Hi there
I'd like to use EclipseLink in an OSGi server environment (Equinox),
but I can't get an EntityManagerFactory. I've done some successful
tests with a milestone some weeks/months ago, but this doesn't work
anymore.
When I try to get the EntityManagerFactory in the Activator's start
method of the bundle that contains the persistence.xml
(javax.persistence and org.eclipse.persistence.jpa are started one
osgi start level before), I get the following errors:
1) When I don't specify any properties:
Persistence.createEntityManagerFactory("unitname");
The OSGiPersistenceInitializationHelper#getClassLoader is called
with "bundleresource://7/unitname" and doesn't find an entry for this,
because the map contains only a key "unitname".
2) When I specify Thread.currentThread().getContextClassLoader() as a
class loader property, this class loader doesn't find the resource
"META-INF/persistence.xml" in
PersistenceProvider#createEntityManagerFactory:95.
What am I doing wrong?
BTW: it would be very helpful when the EclipseLink website would
provide an OSGi SDK zip download which contains the source plugins. I
had to checkout the projects from the SVN tag to debug the problem...
Thanks for any hint,
Beat Strasser

Well ok. With a class loader property
"this.getClass().getClassLoader()" it works.
