Hi all,
This only applies to people still considering buying a working ejb 1.1
server and want to use toplink. Inprise currently has a beta integration of
TopLink with their EJB 1.1 server. Probably does not help most of the people
here but if anybody is a experienced TopLink user please checkout the
integration and help create a even better product.
http://www.inprise.com/appserver/ the beta integration can be obtained
through the newsgroup this product has at
news://forums.inprise.com/inprise.public.appserver
kind regards
William Louth
