HTTP tunnel request rejected: No tunnel created

[Michał Kalinowski <mi...@uni.opole.pl.INVALID>]

Hello,

I am trying to setup Guacamole connection in my Spring Application. I am 
almost done, but I keep getting the following error:

*/HTTP tunnel request rejected: No tunnel created/*

This is what I see in browser console:

/POST http://localhost:8080/tunnel?connect/

/Error: 404/

(seems like some connect attribute is empty? But how do I set it and 
what should be inside it?)
//

This is how I add the appropiate servlet to my app:

/@Bean//
//    public ServletRegistrationBean<GuacamoleConnector> 
exampleServletBean() {//
//        ServletRegistrationBean<GuacamoleConnector> bean = new 
ServletRegistrationBean<>(//
//          new GuacamoleConnector(), "/tunnel/*");//
//        bean.setLoadOnStartup(1);//
//        return bean;//
//    }/

This is how I create a tunnel: (almost exact as in Guacamole guide)

/protected GuacamoleTunnel doConnect(HttpServletRequest request, String 
IP) throws GuacamoleException {/

/ GuacamoleConfiguration config = new GuacamoleConfiguration();//
//            config.setProtocol("vnc");//
//            config.setParameter("hostname", IP);//
//            config.setParameter("port", "5900");//
//            config.setParameter("password", "password");//
////
////
//            GuacamoleSocket socket = new ConfiguredGuacamoleSocket(//
//                    new InetGuacamoleSocket("example.mydomain.com", 
4822),//
//                    config//
//            );/

/}////
////
//            return new SimpleGuacamoleTunnel(socket);/


Javascript on my page is *exact* as in Guacamole guide. Did not change a 
thing.

My docker log:

/guacd[7]: INFO: Creating new client for protocol "vnc"//
//guacd[7]: INFO: Connection ID is "$d0e0811a-1985-4ca8-b37f-c7ca6d67bdad"//

present)//
//guacd[618]: ERROR:      User is not responding./

/guacd[626]: INFO:       User "@0b559c19-46b5-48a3-a503-b6cd5c169bd5"

"$06545683-6b86-46f1-893d-e88ea7aea6e8" disconnected
guacd[626]: INFO:       Internal VNC client disconnected/

/
/

And finally the code that invokes the connection:

/@GetMapping(value = "/displayer")//
//    public String goVNC(@RequestParam String IP, HttpServletRequest 
request, Model model)//
//    {//
//        GuacamoleConnector guacConnect = new GuacamoleConnector();//
//        try {//
//            GuacamoleTunnel tunnel = guacConnect.doConnect(request,IP);//
//            return "displayer";//
//        } catch (GuacamoleException e) {//
////
//            e.printStackTrace();//
//            return "error";//
//        }//
////
//    }/

(I don't think the HttpServletRequest argument is needed, because 
/doConnect()/ method doesn't do anything with it. Servlet is handled by 
the bean I showed above)

I would appreciate some clue on the case, as I think I am so close to 
making it work!

P.S. Thank you for help with my previous problem *@Nick Couchman*! 
Worked like a charm.
