Cannot get SSI to work on Tomcat 4.0.2

[Eric Ace <AC...@rdacorp.com>]

I justdownloaded and installed Tomcat 4.0.2. I am trying to have an html page do an SSI of a separate shtml. I am running Win2K, Java Standard Edition 1.3.1_01. I have scanned the list and can't see why this shouldn't be working...
 
Here's what I'm doing:
 
File "main.html" contains the text:
 
<!--#include virtual="/hdr.shtml" -->

Per release notes, I have:
 
1. Uncommented the ssi servlet declaration in \jakarta-tomcat-4.0.2\conf\web.xml
2. Uncommented the mapping for the ssi servlet in the aforementioned web.xml file
3. Renamed the file \jakarta-tomcat-4.0.2\server\lib\servlets-ssi.renametojar to
    \jakarta-tomcat-4.0.2\server\lib\servlets-ssi.jar.

 
My web app is installed under the webapps directory in a folder called "irt". So, the full path of the main.html file above is "\jakarta-tomcat-4.0.2\webapps\irt\main.html", and the file I'm trying to include is "\jakarta-tomcat-4.0.2\webapps\irt\hdr.shtml".
 
I must be doing something obviously wrong because it simply does not work. There are no errors. Nothing in the logs. I look at the source coming down to the browser and the include directive is being passed directly through. Yet if I hit that page directly in the browser URL the page is in fact retrieved:
 
http://localhost/irt/hdr.shtml
 
Help is much appreciated...
