In this case what you could do is extend the ServerSocket, this may not
be the most elegant solution but it is quite easy. Try somthing like


public class MonitoredServerSocket extends ServerSocket {

   private Monitor monitor;

   public MonitoredServerSocket(Monitor monitor, int port) {
      super(port);
      this.monitor = monitor;   
   }

   public Socket accept() throws IOException {
      try {
         return super.accept();
      } catch(IOException e){
	 monitor.notifyException(this, e);
         throw e;
      }
   }
}

public interface Monitor {
  
   public void notifyException(ServerSocket sock, IOException e);
}

At least this way you can still use the ConnectionFactory without having
to recode your own connection framework.

Hope this is of use,
