OK, but in this case why even use a mapping? You don't need to. You can just
invoke "components.subFolder.myCFC" and be done with it.

Again, I don't see what this saves you, since you first have to know the
path to the components folder (in this case, "components"), you stilll have
to know the path from that component folder to the target CFC ("
subFolder.myCFC"), and you have to manually copy the getCFC.cfm file into
the correct folder. In other words, you have to know the same information to
do this that you would just to call the component directly ("
component.subFolder.myCFC"). I think I might still be missing something in
what you're describing, because so far this approach doesn't seem to be
doing much.

Maybe this is what you're missing, because you don't need to have a mapping
in this example to use ColdSpring or just to call the components yourself.
