In the default web.xml of the application server you need to disable the directory listing feature. In case of JBoss AS (specifically: Tomcat) you need to set the DefaultServlet's initialization parameter listings to false:

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