<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.jsp::$DATA</url-pattern>
</servlet-mapping>

and then restart the Web Server by executing the following commands as the 'root' user:
# <INSTALL-DIR>/admin-server/bin/stopserv
# <INSTALL-DIR>/admin-server/bin/startserv
where <INSTALL-DIR> is the path to the Sun Java System Web Server installation directory.

Refer to the product documentation for more information on editing the "default-web.xml" file.
