Hi ranchers,
I am new to Hibernate. I just tried a simple one to many association using an item class and a bid class. I somehow inserted a row into the item table using hibernate and later saw that the bid table was not updated with the record. So i deleted the record in the Item table from MySQL command prompt and tried to once again insert into Items table but i am getting the following error.

ERROR AbstractBatcher:51 - Exception executing batch:

This is just a guess, but you don't seem to be closing your session. So, what may have happened was that Hibernate still had the Item associated with the session. Then when you deleted it directly from the DB, Hibernate got confused.

Also, I notice you don't have inverse="true" set for your bi-directional relationship. I'm guessing you got an error before this one when you tried to persist the Item? That error would have occurred because Hibernate would have tried to write the ITEM_ID foreign key twice, once for the many-to-one and once for the one-to-many.
