> Is there a way to implement such a logging in earlier versions of OpenJPA?
Yes. Core OpenJPA kernel has all the necessary functionality for audit operations. if you are *not* interested in the 'delta' between the current and pre-change state of an entiity, the task becomes simpler. As you have noted a standard LifCycle Event State change callback mechnism should suffice. > I cannot get a reference to entity manager in event listener. You can albeit with some work. The persistence entity when enhanced, implements a PersistenceCapable interface. Hence, it is safe to cast the persistence entity to a PersistenceCapable. The PersistenceCapable.pcGetGenericContext() method returns you an object which is a Persistence Conext -- which is same (for all practical purpose) as an EntityManager. The Persistence Context in OpenJPA is called Broker. So it is safe to cast the result of PersistenceCapable.pcGetGenericContext() to Broker. Broker has all the methods you will find on an EntityManager. Actually EntityManager is implemented as a very thin delegation layer on Broker. You could always get a deeper and better explanation on the source (remember OpenJPA is Open Source :) and JavaDoc.
