XMLPullParserException when trying to call wcf web service


I'm having problems connecting to my web service. I've followed a couple of tutorials, especially http://drclawx.wordpress.com/2011/06/24/77/ and created a simple Wcf Hello World web service. I've downloaded the ksoap2 jar recommended on the site, but I had a couple of problems. I've downloaded a couple of later versions but the one that I can get to work is version 2.5.8. When I go to call my own web service I'm getting an XMLPullParserException. My web service will be used to check login credentials, it has a method called 'UploadLogin' which takes a username and password. The following is my code

private class webService extends AsyncTask<String, Void, Void> {

    final String METHOD_NAME = "UploadLogin";
    final String NAMESPACE = "http://tempuri.org/";     
    final String URL = "http://10.0.2.2:52762/UploadService.svc";
    final String SOAP_ACTION = "http://tempuri.org/IUploadService/UploadLogin";

    // For the web service method: public String getLocations(String inputLocation))
    @Override
    protected Void doInBackground(String... entry) {

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty("username", "a");
        request.addProperty("password", "a");
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

        try {
            androidHttpTransport.call(SOAP_ACTION, envelope);

            Object response = (Object) envelope.getResponse();
            System.out.println("Login - " + response.toString());
        } 
        catch (Exception exception) {
            exception.printStackTrace();   
        }

        return null;
    } 
}

The error that I'm getting is the following. Can someone please help or suggest how I might go about fixing this issue.

Solution

  • For anyone that's interested, the reason I was getting this error was because the messageEncoding was using MTOM, so I changed this to Text and it work - messageEncoding="Text"
