I am trying to hit a web service with an android application. I am getting following exception about which I don't have any Idea. Please help:

The request is not even hitting the server. It gets fail at calling only. Following is my code for web service call:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv=(TextView)findViewById(R.id.hello);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
DataStore t=new DataStore("samsung");
PropertyInfo pi = new PropertyInfo();
pi.setName("name");
pi.setValue(t);
pi.setType(t.getClass());
request.addProperty(pi);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.setOutputSoapObject(request);
envelope.setAddAdornments(false);
envelope.implicitTypes=true;
envelope.addMapping(NAMESPACE, "DataStore",new DataStore().getClass());
AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
try{
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject response=(SoapObject) envelope.getResponse();
String Name = response.getProperty(0).toString();
tv.setText("Response :" + Name);
} catch (Exception e) {
e.printStackTrace();
}
}
An following is my java bean:
public class DataStore implements KvmSerializable
{
private static final String NAMESPACE = "http://service.hello.com";
private String path;
public String getPath() {
return path;
}
private void setPath(String path) {
this.path = path;
}
public DataStore(String path) {
this.path = path;
}
public DataStore() {
// TODO Auto-generated constructor stub
}
public Object getProperty(int arg0) {
Log.d("KVM","gp");
switch(arg0)
{
case 0:
Log.d("KVM","after");
return path;
}
return null;
}
public int getPropertyCount() {
Log.d("KVM","gpc");
return 1;
}
public void getPropertyInfo(int index, Hashtable arg1, PropertyInfo info) {
Log.d("KVM","gpi "+index);
switch(index)
{
case 0:
info.type = PropertyInfo.STRING_CLASS;
info.name = "path";
break;
default:break;
}
}
public void setProperty(int index, Object value) {
Log.d("KVM","sp");
switch(index)
{
case 0:
path = (String)value;
break;
default:
break;
}
}
public void register(SoapSerializationEnvelope cm) {
// TODO Auto-generated method stub
Log.d("KVM","register");
cm.addMapping(NAMESPACE, "DataStore", this.getClass());
}
}
Please help me in resolving this issue.

回答1:
If you have soapfault you need to parse the answer by hand :( on your exception
catch (Exception e) {
e.printStackTrace();
}
and I think you using old version of ksoap2 :( http://code.google.com/p/ksoap2-android/
this gives you the answer then you can use sax parser or other to parse your answer:
androidHttpTransport.responseDump;
if you find other way to do these please tell me I would be appreciated.

Check your property names in android are the same with web service side .
For example .
PropertyInfo pi = new PropertyInfo();
pi.setName("name");
pi.setValue(t);
pi.setType(t.getClass());
your paramater name "name" may not same in web service method. Check Out !

I use the following method:
/**
* Method to retrieve the errorMessage from the given SoapFault.
* @param soapFault
* @return String representing the errorMessage found in the given SoapFault.
*/
private static String getSoapErrorMessage (SoapFault soapFault) {
String errorMessage;
try {
Node detailNode = soapFault.detail;
Element faultDetailElement = (Element)detailNode.getElement(0).getChild(1);
Element errorMessageElement = (Element)faultDetailElement.getChild(0);
errorMessage = errorMessageElement.getText(0);
}
catch (Exception e) {
e.printStackTrace();
errorMessage = "Could not determine soap error.";
}
return errorMessage;
}
