I'm not sure this is a config issue in CF Admin?
I think what determines whether files (.css, .js, .class,
.jar, etc) can be accessed
via URL is the Web Server?
I'm new to CF and I'm not sure how it all works but it seems
to me that CF is out
of it when it comes to retrieving non-cfml files?
Meaning, if a user's browser/applet/webpage is trying to
retrieve a .jar or .class from the Web Server, the CF engine does
not even know that the request for the .jar or .class or .js or
.css has been made.
The Web Server should simply return the requested resource
from disk without
further processing or handing it off to some other processing
engine.
So if you leave CF out of it, perhaps the thing to
investigate is why the Web
Server does not appear to be able to serve-up files under the
CFIDE/... directory?
Anyway, sorry I have not been any help.
Good luck!
