[ANN] JDNC based project is beta
roomity.com to check it out.
it should help you use mail lists. It's RiA/JDNC. There should be updates weekly and it should release in days.
The only thing I did to JDNC is to recompile to allow 1.4 out of CVS. I do not use "datasources" in favor of mvc.
hope you like.
