Hi,
I am upgrading the test environment of the EMF Texo project to use the latest EclipseLink project. For this test
environment I generate persistence.xml file for each separate test model (there are around 50). So each testmodel will
have a persistence.xml called for example: accounting-persistence.xml
Until now I initialized Eclipselink like this:
properties.put(PersistenceUnitProperties.ECLIPSELINK_PERSISTENCE_XML, "META-INF/" //$NON-NLS-1$
+ getPersistenceXMLPrefix() + "-persistence.xml"); //$NON-NLS-1$
so that it made use of the correct persistence.xml when testing.
This doesn't work, it fails for example here:
Session session = SessionManager.getManager().getSession(getPersistenceUnitName());
as it can't find the accounting persistence unit, it seems that the accounting-persistence.xml is not being read.
Is there a way that I can accomplish this? Should I generate a sessions.xml file for each test model and more
importantly if so how can I tell EclipseLink to use that specific acccounting-sessions.xml (and a different one for each
testmodel)? And also which persistence.xml it will use.
Thanks for any insights in this!

Thanks, I am running in an OSGI environment, is there a way that I can use Gemini JPA without sessions.xml?
