Java Persistence API
Apache OpenJPA 2.0.0 Released
Apache OpenJPA version 2.0.0 is now available.
This distribution is a fully compliant implementation of the Java Persistence API, version 2.0 specification, and passes the JPA 2.0 TCK. It can be used as a stand-alone POJO persistence layer or integrated into a Java EE compliant container, or a framework such as Tomcat or Spring.
This release addresses some backwards compatibility issues, and adds JPQL tests for element collection, detach processing, and new tests for query qualified paths. OpenJPA decouples the QueryCache from the DataCache, and invokes MetaModel generator. See the Release Notes for a full list of updates.
