Audit logging - how to acces SSO in Hibernate

[info]

I'm using Hibernate Listeners PreUpdateEventListener and  
PreInsertEventListener to do audit logging in the DB.

Now my problem is, how can I get access in the EventListenr class to  
the SSO where the user is stored? As Hibernate loads
the classes as defined in the config file (see below), I can not bind  
them using AppModule and @Inject something - or at least I do not know  
how.

I searched the list but found no solution (or did not understand it ;-)

Thx, Max
