WebService no connection from javascript

I try to get the WebService example running:

Querying the vi via browser does work.

using the submit button leads to connection error:

I am not sure if this is related, but there is not WebService displayed in WIF configuration.

The mentioned example hardcodes port 8001 into the request. (addTwoWithSubmit.js)

 

function update()
{
URL = "http://127.0.0.1:8001/WebClient/AddTwo?first="
URL = URL + $('#firstNumber').val() + "&second=" + $('#secondNumber').val();

 

I replaced this code with:

 

URL = document.URL;
URL = URL.replace("addTwoWithSubmit.html", "") + "AddTwo";
URL = URL + "?first=" + $('#firstNumber').val() + "&second=" + $('#secondNumber').val();

 

now it works.
