local WEB-INF/web.xml

[Paul_Wallace]

Hello
        Why when I add:

         <listener>
 <listener-class>LoadMycompServletAtStartup</listener-class>
        </listener>

to a sparsely populated local web.xml file (webapps/mydir/WEB-INF/web.xml) 
does the system fail - 404 error?. Without this addition, the page loads.
The servlet 'LoadMycompServletAtStartup' is located: 
webapps/mydir/WEB-INF/classes/LoadMycompServletAtStartup.java. Must a 
specific path or URL to the file be defined? The syntax above is the only 
addition made since the installation of Tomcat. 

Thanks

paul.
