Hi.
Change the <url-pattern> of your test application, to be exactly the same as the
<url-pattern> of the production application.
And invoke it as "http://yourhost.cpy.com/testvsb/";, followed by the same "rest of URL" as
what you use for the main application.
Brief explanation : the <url-pattern> is *relative* to the "webapp name". The "webapp
name" is the name of your application's directory (in other words, the name of the first
directory level under (tomcat_dir)/webapps/).
.. Except one special case : the "default application" lives under the path
(tomcat_dir)/webapps/ROOT/ (in capitals), but its "webapp name" is "/".
If the above does not work, then show us how the directory structure under
(tomcat_dir)/webapps/ looks like, and which URL you use to access the production application.

I would like to run two versions of the same servlet (same servlet-class, but
with different WAR filename, servlet-name and url-pattern) under a single
instance of Tomcat 6.0.33. Basically, the aim is to run both test and
production versions of the servlet under the same instance. Better to run them
under separate instances, but getting a suitable second instance is proving
difficult. I thought that the same servlet-class would be fine as long as the
servlet-name and url-pattern were different, but does not seem to be enough.
The problem I encounter is that while the production version is deployed by Tomcat just fine, the test version is not loaded. The test version is unbundled in web apps directory and there is a deployment message in the catalina log, but when I point a web browser to the servlet, the result is just HTTP 404 error: "The requested resource (/testvsb/) is not available."
I've been unable to find any kind of useful debugging clues in the catalina
logs, like a servlet deployment or invocation error, but my knowledge of Tomcat
is meagre.
The web.xml files for the two servlets are included below, in case they are of
interest. The init-param sections are the same because I'm still testing out
the two-servlets-in-one-tomcat concept on my laptop.
Any ideas or advice on how to proceed would be appreciated.
