Java Persistence with Hibernate
Second Edition of Hibernate in Action
...this book is the ultimate solution. If you are going to use Hibernate in your application, you have no other choice, go rush to the store and get this book.
Java Persistence with Hibernate explores Hibernate by developing an application that ties together hundreds of individual examples. You'll immediately dig into the rich programming model of Hibernate 3.2 and Java Persistence, working through queries, fetching strategies, caching, transactions, conversations, and more. You'll also appreciate the well-illustrated discussion of best practices in database design, object/relational mapping, and optimization techniques.
In this revised edition of Manning's bestselling Hibernate in Action, authors Christian Bauer and Gavin King—the founder of the Hibernate project—cover Hibernate 3.2 in detail along with the EJB 3.0 and Java Persistence 1.0 standards.
The book ends with detailed coverage of JBoss Seam, a revolutionary web application framework for Java EE that builds on EJB 3.0, JavaServer Faces, and Hibernate concepts.

About the Technology
Persistence—the ability of data to outlive an instance of a program—is central to modern applications. Hibernate, the most popular Java persistence tool, provides automatic and transparent object/relational mapping so it's a snap to work with SQL databases in Java applications. Hibernate conforms to the new EJB 3.0 and Java Persistence 1.0 standards.
What's inside
- O/R mapping concepts
- Get started with Hibernate and Java Persistence
- Efficient database application design
- Comprehensive Hibernate and Java Persistence reference
- Unmatched breadth and depth

"Java Persistence with Hibernate" is the most comprehensive, authoritative and definitive guide, tutorial, and reference to OR-mapped Java persistence.
A definitive source on Hibernate. Great for any developer.
I wholeheartedly recommend this book!
Great topic, great content, and there is a great need for this book!
...very thorough, very complete. I highly recommend it.
A must-read for developers using Hibernate.
It's the best book out there about Hibernate (and there are quite a few on the market right now), maybe even the best book about ORM in Java, in general.
