Re: jsp:includes or c:imports of action AND new tag for in struts config

[David Evans <ds...@berndtgroup.net>]

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.

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.
