This is a review I am very pleased to write. My friend Arun published the Java EE 6 pocket guide and it will be at your hands as early as you can order. I knew about the book quite early, because I had the pleasure to review it and I am thankful for the chance to contribute a little to it! The Kindle edition is already available and the printed books should be available until JavaOne. There is a good chance to have Arun sign it, if you bump into him there!

Abstract

This handy guide provides an overview of the main technologies in the Java EE 6 platform, including extensive easy-to-understand code samples that demonstrate many improvements. Whether you're familiar with Java EE 5 or a Java programmer approaching the enterprise edition for the first time, this book will quickly get you up to speed on Java EE 6. Discover how Java EE 6 provides a simplified developer experience and improves on the developer productivity features introduced in Java EE 5.

The Content
204 pages is a good size for a pocket guide. It covers the basics you need to know of Java EE 6 and gives good examples of all relevant parts. Chapter 1  introduces you to the Java Enterprise Edition in general. Chapter 2 follows with a brief introduction to Managed Beans and their overall life-cycle. Chapter 3 dives into Servlets and all relevant parts. Chapter 4 introduces the Java Persistence API beginning with Entities and the surrounding happenings. Chapter 5 dedicates content around the Enterprise JavaBeans specification. Thins includes Stateful, Stateless, Singleton and Message-Driven up to the Embeddable API and the EJBLite specification. Chapter 6 is about Contexts and Dependency Injection including the portable extensions. The Chapter 7 covers JavaServer Faces very briefly and introduces you to the main concepts. Chapters 8 and 9 are about SOAP-Based Web Services and RESTful Web Services with simple and understandable examples. Chapter 10 covers the Java Message Service with a message send example. The book closes with  Chapter 11 about Bean Validation and how it integrates with JPA and JSF.

Writing and Style
This is a pocket guide which is comprehensively written. I could follow all examples and it was a good read overall. No complicated constructs and clear writing. Walking from chapter to chapter works, but it isn't designed like that. It is more like a reference book to look up the most important topics in Java EE 6 at one point. It isn't watered-down by complex examples and sticks to the most important characteristics of the covered specifications. If you ever have seen one of Arun's presentations or tutorials you know that he is good in explaining things and this style found the way into the guide.


Conclusion and recommendation
I'm obviously not neutral here :) GO GET IT! It is the only book you probably will need about Java EE 6! It is comprehensive, wonderfully written and covers everything you need in your daily work. It is not a complete reference but provides a great shortcut to the things you need to know. To me it is a good beginners guide and also works as a companion for advanced users. Get it while it's hot! Thanks Arun for sharing your knowledge!
