Hi Björn, Pax JPA is not released, that's why it's not documented ;-) But there's not much to it - have a look at Pax JPA's own integration tests.
The idea is to implement an OSGi-compliant JPA service - no more, no less, without any dependencies on Spring or Blueprint, enabling automatic byte code weaving/enhancement, without being tied to any particular JPA implementation. At the moment, Pax JPA registers an EntityManagerFactory for each persistence bundle, and enhancement works automatically using an OSGi 4.3 Weaving Hook. Tested successfully for OpenJPA and Eclipselink. What's still missing is an EntityManagerFactoryBuilder (not available in Gemini or Aries either). Pax JPA does not (and never will) help you managing EntityManagers or transactions, as this is not part of the OSGi JPA spec. Of course, declarative transactions is what I'm ultimately aiming for, but these shall be achieved in combination with Pax CDI and DeltaSpike JPA, see [1] for a first example.
