Problem with displayer

Hello People.

 

I'm having a problem with ListMenu Displayer (and any displayer) I'm trying
to use struts menu dynamic maybe you can find the error, because I can't!

My files are like this:

 

This is part of my actionServlet....

 

MenuRepository repo = buildMenu(session, menu);

 

            session.setAttribute("user", user);

            session.setAttribute("perfil", perfil);

            session.setAttribute("unread", denuncia);

            

//I have put repo is session

session.setAttribute("repositorio", repo);

            return mapping.findForward("success");

 

      } // end execute

 

      private MenuRepository buildMenu(HttpSession session, Vector menu) {

            

            MenuRepository repository = new MenuRepository();

            

            // Get the repository from the application scope - and copy the

            // DisplayerMappings from it.

            MenuRepository defaultRepository =

                  (MenuRepository) session.getServletContext().getAttribute(

                        MenuRepository.MENU_REPOSITORY_KEY);

            

            repository.setDisplayers(defaultRepository.getDisplayers());

 

            

            for (int i = 0; i < menu.size(); i++) {

                  

                  MenuComponent mc = new MenuComponent();

                  MenuBean row = (MenuBean)menu.elementAt(i);

                  String name = row.getNombre();

                  mc.setName(name);

                  String parent = row.getParent();

                  System.out.println(name + ", parent is: " + parent);

 

                  if (parent != null) {

                        MenuComponent parentMenu =
repository.getMenu(parent);

                        if (parentMenu == null) {

                             System.out.println(

                                   "parentMenu '" + parent + "' doesn't
exist!");

                             // create a temporary parentMenu

                             parentMenu = new MenuComponent();

                             parentMenu.setName(parent);

                             repository.addMenu(parentMenu);

                        }

 

                        mc.setParent(parentMenu);

                  }

 

                  String title = row.getTitulo();

                  mc.setTitle(title);

                  String location = row.getLocation();

                  mc.setLocation(location);

                  repository.addMenu(mc);

            }

            

            return repository;

      }

In my jsp file I have this (tld is ok!) because I have used TabbedMenu in
static way.

 

<menu:useMenuDisplayer name="ListMenu" repository="repositorio">

            <menu:displayMenu name="Menu1"/>

            <menu:displayMenu name="Menu2"/>

         </menu:useMenuDisplayer>   

 

This is menu-config.xml

 

<?xml version="1.0" encoding="UTF-8" ?>

 

 

<MenuConfig>

 

  <Displayers>
