mapping CMP EJBs to existing tables

Did I miss something or is there really no way to map container managed EJBs to existing tables?

As you seemingly only can map fields of an entity bean to tables done in a dictionary project I can't think of a way to do it unless there is a way to trick dictionary projects to resemble existing tables instead of tables managed by the dictionary.

This really prevents porting many existing apps to NW04 the 'easy way'.
