KSoap HTTP 500 Error

Question

I am working on android project and I am trying to implement KSoap library.

I have created a C# Console application that is hosting a C# WCF soap service and I am trying to get android to talk to the soap service.

Below is my C# WCF Service.

class SoapServer : ISoapInterface
    {
        public string testSoapFunction()
        {
            return "Hello World";
        }
    }

Below is the Soap Interface

[ServiceContract]
    public interface ISoapInterface
    {
        [OperationContract]
        string testSoapFunction();
    }

Below is how the soap service is started

try
            {
                if (Environment.GetEnvironmentVariable("MONO_STRICT_MS_COMPLIANT") != "yes")
                {
                    Environment.SetEnvironmentVariable("MONO_STRICT_MS_COMPLIANT", "yes");
                }
                if (String.IsNullOrEmpty(soapServerUrl))
                {
                    string message = "Not starting Soap Server: URL or Port number is not set in config file";
                    library.logging(methodInfo, message);
                    library.setAlarm(message, CommonTasks.AlarmStatus.Medium, methodInfo);
                    return;
                }
                baseAddress = new Uri(soapServerUrl);
                host = new ServiceHost(soapHandlerType, baseAddress);
                BasicHttpBinding basicHttpBinding = new BasicHttpBinding();

                var meta = new ServiceMetadataBehavior()
                {
                    HttpGetEnabled = true,
                    HttpGetUrl = new Uri("", UriKind.Relative),
                };

                host.Description.Behaviors.Add(meta);

                var debugBehaviour = new ServiceDebugBehavior()
                {
                    HttpHelpPageEnabled = true,
                    HttpHelpPageUrl = new Uri("", UriKind.Relative),
                    IncludeExceptionDetailInFaults = true

                };

                ServiceEndpoint endpnt = host.AddServiceEndpoint(
                    soapManagerInterface,
                    basicHttpBinding,
                    "EmailServer",
                    new Uri("", UriKind.Relative));


                host.Description.Behaviors.Remove(typeof(ServiceDebugBehavior));
                host.Description.Behaviors.Add(debugBehaviour);
                host.Opened += new EventHandler(host_Opened);
                host.Faulted += new EventHandler(host_Faulted);
                host.Closed += new EventHandler(host_Closed);
                host.UnknownMessageReceived += new EventHandler<UnknownMessageReceivedEventArgs>(host_UnknownMessageReceived);
                host.Open();

Below is how I am calling the service via android.

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final String soapAction = "http://tempuri.org/ISoapInterface/testSoapFunction";
        final String namespace = "http://tempuri.org/";
        final String methodName = "testSoapFunction";
        final String url = "http://192.168.1.69:8000/CritiMon";
        String resultData = "";

        new Thread(new Runnable() {

            @Override
            public void run() {
                String resultData = "";
                SoapSerializationEnvelope soapEnv = new SoapSerializationEnvelope(SoapEnvelope.VER11);
                SoapObject request = new SoapObject(namespace, methodName);

                soapEnv.setOutputSoapObject(request);

                HttpTransportSE http = new HttpTransportSE(url);
                http.debug = true;

                try
                {
                    http.call(soapAction, soapEnv);

                    SoapObject result = (SoapObject)soapEnv.bodyOut;
                    if (result != null)
                    {
                        resultData = result.getProperty(0).toString();
                        Log.d("Soap Result", resultData);
                    }
                }
                catch (Exception ex)
                {
                    Log.e("Soap", ex.toString());
                }

            }
        }).start();

When I run the above code I am getting the following response:

java.io.IOException: HTTP request failed. HTTP Status: 500.

Within the soap server I also fire the unknown message received event handler which contains

<v:Envelope xmlns:i="http://www.w3.org/2001/
    XMLSchema-instance" xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:c="http://s

Answer 1

I found the issue finally.

It was an issue with the web service, I was assuming it was an issue with my implementation with Android. There was a type in the soap interface so the android call wasn't finding the function.

Thanks for the help.
