I use Hibernate as persistence framework, but just declaring a class as an Entity Listener and a method to do pre persistence does not work. Hibernate's annotation documentation doesn't say anything about how to apply lifecycle events in this case. I'm lacking the knowledge how to that.
Meanwhile, Franco Ferndandes submitted to me answers on his post, basically saying that "experts recommended that I do not rely on this method only because it is not portable between diff JPA providers. So you would actually do this create a stub method prepersist () in base and call it in save() and then for every descendant just override your prepersist()."
