I have attempted your suggestion:
In C's class descriptor:
<reference-descriptor name="super" class-ref="A"
auto-update="true">
<foreignkey field-ref="mId" />
</reference-descriptor>
In A's class descriptor:
<extent-class class-ref="C" />
However, I still receive the error message:
Caused by: org.apache.ojb.broker.metadata.MetadataException: Class A is
not a superclass of class C
Preventing ojb from loading repository.xml and starting up
Could I be missing something else?

You specified A in the reference descriptor, not B, so I guess you want
to bypass B in this mapping. For this to work, B should not be declared
in the repository.xml and you need an extent-class in the class
descriptor of A that points to C.
If you did not want to bypass B, then the super-reference should point
to B, not to A.
