[jboss-user] [EJB 3.0] - @PersistenceContext annotation in an abstract superclass

[bruce@dpi]

Hello All,

I know that the JBoss EJB3 implementation allows me to use the @PersistenceContext annotation in an abstract superclass.

For example:

public abstract class MyAbstractSuperclass implements MyInterface {

	@PersistenceContext()
	EntityManager entityManager;

	// Other code which I have omitted 

}

Can anyone point me to EJB3 documentation which specifies that using the @PersistenceContext in an abstract superclass is valid according to the specification and will therefore be portable across application servers? 

Many thanks,
Bruce.
