Losing Locale after Sesion.invalidate()

[Chris Pratt]

I am having a strange problem with JSTL locale's after Session.invalidate.
I am using JSTL as the main TagLib with Struts 1.2.9.  So to keep both
systems in sync, I have a servlet filter that executes this code:

 protected void doFilter (HttpServletRequest req,HttpServletResponse
res,FilterChain chain) throws IOException, ServletException {
   Locale locale;
   HttpSession ses = req.getSession();
   String locstr = req.getParameter("locale");
   if(locstr == null) {
     if((locale = (Locale)ses.getAttribute(Globals.LOCALE_KEY)) == null) {
       locale = req.getLocale();
     }
   } else {
     locale = new Locale(locstr);
   }
   if(locale != null) {
     ses.setAttribute(Globals.LOCALE_KEY,locale);
     Config.set(ses,Config.FMT_LOCALE,locale);
   }
   chain.doFilter(req,res);
 } //doFilter

This works great except when, after the LogoutAction calls
Session.invalidate(), I redirect to a "Logout Success" page.  For some
reason that page picks up the French text from the application_fr.properties
resource file for the JSTL tags, but not for the Struts tags.

I have put lots of debugging in the stream and from what I can see, the
Locale is getting set in the filter, but by the time the JSP page is
processed, Config.FMT_LOCALE is null.

Any insights would be greatly appreciated.
