Tapping into ColdFusion MX 6.1 Logging

[howbizr]

This isn't a question... but a record of my experience for anyone else
doing this. In my googling on this topic, I didn't find many answers,
so here's what I came up with.

I discovered... 6.1 has pretty old Log4J, v1.1.3. Thankfully, it's
open source, and very readily available, despite being an old version.
So that helps.

As far as I can tell, if you just want to use the old logger, and hope
that ColdFusion picks up your stuff, do something like this...

public static Category logger =
Category.getInstance(MyClass.class.getName());

if(logger.getChainedPriority().isGreaterOrEqual(Priority.DEBUG)) {
logger.debug("My debug message");
}

And if you want to interface with ColdFusion's logger directly
(tapping into cfusion-out.log), try this...

private static Logger logger = LoggerService.createDefaultLogger();

if(logger.isDebugEnabled()) {
logger.logDebug("My debug message");
logger.flush();
}

And I did find there's a logger.xml file out there, supposedly for
adding custom definition. I haven't had much success with it, but
here's the path for those that might be interested. This does vary
slightly per install, but it gives you a starting place.

C:\JRun4\servers\cfusion\cfusion-ear\cfusion-war\WEB-INF\cfusion
\logger.xml

Last thing, also undocumented, also very useful. You can enable more
debugging in the logs...
C:\JRun4\servers\cfusion\SERVER-INF\jrun.xml

Find this service and change "debugEnabled" to "true"...
