Hibernate, JDBC driver and OSGi problem

I ran into a somewhat depressing problem. I use Apache Felix as my OSGi platform, and Im also uses Hibernate for persistence issues.

Im using the "osgi-bundle" version of Hibernate (com.springsource.org.hibernate-3.2.6.ga.jar). As far as I know, this is Hibernate Core with some additional osgi-metdata installed in META-INF / MANIFEST.mf. This information (Package-Export and Package-Import) is vital for osgi systems.

My problem is that Hibernate cannot find my JDBC drivers. It is very difficult to add Import statements to the Hibernate springsource package. There must be a better way to solve this problem.

I ran into a similar problem a while ago. The solution was to register the jdbc-provider and jdbc-user bundles packages as buddies. This is because one package cannot use classes (therefore jdbc drivers too) from another without explicitly declaring it. This was for Eclipse, so I guess it might help you.

Hibernation is not a good OSGi citizen, since many of the assumptions that Hibernate makes for class visibility are no longer true in the OSGi container.
