Thanks, Tim and Alasdair, for your clarifications - I wasn't aware of the Aries
JNDI service before, and I didn't have an explicit
transaction-type="RESOURCE_LOCAL" in persistence.xml.
I had another try with the aries.jpa.api, aries.jpa.container and aries.util
bundles added to my application. My persistence unit gets discovered, and I can
see an EntityManagerFactory in the service registry. However, this factory is
not usable, because of the following errors:
36 test.openjpa TRACE [Start Level Event Dispatcher] openjpa.MetaData -

The problem appears to be the bundleresource://... URL returned by
PersistenceUnitInfoImpl.getPersistenceUnitRootUrl(), which OpenJPA thinks is a
file, not a directory. I'm not really intimate with pax-exam, but apparently it
installs all bundles as JARs, whereas I'm launching Equinox directly from the
Eclipse IDE, so my bundles are installed from class folders, not from JARs,
which might explain why the Aries integration tests work and my setup does
not...
Anyway, it seems this is an issue on the OpenJPA side and not in Aries, so I'm
going to cross-post this on the OpenJPA mailing list.
Best regards,
Harald
