How to consume web service using ksoap2

Question

I am trying to consume a web service for 2 days now and I failed. Here is my code :

String SOAP_ACTION = "urn:WsTestIntf-IWsTest#Test101";
                String METHOD_NAME = "Test101";
                String NAMESPACE = "urn:WsTestIntf-IWsTest";
                String URL = "http://wsig.127.cc:8465/WsTemp.dll/wsdl/IWsTest";

                String strTemp;

                SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

                SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
                envelope.setOutputSoapObject(request);
                HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
                try
                {
                    androidHttpTransport.call(SOAP_ACTION, envelope);
                    SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn;

                    strTemp = resultsRequestSOAP.toString();


                } catch (Exception e) {
                    strTemp = "Error : " + e.getMessage();
                }

                Toast.makeText(getBaseContext(), strTemp, Toast.LENGTH_SHORT).show();

What is wrong with it? I have place the INTERNET permission in my manifest. The web service is written in Delphi.

I had a rough time long back with ksoap2, but have a working client side code.. Hope it helps...

Note: It retries for 3 times, you can remove it if you want..

            } finally {
                if (xml == null)
                    xml = ""; // to avoid exception in while condition
            }
        } while (trycount < MAXTRY && xml.equalsIgnoreCase("Request Timeout"));

        return xml == "" ? "Something Went Wrong Please Try Again!" : xml;
    }
}
