Runtime Error When getResponse using Android KSOAP

My Android get a runtime error in SoapObject result = (SoapObject) envelope.getResponse(); The webservice is in my notebook (192.168.15.13), the notebook and the Android connected via LAN. I created the web service using Axis2 in Knopflerfish OSGi. Here is my code:

package test.msani.aksessoap;

import java.io.IOException;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.SoapFault;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import org.xmlpull.v1.XmlPullParserException;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;

public class TesAksesSOAP extends Activity {
    private static final String SOAP_ACTION = "SOAPObjectSani.SOAPObjectSani/SOAPObjectSani/getKeterangan";
    private static final String METHOD_NAME = "getKeterangan";
    private static final String NAMESPACE = "SOAPObjectSani.SOAPObjectSani/SOAPObjectSani";
    private static final String URL = "http://192.168.15.13:8080/axis2/services/SOAPObjectSani";
    TextView tv;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceSt开发者_JAVA技巧ate);

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

        //set parameter
        PropertyInfo pi = new PropertyInfo();
        pi.setName("angka");
        pi.setValue(2);
        pi.setType(int.class);
        request.addProperty(pi);

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

        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        Log.i("Sani", "coming 1");

        try {
            Log.i("Sani", "coming 2");
            androidHttpTransport.call(SOAP_ACTION, envelope);
            Log.i("Sani", "coming 3");
        } catch (IOException e) {
            tv.setText("IOException");
        } catch (XmlPullParserException e) {
            tv.setText("XmlPullParserException");
        }

        SoapObject result = null;
        try {
            Log.i("Sani", "coming 4");
            result = (SoapObject)envelope.getResponse(); //I get the error here
            Log.i("Sani", "coming 5");
        } catch (SoapFault e) {
            tv.setText("SoapFault");
        }

        //to get the data
        String resultData = result.getProperty(0).toString();

        tv.setText("" + resultData);

        setContentView(tv);
    }
}

and here is the WSDL

help me please...

Use this line

 response = (SoapObject) envelope.bodyIn;

Instead of

result = (SoapObject)envelope.getResponse();
