Re[2]: file path problem

[Jacob Kjome <ho...@visi.com>]

Hello Bharanidharan,

/servlet/ is a mapping provided for you by Tomcat.  In fact, take a
look in the web.xml in $TOMCAT_HOME/conf and look for that mapping:

<!-- The mapping for the invoker servlet -->
  <servlet-mapping>
    <servlet-name>invoker</servlet-name>
    <url-pattern>/servlet/*</url-pattern>
  </servlet-mapping>


If tomcat didn't provide this, you would have to set up a mapping for
each and every one of your servlets that you wished to run.  With
this, you can run any servlet in your webapp by naming the servlet
with the full package name.

When you want a more convenient URL to invoke your servlet, you can
provide your own mapping in a similar way as the above example in your
own web.xml.

Keep in mind that the /servlet/ mapping is *not* guaranteed to exist
across containers, although I would imagine that a number of
containers might just copy Tomcat's lead on this to be compatible.
