Servlet mapping doesn't work after upgrading from Tomcat 5 to 6

[Dharamshila Khandelwal]

Hi,

I have the following servlet mapping in webapps/<webapp>/WEB-INF/web.xml

  <servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>

This mapping worked fine with Tomcat 5, but when I am running the
application with the same mapping, it is not able to load the servlet saying
that the requested servlet not found.

Can anyone please help? Please let me know if you have any questions.

Thanks,
DS.
