Because if you assign a null path to your chosen servlet you will not be
able to serve anything else from this context from Tomcat.
I did not actually try it, but I assume that if you do
<servlet-mapping>
<servlet-name>someServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
i.e., when you map a servlet to / then each and every URL mapped to this
context and served by Tomcat will result in serving the someServlet.
Out goes packages, hierachy, JSPs and subdirs...
Of course, it has its uses (e.g., with MVC paradigm, when each URL goes
to a servlet, and then servlets forwards it to other stuff using forward call
within the container), but I suspect this was not a goal here, was it?
That is why I said what I said...
So the way to do it is to use mod_rewrite. In your httpd.conf you would put
something like:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^/demo$ /demo/servlet/someServlet [R]
RewriteRule ^/demo/$ /demo/servlet/someServlet [R]
</IfModule>
And this will rewrite the URL
http://whatever.com/demo
http://whatever.com/demo/
to
http://whatever.com/demo/servlet/someServlet
while it leaves other stuff alone... This way you do not remap all your
context to a single servlet, but you just remap the single URL.
