While we stopped using this a while back in favor of Jserv, Sun's java web server
had a managment applet that would tell you if a servelt was loaded, and let you
unload it. The applet was a major pain, but the feature was very nice. I'd like to
find a way to do it with jserv, but I think it would require some interface to the
processes inside the jvm. Maybe that could be part of the jserv servlet itself?
Just a thought.
