Classcastexception

[ssuyamboo]

Hi,
I am using the simple insert/retrieval against postgres using hibernate 3.1rc1 and jboss 4.0.3SP1.

My hbm.xml is below,<hibernate-mapping>





















</hibernate-mapping>

I am able to successfully store data , but during retrieval it throws java.lang.ClassCastException.

OrderDTO orderdto = null;
try{
orderdto=(OrderDTO) retrieveObj(OrderDTO.class, id);
} catch (ClassCastException e){
e.printStackTrace();
}

When I checked the following,
retObject instanceof OrderDTO) this line returns false
retObject.getClass().getName() returns com.xpe.ecommerce.order.model.OrderDTO

Can anyone give a hint? Is this because of reflection failure?

Thanks
Sun
