Hi,

I have a scenario as follows.

Class A - No table (used to create id, and some common fields)

Class B - Union subclass of class A

Class C - Sub class of class B.

Class B can have many sub classes. How do i specify a discriminator?
This is what i tried.

1) Added the discriminator in Class A , but it didn't set the discriminator value in database. All other columns defined in Class A got persisted.
2) Tried adding discriminator in Class B , but hibernate didn't parse the xml.

Kindly help me resolve this.
