Pax JPA
An OSGi JPA Service Implementation
Features
- Pax JPA implements the OSGi JPA Service according to the OSGi Enterprise Release 5 specification. (The JPA chapter is still at version 1.0 and thus unchanged from earlier specification releases.)
- Pax JPA provides a generic extender which registers an
EntityManagerFactoryBuilderservice on behalf of any JPA 2.0 or 2.1 provider with an OSGi manifest. This is just a small add-on on top of Eclipselink, OpenJPA or Hibernate. - Pax JPA supports load-time enhancement of entity classes.
- Pax JPA supports JNDI names for data sources, avoid hard-coded connection properties in the persistence unit descriptor.

As usual, Pax JPA artifacts are available from Maven Central.
Changes since 0.1.0
Pax JPA is a new OPS4J community project which implements the OSGi JPA Service specification.
The implementation is based on a generic extender which registers an EntityManagerFactoryBuilder service on behalf of any JPA 2.0 provider with an OSGi manifest. This approach works with OpenJPA out of the box, Eclipselink requires a tiny adapter.
Pax JPA supports load-time enhancement of entity classes, dynamically importing any required additional packages by weaving hooks, to avoid tying a persistence bundle to a given persistence provider.
The first public release Pax JPA 0.1.0 is now available from Maven Central.
