Simple java architecture question

Question

This should be a simple question to answer but I haven't been able to find a good answer.
I have an application that establishes a network connection with a server and registers event listeners on that connection.
What I want to do is find a way without a busy-wait/while loop to keep the main() thread running so that the listeners can do their job.
Here is a sample of what I've got:
public static void main(String[] args)
SomeConnection conn1 = null;
try
conn1 = new SomeConnection("someaddress");
TrafficManager tm = conn1.getTraffictManager();
TrafficHandler th = tm.createTraffichandler(new MessageListener()
                    public void processMessage(Message message)
                         System.out.println("Received: " + message.toString());
     catch (Exception e)
          e.printStackTrace(System.out);
     conn1.disconnect();
The problem is that the application doesn't stay running to respond to traffic coming across the connection.
Any guidance would be appreciated.
Thanks

Well, what is the job of the MessageListener if it isn't to listen for messages? And apparently it isn't doing that because your application terminates.
Bear in mind that I don't have any idea how any of those four classes work, or even how they are supposed to work. So let me just quote this line from the API documentation of the Thread class which says when your application will terminate:
"All threads that are not daemon threads have died, either by returning from the call to the run method or by throwing an exception that propagates beyond the run method."
That must be the case in your application.
