An I reading this right? You have an optional request parameter called
"locale" that you can use to set the locale to something specific. If
that parameter is not found, then you check the session for Struts's
locale. (Note that the session has just been invalidated, so this is
likely to return null in this). If struts doesn't have one, then you use
the locale of the request (presumably from the client's provided headers).

It looks like that ought to do it. Are you sure you aren't ending up
with a NULL locale object in this code?

That suggests that Globals.LOCALE_KEY isn't set properly. Can you dump
out the contents of the session in various places? For instance, what
does the session contain both before and after this call:
chain.doFilter(req, res);
I haven't used the JSTL before... I assume Config.set(ses, foo, bar)
basically does ses.setAttribute(foo, bar), eh?
