Ok, that makes sense. I don't use beans, by those definitions, just TOs (structs) and BOs. TOs go out of the application (to the UI and such), and can only be created by BOs. BOs are used within the application (for business logic, passing to DAOs, etc). I don't know that it's the best way, but it does seem to be a good way, and works well for me.
