thank you very much.. I put what you posted in my web.xml (in lieu of
what I had there previously (and what I have in all web.xml's in 
Tomcat), namely

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
      PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
     "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
    ....

I put the code you posted in both the web.xml for the particular webapp
and in conf/web.xml..  but EL expressions are still not evaluating..
this is how a JSP with EL prints in the browser (IE & FF..)

     Request Method: ${pageContext.request.method}
     Request Protocol: ${pageContext.request.protocol}
     Context Path: ${pageContext.request.contextPath}
           ....
     Remote Host: ${pageContext.request.remoteHost}
     Secure: ${pageContext.request.secure}
     Cookies: ${c.name}: ${c.value}
     Headers: ${h.key}: ${value}
