I am a Noob.I have RTFM.
I am trying to do a simple table per class hierachy association.
My previous sample worked. However in this one, I have one class which has no body or properties but just extends a parent class. I am not even calling this code. However this gives a problem.
I have a base class User. and sub classes as X,Y,Z.
Z does not have any body. I am calling setters on class Y. and during running... the above given is the problem. I would be grateful if some one could point out the wrong in the code ( or the approach ?)

thanks

Thanks everyone, I solved it.
I dunno how, but this time, I copy pasted the variables from my User class into my hbm.xml, and it worked. guess a silly space some where.

Cheers..
