JPOX is a heterogenous persistence solution for Java. It allows you and your team to take your Java data model objects and persist them to a datastore without having to spend large amounts of time defining how they will be persisted. This means that you can concentrate your application development time on adding business logic rather than the routine task of storing/retrieval of your objects.

JPOX is designed to comply with all pertinent standards in the persistence domain. It is a fully compliant implementation of the JDO1/JDO2 specifications, and complies with the JPA1 and JDO2.1 specifications in its 1.2 release. This means that by choosing JPOX you have persistence behaviour that you can trust and is defined in Java standards specifications. In addition JPOX is extensible utilising the OSGi standard plugin mechanism and providing many extension points where you can enhance your persistence capabilities even further. JPOX is free and released under the Apache 2 open source license, and so the source code is available for download along with the leading open source standards-compliant Java persistence implementation.
