Since I just figured it out, I thought it might be helpfull to others too:

<cfadmin action="updateGatewayEntry" type="server" password="server-admin-password"
	startupMode="automatic"
	id="name-of-the-event-gateway"
	class=""
	cfcpath="railo.extension.gateway.DirectoryWatcher"
	listenerCfcPath="path.to.your.DirectoryListener"
	custom='#{
		  directory="/private/etc/apache2/"
		, recurse=false
		, interval=2000
		, extensions="conf"
		, changeFunction="onChange"
		, addFunction="onAdd"
		, deleteFunction="ondelete"
	}#'
	readOnly=false
/>

<!--- remove the directorylistener --->
<cfadmin action="removeGatewayEntry" type="server" password="server-admin-password"
id="name-of-the-event-gateway" />
