To use the /servlet/ notaton you will need to enable the invoker servlet. To do this open the conf/web.xml and search on "invoker". Follow the directions.
An alternative would be to map the servlet to a url and use that url to call the servlet
<servlet>
<servlet-name>TestServlet</servlet-name>
<servlet-class>TestServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/TestServlet</url-pattern>
</servlet-mapping>
now you should be able to access the servlet with /Fortune/TestServlet
