Facing a problem in creating session factory for object that is having the two references of same class. e.g.
class Person {
Address correspondenceAddress;
Address personalAddress;
}

While creating session factory for the above maping file we are facing the above exception.

Please help me out.

Is there something missing from that mapping? I can't see a column "AddressId" once, nevermind twice. Did you edit the mapping while posting it?

Anyway, try being explicit about what class the many-to-ones relate to (class="Address" or whatever). If that doesn't help, post the mapping for Address.

OOPs Sorry Its my Fault!!!

yes u r right, Actually i was writing AddressId for both the columns as column which was creating problem but when i putted original column names from the table problem resolved.
Anyways thanx for the reminding my mistake.
