Can you tell what *is* being called? (If you can't tell directly, you
might be able to get more info from the logs, either the tomcat logs
or the apache logs).
And how do you have things set up to get to tomcat, i.e. what is your
context path? It looks like you have two directories in the context
path in the URL (/servlets/VS), and I haven't really seen that before
(not to say you can't do it, of course :-).
I'm guessing that it might be that apache knows to forward
/servlets/VS/servlet/LogonServlet to tomcat, but not
/servlets/VS/servlet/LogonServlet/VLM. If that's the case, you might
have to add some directives to your apache/tomcat httpd.conf file to
get it to work right (e.g. ApJServMount's).

Again, you might be able to do this with some appropriate ApJServMount
directives. It also might depend on how you have things set up with
tomcat, e.g. what the contexts are and what the paths to them are.
Hope this gives you some ideas.
