looks there mapping pojo.blame. might had copy/paste mistake:
<class name="pojo.blame" in hbm file.
this
caused by: org.hibernate.duplicatemappingexception: duplicate class/entity mapping pojo.blame states when reached hbm file has definition class named pojo.blame.
looks in of files:
<mapping resource="pojo/blame.hbm.xml"/> <mapping resource="pojo/buyer.hbm.xml"/> <mapping resource="pojo/dispute.hbm.xml"/> <mapping resource="pojo/evidence.hbm.xml"/> <mapping resource="pojo/goods.hbm.xml"/> <mapping resource="pojo/message.hbm.xml"/> <mapping resource="pojo/record.hbm.xml"/> <mapping resource="pojo/seller.hbm.xml"/> <mapping resource="pojo/staff.hbm.xml"/> <mapping resource="pojo/trade.hbm.xml"/> <mapping resource="pojo/fund.hbm.xml"/> <mapping resource="pojo/showorderbybid.hbm.xml"/> is misplaced <class name="pojo.blame"
