I save object with the following code:

public boolean saveAndUpdate(TblCustomerInfo customerInfo) {

Session session=getHibernateTemplate().getSessionFactory().openSession();
try{
Transaction tx=session.beginTransaction();
session.saveOrUpdate(customerInfo);
tx.commit();

if(tx!=null){
try{
tx.rollback();
}
catch(HibernateException ex){
ex.printStackTrace();
}
}
}
catch(HibernateException ex){
ex.printStackTrace();
}

return true;
}


But it give the error:

org.hibernate.TransactionException: Transaction not successfully started
at org.hibernate.transaction.JDBCTransaction.rollback(JDBCTransaction.java:149)
at com.callcenter.dao.impl.CustomerManagerDAOImpl.saveAndUpdate(CustomerManagerDAOImpl.java:73)
at com.callcenter.service.impl.CustomerManagerImpl.saveAndUpdate(CustomerManagerImpl.java:38)

at com.callcenter.web.pages.EditCustomer.dispatchComponentEvent(EditCustomer.java)
at org.apache.tapestry.internal.structure.ComponentPageElementImpl.dispatchEvent(ComponentPageElementImpl.java:843)
............



and i query the table,the data is saved with this error,how to remove this error???

try{
tx.rollback();
}

put this code in exception block.. you need to rollback only when the exception accurs and not on succefull commit..
