Struts does not (and indeed *can* not in a Servlet 2.2 / JSP 1.1
environment) override the request object. I suspect you might be getting
confused between request *parameters* (things that came in on the original
request) and request *attributes* (things an Action might have put there).
>From within a tag implementation, you can get to request parameters like
this:
String foo = pageContext.getRequest().getParameter("foo");
While request attributes can be retrieved like this:
String foo = pageContext.getAttribute("foo", PageContext.REQUEST_SCOPE);
Because you mentioned "request scope", I'm betting that the latter is what
you really want to use.
