How can I turn listings on for just one folder in my webapps, as opposed to every folder

At the moment I have listings enabled(see code below) which means everyfolder is affected. how can i make it so that only webapps/myProject/myFolder is listable?

<init-param>
        <param-name>listings</param-name>
        <param-value>true</param-value>
</init-param>

I have looked at this document but i do not understand it. can someone help please.

edit: my local web.xml

Instead of modifying the web.xml under $CATALINA_BASE/conf/web.xml, put the below configuration in your local web.xml.

<servlet>
    <servlet-name>default</servlet-name>
    <servlet-class>
      org.apache.catalina.servlets.DefaultServlet
    </servlet-class>
    <init-param>
        <param-name>debug</param-name>
        <param-value>0</param-value>
    </init-param>
    <init-param>
        <param-name>listings</param-name>
        <param-value>false</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

...

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>/path/to/listabledir</url-pattern>
</servlet-mapping>

The key here is the line <url-pattern>/path/to/listabledir</url-pattern>.

The Tomcat Wiki should give you some reference.
