//Server implementation
public class InfoServerImpl 
	extends UnicastRemoteObject

//Constructor
public InfoServerImpl() 
	throws RemoteException {
	System.out.println("Creating Server Object");
}

//Remote method implementation
public String getInfo()
	throws RemoteException,ServerNotActiveException{
	String msg="CLIENT INFO\n";

	//Return the hostname of the current client.
	msg += getClientHost();
	return msg;
}

//main method
public static void main(String args[]) { 
   try { 

	//create a server object
	InfoServerImpl obj = new InfoServerImpl(); 
	 		
	//bind the remote object
	Naming.rebind("Server",obj);
	System.out.println("Server ready"); 
       } catch (Exception ex) { 
	   System.out.println("Error: " + ex.getMessage()); 
       } 
   } 
}

The getInfo() method of the server calls the getClientHost() method of the RemoteServer class. The getClientHost() method returns the hostname of the current client.
