But i am not using duplicate entries for UpperMenu.hbm.xml. i tryied to change the order of hbm.xml file in hibernate.cfg.xml but still i am getting this error for the first hbm.xml file i add.
e.g
<mapping resource="com/buyspace/hibernate/User.hbm.xml" />
<mapping resource="com/buyspace/hibernate/RetailerMaster.hbm.xml" />
<mapping resource="com/buyspace/hibernate/UserType.hbm.xml" />
<mapping resource="com/buyspace/hibernate/UpperMenu.hbm.xml" />

in this case i get same error for User.hbm.xml
