David,
I believe that you must write 30 class descriptors all exactly the same except for the class name :-( I have not been able to get this sort of scenario to work any other way.
It seems odd, since ojb "should" know the inheritance structure due to the extent-class tag. It would be nice if extent classes need only add field-descriptors for the attributes that are different.
the problem is that descriptors are not inherited by extent class.
At the least, it would be nice if I could specify one class-descriptor as being inherited from another. Even that seems way less than ideal.
