We may be going around in circles here, but:

What was the URL you tried?  mydomain.com/tst/foo/bar/myServlet?  And
what is the full text of the tomcat log 404 error message?

Also, I note you have "Web-inf" in the full path of your
servlet/classes directory below -- is that really what it is, or are
you just being lazy typing "WEB-INF" (because I believe it's supposed
to be ALL CAPS)?

Not sure what else to suggest at this point.  Must be some little
thing we're missing.
