I'm somewhat confused by your question(s), but I'll give it a shot.

> Where and how should we declare the mapped super class?
You need to declare your common parent class via : [@(protected)
annotation in the parent class, or via the <mapped-super-class> element a
mapping (orm.xml) file.]

> We tried defining it in its own ORM mappings file but it doesn't seem to
be getting read as parent entity.
If you had all of your mapping information in one file (META-INF/orm.xml)
it should work, but It sounds like you have multiple mapping files. Did you
add a reference from your persistence.xml file to each mapping file via the
<mapping-file/> element? If not, that is most likely what is giving your
problems.

  <persistence-unit name="cache-mode-disable">
    <mapping-file>META-INF/caching-orm.xml</mapping-file> <!-- You need
one of these entries for each mapping file -->
    <shared-cache-mode>DISABLE_SELECTIVE</shared-cache-mode>
    <properties>

Hopefully this helps. Let us know how it goes.

Thanks,
Rick
