Hello everybody,

I am trying to study how to use polymorphism and self-referencing.
To make things clearer let's say we have a Context generic class (abstract) with several concrete implementations that reference a Context father.

I would like to map these relations in Hibernate and my idea is to use polymorphism.

My guess is that
I think I can handle that either with joined-subclass or subclass tags but not with the union-subclass one.

Am I right ? Or is there a way to do also with union-subclass? In fact I can't see how it would be possible with the SQL tables behind that last mapping.

Thanks in advance for your help!

Regards

Pascal
