illegal property webservice [closed]

I'm having a problem consuming my webservice.

I have the following method (This method will return all the users registered in the webservice that are in the database) User owns (id, name):

public ArrayList<Usuario> buscarTodosUsuario(){ 

    ArrayList<Usuario> lista = new ArrayList<Usuario>();

    SoapObject buscarUsuario = new SoapObject(NAMESPACE, BUSCARTODOS);

    SoapSerializationEnvelope envelope= new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.setOutputSoapObject(buscarUsuario);
    envelope.implicitTypes = true;

    HttpTransportSE http = new HttpTransportSE(URL);

    try {
        http.call("urn= "  + BUSCARTODOS, envelope);

        Vector<SoapObject> resposta = (Vector<SoapObject>) envelope.getResponse();

        for (SoapObject soapObject : resposta) {
            Usuario user = new Usuario();
            user.setIdUsuario(Integer.parseInt(soapObject.getProperty("id").toString()));
            user.setNome(soapObject.getProperty("nome").toString());
            lista.add(user);                
        }
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
    return lista;
}

The method call is:

ArrayList<Usuario> lista = dao.buscarTodosUsuario();
Log.d("ExemploWS", lista + "");

The error is:

TheUserclassis:

    }
