Methods Summary
protected java.util.MapgetDispatchTable()
all sub-implementation of this class can use a dispatch table to map xml element to method name on the descriptor class for setting the element value.

return
the map with the element name as a key, the setter method as a value

        Map table = super.getDispatchTable();

        // These are the EJB 2.0 elements that no longer exist in the EJB 2.1
        // schema.  We still set them on the descriptor but they will be
        // written out as activation config properties.
