Hi,
I have a class hierarchi. ie A extends B
Now I have two tables A_TABLE and B_TABLE . A_TABLE is mapped to A and B_TABLE IS mapped to B using joined-subclass tag

i.e my a.hbm.xml look like





Now the issue is , when I save B ie when I call session.save (b's object) a new record is getting inserted for A also .i.e new record is inserting into A_TABLE.
How can I restrict A getting saved when I save B ?
Is there anything missing in what I did ? Or is it completey wrong to use "table per concrete class " aproach here ?

Thanks in advance.

For that you have to change
