http://www.jcreator.com/forums/index.php?showtopic=7100&pid=21894&mode=threaded&start=#entry21894thread on the topic that talks about that and I still have no idea why I get this "command" class problem, but I did make a class called command and then I got this error (its with jinpur.jar included)

EDIT:: I got the netbeans example to work so I'm happy for now, but thanks for at least trying.
