just search the archives of ejb-interest. this is an faq and you'll find
lots of suggestions. we use the RMI UID generation algorithm in our ejbs
which is OK if not using a cluster (in fact we don't really care about the
likelyhood of a rolled back transaction because of a conflict because it' s
negligible for us and we don't have a problem with that error if it means
every 10000th user might see an error screen, so what?).
