Run RMI client error message

Question

I have a correction of an exercice we have done in class so its supposed to be working fine. But Im not able to execute it properly.

When I run the Remote object its all fine I have the message on the screen showing me its working but when I run the client afterwards I guedd this error :

**java.rmi.ConnectException: Connection refused to host: Sony-PC; nested exception is:

Im desperate, I tried everything. Maybe someone could tell me step by step how to get this to work.Thank you for your help !

Here s the Remote interface :

    import java.rmi.Remote;
    import java.rmi.RemoteException;

    public interface IRemote extends Remote {

    void echo() throws RemoteException;

    void echo(int value) throws RemoteException;

    String getRemoteAddress() throws RemoteException;

}

Remote Object CLASS :

import java.net.InetAddress;
import java.net.MalformedURLException;
import java.net.UnknownHostException;
import java.rmi.AlreadyBoundException;
import java.rmi.RMISecurityManager;
import java.rmi.RemoteException;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
import java.rmi.server.UnicastRemoteObject;

public class RemoteObject extends UnicastRemoteObject implements IRemote {

private static final long serialVersionUID = 1L;

protected RemoteObject() throws RemoteException {
    super();
}

@Override
public void echo() throws RemoteException {
    try {
        Thread.sleep(5000);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    System.out.println("RemoteObject.echo()");
}

@Override
public void echo(int value) throws RemoteException {
    System.out.println("RemoteObject.echo() value=" + value);
}

@Override
public String getRemoteAddress() throws RemoteException {
    try {
        return InetAddress.getLocalHost().getHostAddress();
    } catch (UnknownHostException e) {
        return "Unknown";
    }
}

public static void main(String[] args) throws RemoteException,
        MalformedURLException, AlreadyBoundException {
    if (System.getSecurityManager() == null) {
        System.setSecurityManager(new RMISecurityManager());
    }

    int rmiRegistryPort = 1099;

    // the rmiregistry can either be created programmatically or started
    // manually before each run if you have some time to waste
    Registry registry = LocateRegistry.createRegistry(rmiRegistryPort);
    System.out.println("RMI registry listening on port " + rmiRegistryPort);

    RemoteObject remoteObject = new RemoteObject();
    registry.bind("myremoteobject", remoteObject);
}

}

            System.out.println("Client.main() before echo remote call");
            distante.echo();
            System.out.println("Client.main() after echo remote call");

            distante.echo(7);
            System.out.println("Remote object IP: "
                    + distante.getRemoteAddress());
