I may be wrong but from my reading, I seem to recall that JPA supports unregistered objects, so JPA may be able to help you here. I think JPA also supports non-persisted objects in the class hierarchy, so you might even be able to define a TemporaryMeeting subclass (or superclass) of Meeting that would never be persisted.
Thank you Mike! That would be very very good :-) Does any body has more information on that subject? Peter.
