Hi,
This is the hibernate tools generated DAO code:

I am trying to delete a record by this function:
Code:
public void deletePrStaffCost(PrStaffCostId prStaffCostId) throws Exception {
prStaffCostInstance = EjbUtil.lookup(PrStaffCostHome.class, "surgeonfish/PrStaffCostHome/local");
PrStaffCost prStaffCost = prStaffCostInstance.findById(prStaffCostId);
if(Util.isNull(prStaffCost)) {
throw new Exception("The record have been changed by any other user.");
}
prStaffCostInstance.remove(prStaffCost);
}
I am getting the error.
Am I missing some thing? Or do I have to change tool generated code?
