java.lang.ClassCastException: org.ksoap2.serialization.SoapPrimitive?

Question

I am calling a web service from my android client application. After getting response when i am trying to display it i am getting ClassCastException. Following is my code:

public void onClick(View v) {
  setContentView(R.layout.report);
  SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
  EpcDetails epcdetails=new EpcDetails();
  epcdetails.setEpcId(input_val.getText().toString());

        request.addProperty("id", id
        SoapSerializationEnvelope sse=new SoapSerializationEnvelope(SoapEnvelope.VER11);
        sse.setOutputSoapObject(request);

        sse.addMapping(NAMESPACE, 
        ProductDetailsRequest.ProductDetailsRequest.getSimpleName(),
        ProductDetailsRequest.ProductDetailsRequest);

        sse.implicitTypes=true;
        sse.setAddAdornments(false);
        AndroidHttpTransport aht=new AndroidHttpTransport(URL);

        try 
        {
         aht.call(SOAP_ACTION, sse);
         SoapObject response= (SoapObject) sse.getResponse();
         item_code.setText((CharSequence)(response.getProperty(6)));
         desc.setText((CharSequence) (response.getProperty(5)));
         price.setText(calc_price.toString());

        } catch (IOException e) 
        {
         e.printStackTrace();
        } catch (XmlPullParserException e)
        {
          e.printStackTrace();
       }

I am getting Exception at item_code.setText((CharSequence)(response.getProperty(6))); as

Answer 1

because the type of your webservice return is String ，so you can solve it this way:

Object  response=  sse.getResponse();  

when your webservice return values type is byte[] ,you can do it

SoapObject response=(SoapObject)envelope.bodyIn;

Answer 2

May be your web service is returning an XML object which is causing ClassCastException at client's end as it is not supported by KSOAP, try returning result of your web service as a String(preferably with CDATA) and your problem would get solved.
