Hi,<br>I already have an id as the primary key for the table say XYZ.<br><br>Now,
 I want to set a field or a combination of two fields as a unique key so
 that when i try to save say 2 entries in the DB with same value for the
 unique key field then only one entry should be made in the table with 
one primary key. I want hibernate to handle it internally and not throw 
me an exception.<br>
<br>Now i have only one auto-generated primary key and when i try to 
save 2 entries in the DB with same value for the unique key field it 
stores duplicate entries.<br><br>Is it possible? If yes how?<br><br>Thanks in advance<br>Ankita<br>
