Need Help Finding ColdFusionMX/wwwroot/WEB-INF/classes in JRun

I am trying to copy some class files into Jrun4 however the instructions are for the standalone install of ColdFusionMX. And I have 14 instances of WEB-INF and I am not sure where to place the files. Here are the instructions.

Copy FriendlyURLServlet.class, FriendlyURLServlet.java, FriendlyURLData.class, FriendlyURLData.java, and FriendlyURLs.txt to <cfusionmx>/wwwroot/WEB-INF/classes.

Ensure you have the following entries in <cfusionmx>/wwwroot/WEB-INF/web.xml

<servlet>
<servlet-name>FUServlet</servlet-name>
<display-name>FriendlyUrlServlet</display-name>
<description>Translates friendly URLs to objects</description>
<servlet-class>FriendlyURLServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>FUServlet</servlet-name>
<url-pattern>/go/*</url-pattern>
</servlet-mapping>

If you want to make your own modifications to the servlet and data classes you might also want to add the following entries to <cfusionmx>/wwwroot/WEB-INF/jrun-web.xml

<reload>true</reload>
<compile>true</compile>
