question
I'm following the recommendations laid out by Shawn
Bayern in "JSTL In Action", but I've run into a snag.
On page 136, Shawn recommends using the <c:url> tag
for referring to a directory named images in a Web
application:
<body background="<c:url value='/images/gray.jpg'/>">
<!-- other HTML stuff in here
</body>
When I ask Tomcat to send this page, the background is
not there. When I View Source to look at the HTML, I
see this:
<body
background="/mock-trading-partner/images/gray.jpg;jsessionid=9B0DA55495E2CD9BF40AAD98A4E115D8">
Looks to me like that jsessionid is making it so I
can't find the background. How do I get rid of it?
Thanks - MOD

Is your browser configured to accept cookies? If not, URL rewriting will be used
for session management. As for actually having a session, by default any JSP
page will create one. If you don't want it to, you need to use the page directive:
<%@ page session="false" %>
Also, by using <c:url> with a relative URL, you're implicitly requesting URL
rewriting. The fact that the <c:out> version still rewrites the URL doesn't make
any sense, it doesn't do that. Try shutting down Tomcat, removing everything in
$CATALINA_HOME/work/Standalone/localhost, and then restarting.

Hi Kris,
I forced a refresh of the page and still didn't get
the background image to come down.
The <c:out> suggestion didn't do it, either. I still
see the jsession ID in the URL.
I'm missing something important here. I'll have to
keep digging. Thanks - MOD

Hi Kris,
I don't know - I didn't try hitting the page again.
I'll give it a try and see.
I was surprised to see it, because I don't have any
session scope variables in the page. I don't think I
should have a session open.
I'm using Tomcat 4.1.24 as the server.
I'll try your <c:out> suggestion and see if that

The next time you hit the page it works though, right? If you're tracking
sessions via cookies, subsequent responses won't need to do URL rewriting. It
actually looks like it's a server bug. Hitting
http://www.sun.com/im/sun_logo.gif;jsessionid=foo
works just fine (SunONE WebServer 6.0), whereas hitting
http://www.apache.org/images/asf_logo_wide.gif;jsessionid=foo
results in a 404 (Apache/2.0.48-dev (Unix)). Same here ;-) (Microsoft-IIS/6.0)
http://www.microsoft.com/homepage/gif/bnr-microsoft.gif;jsessionid=foo
You might try something like:
<body background="<c:out
