If I have:

-----------------------
ClientCallbacks.java
-----------------------
public interface ClientCallbacks extends java.rmi.Remote
{
    public void receiveMessage(String msg) throws java.rmi.RemoteException;
}

----------------------
ChatImpl.java
---------------------
    public void connect(ClientCallbacks cl) throws java.rmi.RemoteException
     {
           
     }

---------------------
Client.java
---------------------

ClientCallbacks callbacks;  
Connect.addActionListener(new ActionListener()
{
      public void actionPerformed(ActionEvent e)
        {
           // Complete to add action for connect.
       }
 }
);


As you can see, the connect.addActionListener wants to call the method Connect() in ChatImpl.java. How can I code that?? Would this work?

         Chat cs = new ChatImpl();
         cs.connect(callbacks);

??

this works if

//Chat.java

interface Chat{
  public void connect(ClientCallbacks cl) throws java.rmi.RemoteException;
}

ChatImpl implements Chat{

    public void connect(ClientCallbacks cl) throws java.rmi.RemoteException
     {
          //do something
     }

}
