    With a Java EE 5 container, you get JPA 1.0 (specified in the JSR 220 – Enterprise JavaBeans, Version 3.0).

    With a Java EE 6 container, you get JPA 2.0 (specified in the JSR 317: Java Persistence 2.0 which is now dedicated).

    And if you are providing your own JPA implementation, well, it depends on the implementation and the version you provide 🙂

    Here are some JPA 2.0 implementations and their respective versions:

    • EclipseLink 2.0+
    • Hibernate EntityManager 3.5+
    • OpenJPA 2.0+
    • DataNucleus 2.1.0+
