I have an abstract class and two concrete class which extend these abstract class. I have mapped all the three in a employee.hbm.xml file. It is throwing the following error. My db is mysql

Exception in thread "main" org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [temp.ContractEmployee#0]

.
