Pro JPA 2 introduces, explains, and demonstrates how to use the Java Persistence API (JPA). JPA provides Java developers with both the knowledge and insight needed to write Java applications that access relational databases through JPA.
Authors Mike Keith and Merrick Schincariol take a hands–on approach to teaching by giving examples to illustrate each concept of the API and showing how it is used in practice.
All of the examples use a common model from an overriding sample application, giving readers a context from which to start and helping them to understand the examples within an already familiar domain.
After completing the book, you will have a full understanding and be able to successfully code applications using JPA. The book also serves as a reference guide during initial and later JPA application experiences.
Hands-on examples for all the aspects of the JPA specification, based on the reference implementation of this specification
A special section on migration to JPA
Expert insight about various aspects of the API and when they are useful
Portability hints to provide increased awareness of the potential for non–portable JPA code
What you’ll learn
Get started with enterprise applications using JPA 2
Get up to speed with object–relational mapping and Entity Manager
Learn and use queries and the query language (JP QL)
Use XML mapping files and learn other advanced techniques
Package and deploy your Java persistence applications
Test your Java persistence applications
Migrate your Java persistence applications
Who this book is for
The book generally targets enterprise and persistence developers who fall in one of three categories:
Those who are new to persistence; we will present some background information and introduce these readers to the basic persistence concepts to bring them up to speed.
Those who know and/or use existing ORM persistence products such as Hibernate or TopLink.
Those who have already used JPA and want to learn about newer features introduced by JPA 2, or have a good reference book to consult when they develop JPA applications.
In general, we assume that the reader is knowledgeable with Java, SQL, and JDBC, and has a little knowledge of J2EE.

What I liked about the book. It covers the topic in a fair degree of detail and is well written. If you're trying to learn JPA I would recommend a book that covers the topic in depth rather than a few chapter in a book on J2EE in general or EJB's. If this is your first exposure to JPA, you should be able to read the first few chapters and come back to the advanced material as necessary. The examples, I feel, are clear and consistent. All in all, a good book if you're learning JPA. If a friend or co-worker wanted to learn JPA, I would definitely recommend this book.
What I did not like is a fairly minor issue. I wish the author had done a better job of highlighting what was new in JPA 2.0. There are applications and developers using JPA 1.0 and it would be nice to highlight some of the differences. If you're working in a JPA 1.0 environment, just be aware that some things covered in the book will not apply. However, since JPA 2.0 is largely evolutionary - 90% of...
With mixed feelings I'm writing the book review of "Pro JPA 2: Mastering the Java Persistence API" by Mike Keith and Merrick Schincariol (Apress, December 2009). On the one hand I'd highly recommend the book to anyone who is interested in the JPA 2.0 specification and doesn't anticipate reading more than a single book about JPA (to have a complete understanding of the subject), but on the other hand it is a book that takes ages to read and even more to digest. It was beginning to try my patience yet I couldn't stop reading it. The more I delved in the book the more 'Aha'-moments struck me.
I first thought I was well prepared for the book and I knew quite a lot about JPA 1.0 in theory and practice, but it took me just a few chapters to realize that I had just scratched the surface of the JPA specification and I'd still dare to call it an extensive JPA knowledge. I couldn't have been wrong more. I had no doubts that the JPA 2.0 was quite new to me with its Criteria API and...
I want to thank the Authors of this book for their great work. I strongly recommend this book to all the developers who want to embrace Java Persistence. It is a pleasure to read this book ang dive deep into the Java Persistence technology.
