That code is for the server part. You also have a class DisplayPerfectTime, which is the client part, which you didn't show us.

Are you running the client in an applet, or another environment which has restrictions? Applets run in a secure environment and can't do things like communicate over the network to any arbitrary server, or read and write files from and to the local filesystem.
