问题
I want to consume SAP webservices in my android app. The webservices are working as intended in SOAPUI (generated requests from the sap wsdl). I have tried using ksoap2 . When using ksoap2 I get "Webservice processing error" as response. I have exhausted all results from google/stackoverflow/sap community network. I have tried the request sent from ksoap2 in SOAPUI, but I am unable to pin down the crucial difference between it and the working (SOAPUI generated) request. Please guide me.
ksoap2 code:
public class SoapRetail extends Activity {
private static final String NAMESPACE = "urn:sap-com:document:sap:rfc:functions";
private static final String SERVICE_URL = "http://icanhazcheezburger.com/sap/bc/srt/rfc/sap/zretail_exec_topproducts_webs/100/zretail_exec_topproducts_webs/zretail_exec_topproducts_webs";
private static final String METHOD_NAME = "ZRetail_Exec_TopProducts_WebS/ZRFC_TOPCUSTOMER_NEWRequest";
private static final String SOAP_ACTION = "urn:sap-com:document:sap:rfc:functions/ZRetail_Exec_TopProducts_WebS/ZRFC_TOPCUSTOMER_NEWRequest";
private static final String USERNAME = "Alex";
private static final String PASSWORD = "hunter2";
private static final int TIMEOUT = 10000;
@Override
protected void onStart() {
super.onStart();
TextView txt = (TextView) findViewById(R.id.textView1);
txt.setTextSize(10);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapObject so_etTopCustomers = new SoapObject(NAMESPACE,
"ET_TOPCUSTOMERS");
SoapObject so_item = new SoapObject(NAMESPACE, "item");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER10); //Also tried VER11 and VER12
envelope.dotNet = false;
envelope.setOutputSoapObject(request);
PropertyInfo kunnr = new PropertyInfo();
kunnr.setName("KUNNR");
// kunnr.setValue(""); // Tried with and without these
// kunnr.setType(String.class);
so_item.addProperty(kunnr);
PropertyInfo name1 = new PropertyInfo();
name1.setName("NAME1");
// name1.setValue("");
// name1.setType(String.class);
so_item.addProperty(name1);
PropertyInfo custnum = new PropertyInfo();
custnum.setName("CUSTNUM");
// custnum.setValue("");
// custnum.setType(String.class);
so_item.addProperty(custnum);
PropertyInfo netwr = new PropertyInfo();
netwr.setName("NETWR");
// netwr.setValue("");
// netwr.setType(String.class);
so_item.addProperty(netwr);
so_etTopCustomers.addSoapObject(so_item);
request.addSoapObject(so_etTopCustomers);
PropertyInfo i_toplist = new PropertyInfo();
i_toplist.setName("I_TOPCUST");
// i_toplist.setValue("10");
// i_toplist.setType(String.class);
request.addProperty(i_toplist);
HttpTransportSE androidHttpTransport = new HttpTransportSE(SERVICE_URL,
TIMEOUT);
androidHttpTransport.debug = true;
try {
List<HeaderProperty> headerList = new ArrayList<HeaderProperty>();
headerList.add(new HeaderProperty("Authorization", "Basic "
+ org.kobjects.base64.Base64.encode(USERNAME+":"+PASSWORD
.getBytes())));
headerList
.add(new HeaderProperty(
"SOAPAction",
SOAP_ACTION));
Log.i("Info", "Now trying androidHttpTransport.call()...");
androidHttpTransport.call(SOAP_ACTION, envelope, headerList);
SoapObject response = (SoapObject) envelope.getResponse();
} catch (IOException e) {
Log.e("IOException", "androidHttpTransport.call()");
e.printStackTrace();
} catch (XmlPullParserException e) {
Log.e("XmlPullParserException", "androidHttpTransport.call()");
e.printStackTrace();
}
txt.setText("Request sent:\n\n" + androidHttpTransport.requestDump
+ "\n\nResponse recieved:\n\n"
+ androidHttpTransport.responseDump);
Log.d("Request sent", androidHttpTransport.requestDump);
Log.d("Response recieved", androidHttpTransport.responseDump);
SoapObject result = null;
try {
Log.i("Info", "Now trying envelope.getResponse()...");
result = (SoapObject) envelope.getResponse();
} catch (SoapFault e) {
Log.e("SoapFault", "envelope.getResponse()");
e.printStackTrace();
} catch (Exception e) {
Log.e("Exception", "envelope.getResponse()");
e.printStackTrace();

}

UPDATE:
I am able consume webservices, using a different approach, i.e. without using ksoap2. I copied the SOAP UI generated response and sent it in a HTTP POST request. I had to add SOAPAction and Auth headers. If anyone needs the code let me know. Thanks all. I leave the question open since I am not able to do so using ksoap2.
