Charlie Mordant commented on ARIES-1247:
----------------------------------------
Let's have a bundle with as content:
* An Hello entity
* A persistence.xml (referencing this HelloEntity)
* An HelloDao:
@OsgiService
public class HelloDao {
@Inject
@OsgiServiceReference
private EntityManagerFactory emf;
public void save (Hello hello) {
emf.createEntityManager().save(hello);//to sum up
}
}
Will this bundle could be in active state if the emf will be created once in
active state?
The dao EMF OSGI service reference will not be resolved so I think it won't
start...

Charlie

> EntityManagerFactoryManager:
> As it was already mentioned in ARIES-1160, I do not see any benefit for
> trying to create EntityManagerFactories on Bundle.RESOLVED event.
> On time of Bundle.RESOLVED the bundle context is still not initialized and
> trying of creation EntityManagerFactory will likely failed (Hibernate and
> EclipseLink implementations are failed by lookup of DataSource service).
> It only confuses user with a stack trace.
> The EntityManagerFactories will be created a tick later on Bundle.ACTIVE
> event by calling registerEntityManagerFactories() method.
> Patch is attached.
