Yes. Specifically, you need a web server that will deliver a class file "without comment" so that the client-side RMI program will retrieve it. Sun has made available for some time a tiny web server that does just that -- serve classes, and no more. If you read through Sun's RMI tutorial, they also link to that tool. There's a link to it somewhere in the "RMI Start to Finish" topic that is part of this forum, but you'd have to dig a little to find that.
