> The Persistence Unit service acts as the client doorway to JPA. It is registered under
> org.osgi.jpa.PersistenceUnit service interface name. Clients that want to access and
> operate on entities in a particular named persistence unit look up the service and use
it to obtain a
> JPA entity manager factory, from which an entity manager and other JPA artifacts can
> subsequently obtained.
> The service is implemented as a ServiceFactory so that when a client looks up the service
> provider can identify the dependencies of the calling client. The provider must then
create an entity
> manager factory for the persistence unit version corresponding to the calling client's
