Hi Team,
First of all thanks for making hibernate works in OSGi.
I've OSGi-fied some hibernate bundle a while ago, the main problem I encountered is the split package issue(same packages used by different bundles). For example, both hibernate-core and hibernate-annotations share some package, also hibernate-core and hibernate-entitymanager share some package. To resolve this problem in OSGi container, I create hibernate-annotations and hibernate-entitymanager as fragment bundle, attach those to hibernate-core(hibernate-core play the role as host bundle), so all resource in fragment bundle is available for host bundle.
I know it's just a workaround, the ideal clean solution should refactor Hibernate to remove any split package between modules, also resolve any potential classloading issue in OSGi.
Anyway, I will append the projects I created, it basically use maven-bundle-plugin and maven-shade-plugin to add OSGi metadata headers to each jar. Those projects works for my scenario in Karaf/Fuse ESB with Aries JPA.
Best Regards
Freeman
