Hmmm, this isn't too Jini 2.1 friendly ^^^^^ .jar wise but it probably
doesn't matter for now.

Hmmm, are your classes in a .jar or are they in a directory?

If they're in a directory, try adding an additional "/" to that codebase
thus:

    System.setProperty("java.rmi.server.codebase", "http://" +
 InetAddress.getLocalHost().getHostAddress() + ":" + port + "/");
