I have no problems using discriminator Values if use single table approach.
But is it possible to force hibernate to use discriminator values for InheritanceType.JOINED?
Is it possible to do it use annotation? Thanks a million!

Did you already try with @org.hibernate.annotations.ForceDiscriminator ?

Yes, I did. I put ForceDiscriminator flag at the root entity right after @DiscriminatorColumn.

My goals here are :
1. easy creation of entity classes, hibernate can recognize the discriminator values and use them instead of setting the values in the code. (using joined inheritance)
2. more importantly, I want to use joined inheritance but I also need to achieve better performance. By that I mean, when querying the root entity, I do NOT want my JPA provider to do a ton of left joins, I want to do it in a lazy fetching way. Is that possible ?
Any advice would be greatly appreciated!
