The donated source code will be the core persistence engine of BEA Weblogic Server, IBM WebSphere, and the Geronimo Application Server. In May 2007, OpenJPA graduated from the incubator to a top-level project and also passed Sun's Technology Compatibility Kit compliant with the Java Persistence API.
BEA Systems acquired SolarMetric in 2005, where Kodo was expanded to be an implementation of both the JDO (JSR 12) and JPA (JSR 220) specifications. In 2006, BEA donated a large part of the Kodo source code to the Apache Software Foundation under the name OpenJPA.
