Hello Thomas,

I have been having some problems using "super" to map an inheritance
hierarchy. Seems like ojb isn't treating the reference descriptor as a
special tag. I keep getting the following error:

"Can't find member super in com.cci.model.pharma.impl.AOMObjectImpl...."

The repository XML looks like this:

   <!-- Mapping for Class com.cci.model.pharma.impl.AOMElementImpl -->
   <class-descriptor
     class="com.cci.model.pharma.impl.AOMElementImpl"
     table="AOMElement"
   >
       <field-descriptor
         name="id"
         column="id"
         jdbc-type="VARCHAR"
         primarykey="true"
         access="readwrite"
       />
       <field-descriptor
         name="name"
         column="name"
         jdbc-type="VARCHAR"
         access="readwrite"
       />
   </class-descriptor>

   <!-- Mapping for Class com.cci.model.pharma.impl.AOMObjectImpl -->
   <class-descriptor
     class="com.cci.model.pharma.impl.AOMObjectImpl"
     table="AOMObject"
   >
       <field-descriptor
         name="id"
         column="id"
         jdbc-type="VARCHAR"
         primarykey="true"
         access="readwrite"
       />
       <reference-descriptor
         name="super"
         class-ref="com.cci.model.pharma.impl.AOMElementImpl"
         refresh="true"
       >
         <foreignkey field-ref="id"/>
       </reference-descriptor>
   </class-descriptor>

Please let me know if I am overlooking something.

Regards,
