Apache OpenJPA comes in two separate branches, each production level material.

The differences between the two are the standards they implement. The 1.x branch follows the JSR-220 Enterprise Java Beans 3.0 specificationm while the 2.x branch was modeled after the JSR-317 Java Persistence 2.0 specification.

OpenJPA works out of the box as a persistence layer for Spring and Tomcat applications, but developers can also build it as a standalone Java library, even working in non-Java EE mediums.

A Java persistence project that can be used as a stand-alone POJO persistence layer or integrated into any Java EE compliant container and many other lightweight frameworks.
