EJB 3.0 sets a precedent. It has made huge advances in ease of development, and its drastically simplified programming model has been widely acclaimed.

Mike Keith, EJB 3.0 co-specification lead, and Merrick Schinariol, reviewer of EJB 3.0, offer unparalleled insight and expertise on the EJB 3.0 persistence specification, in this definitive guide to EJB 3.0 persistence technology. Expect full coverage and examination of the EJB 3.0 spec from these expert authors, including:

The EntityManager API
The new features of EJB Query Language (EJB QL)
Basic and advanced object-relational mapping
Advanced topics like concurrency, locking, inheritance, and polymorphism

Assuming a basic knowledge of Java, SQL, JDBC, and some J2EE experience, Keith and Schinariol will teach you EJB 3.0 persistence from the ground up. After reading it, you will have an in-depth understanding of the EJB 3.0 persistence API and how to use it in your applications.

Industry Reviews

From the reviews:

"An introduction to the new Java Persistence application programming interfaces (APIs), this book serves not only as a tutorial on how to use them, but also as a basic reference text. ... The book is very well written, and the technical material is presented clearly without excessive detail. ... this is an excellent textbook." (M. S. Joy, ACM Computing Reviews, Vol. 49 (3), March, 2008)
