this means my EL expressions should evaluate, right?
Don't worry about that stuff, focus on your app. The first thing to do
is to make sure you're using a Servlet 2.4 web.xml. It should look
something like this:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";
version="2.4">
...
</web-app>
If you're using a Servlet 2.3 web.xml, then EL will be ignored by default.
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}
thanks again....
