Here is my code

import java.net.*;
public class PerfectTime extends UnicastRemoteObject implements PerfectTime1{
	//Imp of the interface:
	public long getPerfectTime() throws RemoteException{
		return System.currentTimeMillis();
	}
	//Must implement constructor to throw
	//RemoteException:
	public PerfectTime() throws RemoteException{
		//super() is called automatically
	}
	//Registration for RMI serving:
	public static void main(String[] args){
		System.setSecurityManager(new RMISecurityManager());
		try{
			PerfectTime pt = new PerfectTime();
			Naming.bind("NK/PerfectTime", pt);
			System.out.println("Ready to do time");
		}catch(Exception e){
			e.printStackTrace();
																		
		}
	}
}

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.
