Hi all, Thank you all for ur advices on my RMI/IIOP support question... There is another area i need help... Assumption: we would have CMP beans I am reading about SAPdb, and since it claims to have transaction support and row level locking, (which some other open source databses seem to be lacking) i am inclined to show some interest in SAPdb. Now, has anyone here used SAPdb in any project environments? Is there any particular aspect(s) that i need to be wary of? PS: I am not considering oracle primarily because it's license fee... Any sort of comment on SAPdb or a viable alternative is highly appreciated. Thanks again, Jobin Thomas
