Exception in parsing JSON in android

My code is :

     SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,
        OPERATION_NAME);
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
        SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);

    HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);

    try

    {

        httpTransport.call(SOAP_ACTION, envelope);
        Object response = envelope.getResponse();
        System.out.println("response : " + response.toString());
}

The response shown in the console :

03-21 14:23:30.532: INFO/System.out(4311): response : Map{item=anyType{key=2; value=Apple; }; item=anyType{key=1; value=Orange; }; }

How can i parse this JSOn Object.. I have tried with

JSONObject jObject = new JSONObject( response.toString()); 

But an exception is thrown :

03-21 14:17:03.423: WARN/System.err(4210): org.json.JSONException: Value Map of type java.lang.String cannot be converted to JSONObject

My web service method :

 public JSONObject getContactNames(){
        JSONObject names = load();
        System.out.println("names "+names);
        return names;

    }
