I've ported it twice now. Once to use jdbc and now it's using nsjava (see
http://nsjava.sourceforge.net) to provide the java support. I also just upgraded it with the changes from acs classic 3.3. I'm middle of testing now, so if Ben releases tonight as planned, I won't have it completely tested. In that case, you might have to wait a few days and grab the latest webmail version out of cvs.
