Source: https://github.com/wicketstuff/core/wiki/projects/Push

Example demonstrating the general usage pattern of wicket-push, including setting up an IPushEventHandler, obtaining an IPushService, installing a push node, and forwarding events from a background service.

/*
 * panel constructor
 */
public ChatPanel()
{
    // setup UI components ...

    /*
     * 1. instantiate push event handler
     */
    IPushEventHandler handler = new AbstractPushEventHandler<Message>()
    {
        public void onEvent(AjaxRequestTarget target, Message message, IPushNode<Message> node, IPushEventContext<Message> ctx)
	{
                // TODO your component update logic goes here...
	}
    });

    /*
     * 2. obtain a reference to a Push service implementation
     */
    IPushService pushService = TimerPushService.get();

    /*
     * 3. install push node into this panel
     */
    IPushNode<Message> pushNode = pushService.installNode(this, handler);

    /*
     * 4. connect to the chat service and forward the Message events to the push node and it's event handler
     */
    IChatService chatService = ServiceLocator.getChatService();
    chatService.addListener(new IChatListener() {
        public void onMessage(Message msg)
        {
            if (pushService.isConnected(pushNode))
                // forward the Message event via the push service to the push event handler
                pushService.publish(pushNode, msg);

			@Override
			protected void setup(Attributes attributes, Bindings bindings)
			{
				// which objects are going to be accessable
				bindings.put("nashornObject", nashornObject); 
			}

			@Override
			protected Writer getWriter()
			{
				// Where to write output
				return new BufferedWriter(new OutputStreamWriter(System.out)); 
			}

			@Override
			protected Writer getErrorWriter()
			{
				// Where to write errors
				return new BufferedWriter(new OutputStreamWriter(System.out));
			}

			@Override
			protected boolean isDebug()
			{
				// Outputs AST information and other stuff while executing the actual script
				return true;
			}

			@Override
			protected ClassFilter getClassFilter()
			{
				// default is to allow nothing!
				return new ClassFilter()
				{
					@Override
					public boolean exposeToScripts(String name)
					{
						// which classes are allowed to be accessed (name is full qualified)
