A problem with threads

Question

I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
Thank you in advance,
Lefty

This was one solution from the socket programming forum, have you tried this??
public Thread MyThread extends Thread{
     boolean active = true;          
     public void run(){
          ss.setSoTimeout(90);               
          while (active){                   
               try{                       
                    serverSocket = ss.accept();
               catch (SocketTimeoutException ste){
               // do nothing                   
     // interrupt thread           
     public void deactivate(){               
          active = false;
          // you gotta sleep for a time longer than the               
          // accept() timeout to make sure that timeout is finished.               
          try{
               sleep(91);               
          }catch (InterruptedException ie){            
          interrupt();
}
