1.2. Java Persistence API (JPA)

The Java Persistence API (JPA) is the standard for using persistence in Java projects. Java EE 6 applications use the Java Persistence 2.0 specification, documented here: http://www.jcp.org/en/jsr/detail?id=317.

Hibernate EntityManager implements the programming interfaces and life-cycle rules defined by the specification. It provides the JBoss Enterprise Web Server with a complete Java Persistence solution.
