This is a big deal and it needs to be addressed by Hibernate. Do some searching and you're led to believe using Hibernate as a persistence provider in Glassfish is as easy a changing a couple lines in persistence.xml. Not so fast. Hibernate does not properly implement the spec as related to inheritance and use of @DiscriminatorColumn I just ran into this problem. This is a big deal and it needs to be addressed by Hibernate.

It's very important to me to have not null value of discriminator field, I use it in group queries. Now I have to do something like in base classes: public MyBase () { // set the value of discriminator's field name = this.getClass().getSimpleName(); } I think it is really ugly :( Another option is to start to use Toplink...
