Tip: Stopping listener in response to a Message

Question

I wanted to control a standalone server using JMS messages. For instance, tell it to suspend processing or shut down.
But you can't call Connection.stop() from within a MessageListener - it throws an IllegalStateException. So I found a little trick that got me over - do it from a different Thread.
public class ServerMessageListener implements MessageListener
    static ServerToolkit toolkit = new ServerToolkit();
    public void onMessage( final Message inMsg )
        try  {
            ServerCommand cmd = ServerFactory.makeCommand( inMsg );
            if( cmd != null )  {
                if( cmd.getType() == SUSPEND_CMD :  {
// TODO browse broker to purge any other Suspend messages 
                    toolkit.console("  ML received Suspend message.  Stopping connection.");
                    new Thread() {
                        @Override
                        public void run() {
                            try {
//                                      sleep(50);
                                toolkit.getConnection().stop();
                            catch( Exception ex ) {}
                    }.start();
      catch( Exception ex ) { ex.printStackTrace(); }
      finally  {
          try {  inMsg.acknowledge();  }
          catch( JMSException ex ) {  ex.printStackTrace();  }
}Now I have to figure out a way to get it to resume...

Hi,
I don't think you'll be able to achieve this natively in Lync. The only thing that comes to mind is to define a custom presence state that you could have Tier 1 Help Desk change to in the event of this happening. This would only be a proactive measure though,
and not reactive in providing an auto response.
Looks like you'd either need to jump in and create something leveraging the Lync API's yourself, or see if there's an auto-responder / bot plugin out there already that can do this for you.
I'm not familiar with any myself, but top of a quick google-fu moment pulled up

I must stress I've never used this, but its this type of app that might offer you the functionality you're after. I'm sure others here might be able to recommend something that's proven.
Kind regards
Ben
