Q:

How to use Apache Logger or Log4J in Coldfusion MX

Is there any source available which shows how may I use Logging functions in ColdFusion? 
Or is there any Logger available in ColdFusion?

A:

I am not sure you can use Log4j but whey don't you try Logbox (http://wiki.coldbox.org/wiki/LogBox.cfm). I had tried with coldbox framework but work without  framework as well.
