Yup there's no standard CMP engine provider API.
MVCSoft uses a neat way to do it:
You program your bean as CMP, create ejb-jar.xml for it and then pass it
to MVCSoft's tool, it derives a new class from your CMP bean as "BMP",
and creates a new ejb-jar.xml where your cmp bean is not used as
ejb-class but the derived BMP one, and it handles persistence there. So
there's no need for a cmp provider API to plug into the app server.
PS: I have no relation with MVCSoft.
