Yup, another semi-empty template without field declarations. Anyone
interested in implementing it?
Anyway, maybe we can simply not generate any derived class at all? The
optimistic locking feature will be lost, but some container support it
(though many others don't). Maybe making it configurable is the right
solution?
Also I think the generated blablSession class for session beans is not
needed, but if you want to use the custom-session.j capability you can
put a generate-subclass="true" in your bean.

Great! Implement it and share it with us. Highly appreciated.
Three things we don't have for full EJB 2 support:
- relations
- EJBQL query
- don't generate cmp subclass with declared fields
Ara.
