Exception when trying to run example of SOAP with Yaws

I'm trying to run this example of SOAP with Yaws.

I believe that I installed erlsom correctly.

This is what I get:

    1> inets:start().
    ok
    2> yaws_soap_lib:call(
    2>       "http://www.webservicex.net/WeatherForecast.asmx?WSDL",
    2>       "GetWeatherByPlaceName",
    2>       ["Boston"]).
    {ok,undefined,
        [{'soap:Fault',[],
                       {qname,"http://schemas.xmlsoap.org/soap/envelope/","Server",
                              "soap","soap"},
                       "System.Web.Services.Protocols.SoapException: Server was unable to process request. --->

Solution

  • I tried this service in SoapUI and got the same result. If you look at the response, it says:

    301 Moved Permanently

    Which means the service endpoint is not at the location specified in the WSDL at the URL you've used. It indicates the web service is now here:

    http://graphical.weather.gov/xml/SOAP_server/ndfdXMLserver.php

    But it is not the same web service. I tried one method and it appears whoever made it didn't quite understand SOAP. The method returned an escaped XML document as a payload.

    So, bottom line, it looks like your attempt is correct (or at least partially correct), they just moved the service somewhere else.
