[Hibernate-issues] could not create proxy factory for: Employee

[JS P. S. <su...@js...>]

Hi,

Hi,

I'm not quite sure if this is the right mailing list, but hope it is as I'm
not sure how to solve my problem. The hibernate forum viewed many times but
did not reply. So here goes:

I have the folowing mapping (simplified for post):


<class name="PhisicalEntity" table="PHISICAL_ENTITIES">
   <id name="id" type="java.lang.Long" column="id" />

   <joined-subclass name="Employee" table="EMPLOYEES">
       <key column="phisicalentityId" />
   </joined-subclass>

   <joined-subclass name="Company" table="COMPANIES">
       <key column="phisicalentityId" />
   </joined-subclass>
</class>


Where PhisicalEntity is the super class for Employee and Company. Now when I
fetch my Set of employees for a company I get the exception shown below. How
does Hibernate handle the ProxyFactory for a joined-subclass and how can I
prevent this exception?

Thank you,
Joost

The exception:
