Book recommendation for Hibernate?

Question

What book/article do you recommend for learning hibernate?

Answer 1

Java Persistence With Hibernate is quite in-depth and complete, containing quite a bit of sample code as well.

A good rule of thumb is to use the more generic JPA APIs when possible, and use specific Hibernate calls where necessary.

Answer 2

I used the Hibernate online documentation. Really! :-)

Answer 3

The Official Tutorial and documentation is a great reference for learning Hibernate.
