A while back I found out that CFMX compiles ColdFusion Components and I was curious as to where they were stored. I found two locations where they were kept:

<your drive>:\CFusionMX\wwwroot\WEB-INF\cfclasses
<your drive>:\CFusionMX\wwwroot\WEB-INF\cfc-skeletons

<your drive>:\JRun4\servers\<instance name>\cfusion-ear\cfusion-war\WEB-INF\cfclasses
<your drive>:\JRun4\servers\<instance name>\cfusion-ear\cfusion-war\WEB-INF\cfc-skeletons

I am not sure what the differences are between the two folders and usually I find the compiled components in cfclasses folder [only once so far have I found one im cfc-skeleton]. Once compiled the CFC seems to be compiled into a one generic class file and then another one for each function in the CFC.
