Class OsgiSessionFactoryService

java.lang.Object

org.hibernate.osgi.OsgiSessionFactoryService

All Implemented Interfaces:

org.osgi.framework.ServiceFactory

public class OsgiSessionFactoryService
extends Object
implements org.osgi.framework.ServiceFactory

Hibernate 4.2 and 4.3 still heavily rely on TCCL for ClassLoading. Although our ClassLoaderService removed some of the reliance, access to the proper ClassLoader via TCCL is still required in a few cases where we call out to external libs. An OSGi bundle manually creating a SessionFactory would require numerous ClassLoader tricks (or may be impossible altogether).

In order to fully control the TCCL issues and shield users from the knowledge, we're requiring that bundles use this OSGi ServiceFactory. It configures and provides a SessionFactory as an OSGi service.

Note that an OSGi ServiceFactory differs from a Service. The ServiceFactory allows individual instances of Services to be created and provided to multiple client Bundles.
