I have a copy of Win2003 Server Edition here, so I just now installed it in VMWare (under Linux), then installed whatever the current default Java thing is from the the link on www.jempeg.org, and finally the current jemplode.jar from www.jempeg.org.

Communicates just fine with my v2.01 player. The "rebuild database from memory" (or whatever it's called) option didn't work for me, but no issues with Jemplode retrieving/browsing data.

EDIT: ah.. I'll try a regular sync now..

Cheers
