How to configure the ColdFusion Eclipse debugger

I'm running the ColdFusion Builder 3 (Express edition) to connect to a locally running ColdFusion 9 server (windows machine).

When I set up the RDS configuration on the CF Builder and click on Test Connection everything is ok.

But when I click on Test Debugger I get the following error:

Could not initialize class coldfusion.log.CFLogs

Is this a problem with CF Builder 3 trying to access the CF 9 server?

According to this Adobe forum post they resolved the same issue by changing the port setting in ColdFusion Builder to the standard HTTP port (normally 80).

I also found this article which details the steps to setup ColdFusion debugging with Eclipse and it also has the port assigned to 80.

UPDATE:

Read this how-to article from Charlie Arehart. While it references older versions I think the same steps still apply and he mentions specific things that must be enabled on your ColdFusion server for it to work. Hope that helps.

And here is a video tutorial from Adobe's blog that steps you through the process as well.
