EclipseLink in OSGI Error No Persistence provider for EntityManager named

I have an RCP 3.7 application (Equinox OSGI) using Gemini JPA (v1.2.0) and EclipseLink (v2.5.2). I can't get the right combination of Require-Bundle in Manifest.MF to read the persistence.xml. Does anyone have the a working MANIFEST.MF they can share?

All the other questions I found referred to older versions of EclipseLink and an Eclipselink.jar that is not in the distribution. I read the documentation at Gemini JPA but did not find it specified.

Based on other posts I have also

  • Added org.eclipse.gemini.jpa to autoStart=true at startLevel = 3
  • Added my bundle with persistence.xml to autoStart=true at default
  • Added VM argument -DREFRESH_BUNDLES=false

Thanks for taking the time to read my question!

Solution

  • Their were several issues that needed to be resolved.

    1. No DB provider - Add Gemini DBAccess to project
    2. Wrong PersistenceProviderResolver loaded - the static inner class was being loaded instead of OSGiProviderResolver. Solved by #4 below.
    3. Cycles in DS and JPA resulting in multiple Exceptions - Added VM argument -DREFRESH_BUNDLES=false
    4. Bundles needed to be configured to autoStart="true" startLevel="3"
