I have an object called User which implements KvmSerializable. Would like to pass this object to the webservice.

PropertyInfo pi = new PropertyInfo();
        pi.setName("obj");
        pi.setValue(user);
        pi.setType(user.getClass());
        request.addProperty(pi);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 

       envelope.setOutputSoapObject(request);
       envelope.addMapping(NAMESPACE, "User",User.class);
       HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

I get the following error....

Thanks.
