servlet mapping entails which directory you would like your classes to be or to
be named, and where the actual servlet will be.
Also, will it be mapped to a different name? That's typically a good idea, from
what I've read.
i..e here's a blurb from the web.xml file what servlet mapping would look like.
<servlet-mapping>
<servlet-name>chngctrl.ChangeControlUserAcctServletSPCall</servlet-name>
<url-pattern>/chngctrl/ChangeControlUsersSP.jsp</url-pattern>
</servlet-mapping>
that JSP you see is a "fake jsp" the file doesn't exist but that's where the
action file from the form points. It actually calls the servlet instead, under
the hood.
But further up the page, you have to declare the servlet name, i.e.
<servlet>
<servlet-name>chngctrl.ChangeControlUserAcctServletSPCall</servlet-name>
<servlet-class>chngctrl.ChangeControlUserAcctServletSPCall</servlet-class>
</servlet>
you could make a different name for your class from your servlet if you wanted,
but I think most people don't...probably too confusing in the long run.

Thanks for the info. However, I am new to tomcat and servlets and as such
am still somewhat unclear as to the resolution to this problem. Can you
clarify. What exactly is servlet - mapping?
Thanks,
D

The invoker servlet has been disabled in the default config for ages
(because it is evil :). You can enable it at your own risk in conf/web.xml,
but that isn't recommended. Use an explicit servlet-mapping instead.
Having classes in the default package will prevent you from upgrading later
on. You really should put your class in a package.
