Hi, check out Oracle Business Components for Java (BC4J) at their
Technet site. It seems Oracle people have strong ideas about
NOT using entity beans at all, be them BMP or CMP.
BC4J implements View Objects and Entity Objects to address these
kinds of problems. I very much agree with this approach.
