to "OO domain model" and "business methods" in some way ? Of course, yes!

The problem is what does "business...]]> Wed, 01 Sep 2004 16:14:45 -0400 Wed, 01 Sep 2004 16:14:45 -0400 Wed, 01 Sep 2004 16:14:45 -0400 Sep 1, 2004 ja vp 0 http://www.theserverside.com/discussions/thread.tss?thread_id=28371 Wed, 01 Sep 2004 16:09:54 -0400 Wed, 01 Sep 2004 16:09:54 -0400 Wed, 01 Sep 2004 16:09:54 -0400 Sep 1, 2004 Abhijit Deb 2 http://www.theserverside.com/discussions/thread.tss?thread_id=28371 You do not need to care about "business logic", this is job for business analyst.This is a kind of thinking that made sure J2EE did not enter into enterprise computing.

I would agree with J2EE impact statement too. I have seen quite a few project where multiple layers play "data ping-pong".
