Yes, it looks in all contexts - so if you put it in any of them it
should work. The one from reading menu-config.xml gets put in
application, allowing you to customize at the different levels/scopes.

Note that you'll have to do this every time you want to view the page
since the repository will disappear once the page is done loading.�
You could also put it into the user's session and then it would stay
there for duration of their session - however long you have that set
to.

Matt,
I found a different, maybe less elegant solution to that:
In the Struts-Action I put the stuf f in the application context:
�������
session.getServletContext().setAttribute(MenuRepository.MENU_REPOSITORY
_KEY, repository);
In the Jsp I take it from the application context:
��� <%
��� pageContext.setAttribute("repository",
(MenuRepository)application.getAttribute(MenuRepository.MENU_REPOSITORY
_KEY));
��� %>
At least this works fine but may not be efficient.
What I do not understand: (Just for a better understanding how it
works behind the scenes)
��� <menu:useMenuDisplayer name="CoolMenu4" repository="repository">
�� .........
��� </menu:useMenuDisplayer>���
Where does it look for the "repository" object? Does it lookup in all
contexts (Page, Request, Session, Application)?
Cheers
Tom

Subject: [struts-menu] Newbee - How to create a dynamic menu in a
Struts Action?
Hi,
I usually work with Velocity and not with JSP. However I decided to
build my menu with JSP and mix Velocity and JSP. The problem is, that
I have no experience with JSP.
To create a dynamic menu I looked at the database sample. I have the
following question:
How can I put my menu repository from a Struts Action into a JSP Page
Context ?????
I have a Struts Action that builds the menu as follows:
��� public ActionForward perform(ActionMapping mapping, ActionForm
form,
��� ��� ��� ��� ���������������� HttpServletRequest request,
HttpServletResponse response)
��� throws IOException, ServletException
��� {
������� ActionForward af = super.perform(mapping, form, request,
response);
������� if (af != null)
����������� return af;
������� ........
������� buildMenu(session);
������� .....
������� return (new ActionForward("/Templates/Test.jsp"));
��� }
���
��� protected void buildMenu(HttpSession session)
��� {
��� ��� MenuRepository repository = new MenuRepository();
��� ��� MenuRepository defaultRepository = (MenuRepository)
��� ���
session.getServletContext().getAttribute(MenuRepository.MENU_REPOSITORY
_KEY);
��� ��� repository.setDisplayers(defaultRepository.getDisplayers());
��� ���
������� MenuComponent mc = new MenuComponent();
������� mc.setName("Test Menu 1");
������� String title = "Menu Title";
������� mc.setTitle(title);
������� //mc.setLocation("location");
������� repository.addMenu(mc);
�������
��� �� // WHERE TO PUT THE REPOSITORY OBJECT (IN WHICH CONTEXT??)
������ // I should do something like
JSPPageContext.setAttribute("reporsitory", repository);
��� }
In the Test.jsp I would like do do something like:
��� <menu:useMenuDisplayer name="ListMenu" repository="repository">
��� ��� <menu:displayMenu name="Test_Menu_1"/>
��� </menu:useMenuDisplayer>���
Many thanks for your help!
Tom.
