public interface serverInt extends Remote {

T executeTask(task t) throws RemoteException;

}

Spoiler for interface clientMain:






import java.rmi.registry.*;



public class clientmain

{ static opserver op;

static serverInt comp;

public static void main(String[] args)

{ int act;

if (System.getSecurityManager() == null) {

System.setSecurityManager(new SecurityManager()); }

try {

String name = "stoks";

Registry registry = LocateRegistry.getRegistry(args[0]);

comp = (serverInt) registry.lookup(name);

op=new opserver();

//tampilkan GUI

GUI d=new GUI();

d.setVisible(true); }

catch (Exception e)

{ System.err.println("Client exception:");

e.printStackTrace();}

}

}











if (System.getSecurityManager() == null) {

System.setSecurityManager(new SecurityManager()); }

try {

String name = "stoks";

Registry registry = LocateRegistry.getRegistry(args[0]);

comp = (serverInt) registry.lookup(name);

op=new opserver();

yang di atas itu buat apa ya gan..??

Spoiler for servermain:






import java.rmi.*;

{ public static void main(String[] args)

{ //set securitymanager

if (System.getSecurityManager() == null) {

System.setSecurityManager(new SecurityManager());

}

try {

String name = "stoks";

serverInt engine = new server();

serverInt stub = (serverInt) UnicastRemoteObject.exportObject(engine,0);

Registry registry = LocateRegistry.getRegistry();

registry.rebind(name, stub);

System.out.println("ComputeEngine bound");}

catch (Exception e)

{ System.err.println("ComputeEngine exception:");

System.out.println(e);

e.printStackTrace(); }

}

}











serverInt engine = new server();

serverInt stub = (serverInt) UnicastRemoteObject.exportObject(engine,0);

Registry registry = LocateRegistry.getRegistry();

registry.rebind(name, stub);

command d atas buat apa ya gan..??
