List Files in a Java Web App
Put this into your web.xml and override so the default servlet configuration declared by every Servlet Container (Tomcat, Jetty, GlassFish):
<servlet>
<servlet-name>default</servlet-name>
<init-param>
<!--boolean paramter to allow directory traversal-->
<!--this parameter name depends on the specific servlet container implementation-->
<!--valid for Jetty, Tomcat uses a different parameter-->
<param-name>dirAllowed</param-name>
<param-value>false</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>default</servlet-name>
<!--folder name in the "webapp" folder-->
<url-pattern>/static/*</url-pattern>
</servlet-mapping>
