In version 4.1.12 of Tomcat, the invoker servlet (the one that handles
"/servlet/*" paths) got disabled by default for security related reasons.
Although you can re-enable it by uncommenting the appropriate
<servlet-mapping> in the default configuration file
($CATALINA_HOME/conf/web.xml), you are much better off creating explicit
mappings for each of your servlets in the web.xml file. For example, a
mapping for the servlet you defined above, which maintains existing URLs,
would look like this:
<servlet-mapping>
<servlet-name>Group</servlet-name>
<url-pattern>/servlet/s_authentication.Groups/*</url-pattern>
</servlet-mapping>
Remember that the order of elements in web.xml is required to match the
DTD, so put all your servlet mapping elements *after* the servlet
elements.
(Of course, you can also use servlet mappings to map *any* legal URL to a
particular servlet, but doing the above is easiest in a conversion case.)
