You might want to take a look at Tiles. It lets you solve exactly this
kind of page composition problem. It can do a lot more than just include
trailing content, too.

I solved this problem, by using the source of the struts IncludeAction.
I hijacked that code and did my List generation before the the
RequestDispatcher formward call, so it looks like:
Action snippet: ******************
List menuItems = getMenuItemsList();
req.setAttribute("menuitems", menuItems);
RequestDispatcher rd =
servlet.getServletContext().getRequestDispatcher("/WEB-INF/jsp/frontend/footer_include.jsp");
// Forward control to the specified resource
rd.include(req, res);
// Tell the controller servlet that the response has been created
return (null);
**********************************
So I'm wondering, has anyone ever heard of a proposal to allow for an
<include> tag inside an <action> tag in the struts config, to complement
the <forward> tag? so instead of the above i could just config like
this:
<action
path="/sidenav"
type="com.whatever.actions.SideNavAction">
<include name="showForm" path="/WEB-INF/jsp/sideNav_form.jsp" />
</action>
It would seem like useful functionality and a more clear and struts like
solution to the above problem.

Hello all,
I have a requirement for a dynamically created menu on all pages of a
web site i am creating. So i created an action that creates a List of
MenuItems, and then forwards to a jsp that uses jstl to forEach through
the list and generate the appropriate html. the jsp page only has the
snippet of html for the menu div of the page. I am including this action
in "static" html pages via the use of apaches SSI module like this:
<!--#include virtual="/apps/footer" -->
and thought i was going to use jsp:include to include it in all of the
jsp pages to which my applications actions are forwarding, like this:
<jsp:include page="/apps/footer" />
However when i attempt to do that i get a:
java.lang.IllegalStateException: Cannot forward after response has been
committed
This does work:
<c:import url="http://www.domainname.com/apps/footer"; />
but i'd prefer not to have to use that, because then i'll have to change
it when things move from dev to production, so far my jsp's have no site
specific information, so i can just copy them.
So can someone tell me how/if i can include the results of an action in
a jsp that is being forwarded to from another action?
Thanks
Dave
