KSOAP and web server communication (PropertyInfo)

Question

So I'm developing an Android app that should connect to a web service. This connection is working fine. I've tested it using a simple method that returns "Hello Christian". This is displayed correct in the app. If I try to do this with a parameter (name) it returns "Hello null".

Technically I'm working with Android 4.2.2 and KSOAP 2.6.5. The web service is running on an Oracle WebLogic v12. Following my source code:

private final String NAMESPACE_Local = "http://test.com/";
private final String URL_Local = "http://168.185.226.69:7001/neuesProjekt/neuerWebServiceService";
private final String SOAP_ACTION_Local = "Hello_Action_Name";
    private final String METHOD_NAME_Local = "helloname";

    private final String URL_Local = "http://168.185.226.21:7001/myTest/myTestWebServiceService";
  private final String SOAP_ACTION_Local = "Hello_Action_Extend";
   private final String METHOD_NAME_Local = "hello_extend";

        public void LocalServer(View view)
        {
            TextView text = (TextView) findViewById(R.id.update_text);

            SoapObject request = new SoapObject(NAMESPACE_Local, METHOD_NAME_Local);
    //      request.addProperty("name", "Christian");

    //      String name = "Christian";
    //      
    //      PropertyInfo nameProp =new PropertyInfo();
    //        nameProp.name = "name";
    //        nameProp.type = String.class;
    //        nameProp.namespace = NAMESPACE_Local;
    //        nameProp.setValue(name);
    //        request.addProperty(nameProp);

            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.setOutputSoapObject(request);
            HttpTransportSE androidHttpTransport = new HttpTransportSE(URL_Local);

            try {
                androidHttpTransport.call(SOAP_ACTION_Local, envelope);
                SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
                Log.i("myApp", response.toString());


            text.setText(response.toString());

        } catch (Exception e) {
            Toast.makeText(this,"Device or service offline",Toast.LENGTH_LONG).show();
        }
    }

I've tried to add the propertyInfo in two ways. First with the simple request.addProperty and the long way creating the PropertyInfo and adding it afterwards. Both ways don't work. However when I try it with a server from some tutorial (eg. celsius to fahrenheit) it works and returns the proper answer.

Here the 'code' from the web server:

package com.test;

import javax.jws.*;

@WebService
public class myTestWebService {

    @WebMethod(action="Hello_Action")
    public String hello() {
        return "hello";
    }

    @WebMethod(action="Hello_Action_Extend")
    public String hello_extend(String name)
    {
        return "hello "+name;
    }
}

Following the WSDL file in case it helps solve my problem:

    </operation>
  </binding>
  <service name="myTestWebServiceService">
    <port name="myTestWebServicePort" binding="tns:myTestWebServicePortBinding">
      <soap:address location="REPLACE_WITH_ACTUAL_URL"/>
    </port>
  </service>
</definitions>

So I hope one of you can help me because I'm quite clueless what to do. Kind regards, Christian

I'm not great at this and in fact have only this week got my web services to work.

Try

envelope.dotNet = true;
String name = "Christian";
request.addProperty("name", name);

Or

envelope.dotNet = true;
PropertyInfo nameProp =new PropertyInfo();
nameProp.setName("name");
nameProp.setType(String.class);
nameProp.setValue(name);
request.addProperty(nameProp);

I hope this solves it for you
