The sources are these:

import java.rmi.RemoteException;
publicinterface Helloextends Remote{
publicvoid sayHello()throws RemoteException;
}
package rmi;
import java.rmi.RemoteException;
publicclass HelloServerimplements Hello{
public HelloServer(){
super();
}
publicvoid sayHello()throws RemoteException{
System.out.println("Ciau!");
}
}
package rmi;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
import java.rmi.server.UnicastRemoteObject;
publicclass HelloMain{
publicstaticvoid main(String[] args){
try{
Hello obj =new HelloServer();
Hello stub = (Hello) UnicastRemoteObject.exportObject(obj, 0);
// Bind the remote object's stub in the registry
Registry registry = LocateRegistry.getRegistry();
registry.bind("Hello", stub);
System.err.println("Server ready");
}catch (Exception e){
System.err.println("Server exception: " + e.toString());
e.printStackTrace();
}
}
}
May be I'm wrong with start command, but I tried differents syntax without result.
Can you help me?
Thanks to all.
PS:Sorry for my spaghetti-english :D
