Using the url http://localhost/ibi_apps/ calls the welcome.jsp script. Using the url http://localhost/ibi_apps (without the /) displays a 404 error.
We've created directories below ibi_apps (http://localhost/ibi_apps/test) that allow directory browsing and do not have a default page. How do we setup the proper controls to protect against directory browsing and allow automatic loading of a page?

This doesn't seem to work for me, but the doc says to change the conf/web.xml file. Change the listings param value from true to false:

  
    <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>

what documentation are you referring to?
