How do I extend application.cfc

My current attempt at extending m application.cfc results in this message:

The folderA.subfolderB.///Application component or interface cannot extend itself.

I have a folder named "folderA" and within this folder is an application.cfc and a subfolder named "subfolderB'  Within subfolderB I also have an application.cfc

The code within folderA/application.cfc is as follows:

<cfcomponent>
    <cfset this.name               = "test1">
    <cfset this.sessionManagement  = "true">
    <cfset this.clientManagement   = "false">
    <cfset this.setClientCookies   = "true">
    <cfset this.applicationTimeout = CreateTimeSpan(2,0,0,0)>
    <cfset this.sessionTimeout     = CreateTimeSpan(0,0,20,0)>
</cfcomponent>

The code within folderA/subfolderB/application.cfc is as follows:

<cfcomponent extends="../Application">
    <cfset this.name               = "test1">
    <cfset this.sessionManagement  = "true">
    <cfset this.clientManagement   = "false">
    <cfset this.setClientCookies   = "true">
    <cfset this.applicationTimeout = CreateTimeSpan(2,0,0,0)>
    <cfset this.sessionTimeout     = CreateTimeSpan(0,0,20,0)>
</cfcomponent>

What value do I need in the 'extends' in order to have the subfolderB application.cfc extend the application.cfc located in the parent folder?  Can it be a relative path?  Does it have to be a mapping to the parent folder?

Thanks,
