Rmi server communicating with client

Question

Is there any way for an rmi server to communicate back to the client? What I mean is, the client connects to the server and calls some method x(). One of the arguments of x() is the client(x(AClient ac)). Assume that AClient is a JFrame and has a method y() which adds a button to the frame or something. If the server calls ac.y(), in my understanding/experience, the server would actually create a local copy of AClient and add the button to the local copy, not to the frame that the client user is looking at.Is this correct? { 
  If so, is there any way to have ac.y() add the button to the client user's frame?
    If not, does anyone have any ideas for how to implement something like this relatively easily? 
If not, does anyone have any ideas why it's not responding that way for me?I'm trying to avoid programming socket connections for this, and would love to be able to do it with rmi.
Thanks in advance,

Not sure exactly what your starting point is. But:
1. The client must be a UnicastRemoteObject.
2. If your client is behind a firewall, then the scheme probably won't work. (Explored exhaustively in this forum.)
