如何使用kSOAP从Android向.NET发送/接收自定义对象？

Question

So, I am a newbie in mobile development and interoperability. I am developing a Android application that comunnicates send a Contact object to a remove server that is running a .NET Web Service (via kSOAP). But there is a 500 error in the server and I really don't know how to map it because it is running remotely and my host plan doesn't allow me to debug remotely. I believe it is an error in the interpretation of the Java object in the ASP.NET Web Service, I don't know if it is necessary to deserialize the object and how to do it. I hope that a more experienced developer could help me. I already used primitive objects (string, int and others) and it worked like a charm but I really prefer to work with my models.

The Android Application - Call of the Web Service:

     public int webServiceMethodRegisterUser(String... paramss)
{
    String resultData;
    try {
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        Contact c = new Contact(paramss[0], paramss[1]);
        c._email = paramss[0];
        c._password = paramss[1];
        c._cellphonesim = paramss[2];
        c._simoperator = paramss[3];
        PropertyInfo pi = new PropertyInfo();
        pi.setName("contact");
        pi.setValue(c);
        pi.setType(c.getClass());
        request.addProperty(pi);
        //request.addProperty("useremail", paramss[0]);
        //request.addProperty("userpass", paramss[1]);
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet=true;
        envelope.setOutputSoapObject(request);
        envelope.addMapping(NAMESPACE, "Contact" , new Contact().getClass());
        //Marshal floatMarshal = new Marshal();
        //floatMarshal.register(envelope);
        //Marshal oi = new ();

        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        androidHttpTransport.call(SOAP_ACTION, envelope);
        Object result=(Object)envelope.getResponse();
      //To get the data.
        resultData= result.toString();
        publishProgress(resultData);
        return Integer.parseInt(resultData);
    } catch (Exception e) {
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e1) {  
            throw new RuntimeException(e1.toString());

          }  
        throw new RuntimeException(e.toString());
    }
}

I've been stuck in this for a while and didn't found any implementation and deserialization of a java model in .NET. I hope someone out there helps me! =D

Answer 1

ThiagoMello, I had this error days ago and solve it generting java class from this site:

http://www.wsdl2code.com/Pages/Home.aspx

With this classes my code works fine! Try it.

Hope this helps.
