Setting up Hibernate Discriminators

As I understand it, if I have constraints set up in my database, Hibernate will pretty much reverse-engineer everything I need (POJOs). Really Nice.

However, if I have polymorphic relationships (subclasses, etc.), then does the reverse engineering for POJO subclasses still work as long as I set up the database to have the "discriminator" columns?

What I'm asking is if I have a case where I need to use discriminators for polymorphic relationships, do I then need to manually edit/create the HBM mapping files or will Hibernate still reverse engineer everything for me (POJOs for subclasses, for example) as long as I set up the database to have the correct strategy (table per subclass, for example)?

Thanks in advance.

I agree. Here's the link:
