Timeout a client app

Question

I have a java GUI client/server application that uses swing classes and AWT . I need to timeout the client application after 4 hours. Does anyone have any tips of how to do this?
Do I try to timeout the RMI socket connection or do I try to use some sort of listener to see if there has not been any activity for 4 hours on the client? I'm not sure how to start.

Answer 1

Why not:
Every time there is activity on the RMI set a timer to occur after 4 hours, if you delete the old timer and create a new one every time the RMI has activity then you only have one timer and it will occur if, and only if, nothing has happened on the RMI for 4 hours. Youm can then deal with the RMI connection, etc as you want.
So :
    java.util.Timer myTimer = new Timer();
    // The timeout is in milliseconds.
    myTimer.schedule(new MyHandler(), 0, 4*60*60*1000);Above starts a timer that will occur after 4 hours.
Use:
      myTimer.cancel();
     myTimer.schedule(new MyHandler(), 0, 4*60*60*1000);To cancel the old timer and start a new one.
MyHandler needs to extend java.util.TimerTask and do whatever you want. When you extend TimerTask you then implement the run() method:
  public void run()
    // Do your work here
  }run() is called if the timer ever occurs.
