Hi,
This is the code that was executed to get access to my fitbit resources. In the Authentication method, i sent the scope.
public class Controlador extends HttpServlet {
/**
* Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.

* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
