The extent-class tag specifies the persistent subclasses of a class. So if you have class A, class B as a subclass of A, and class C as a subclass of B, then you would write:
<class-descriptor class="A"> <extent-class class-ref="B"/> </class-descriptor> <class-descriptor class="B"> <extent-class class-ref="C"/> </class-descriptor> <class-descriptor class="C"> </class-descriptor> Note that this other way around from how you specify it in Java (class C extends B, class B extends A).
