Rating: - Complete, but not really usable
This books seems to achieve the goal it has in mind, that of providing the user with the information necessary to use the Java Persistence API. Unfortunately there are real problems in the execution of this book.
A book like this should not only be full of examples, but it should be structured in such a way that it is easy for someone using the book to duplicate the examples on their own system. This book fails to do so.
In chapter two we are promised a complete application ... Read More
Rating: - Excellent!!
This book is a joy to read. Object relational mapping is explained in a very simple manner. What I like about this book is that it explains a certain concept and then immediately talk about the specific use-cases when that concept/design may not be the best choice. The authors then give excellent suggestions and alternatives.
Very good reading material, simple examples used to explain complicated concepts. Writing style of the authors is also very engaging.
A very good buy.
Rating: - Must Read book for JPA
This is the best book out there that explains in detail how JPA works with some good examples. I found the book to be well structured and easy to read.
I would recommend this book for anybody who is looking to work with JPA.
Rating: - Great Reference for JPA
Pro EJB3 is a great book. Having been using it for over last 6 month on my recent project, I can definitely say that this book is invaluable.
Have been worked on EJB 2.x for many years and on several projects with different application servers (Weblogic, JBoss, WebSphere), I understand the basics of EJB. So I want not only understand the basic how-to in EJB3 and JPA, but also want to understand the in depth explanations on transaction, persistence context and different behavior in the new system. ...

Rating: - Company decided against using EJB 3.0
Anything that requires getting a bunch of jars on the server classpath was deemed unsuitable for automated deployments. I wonder how people manage automated deployments and configurations, especially in a multi-server clustered environment.
