Ben Nadel's POI utility is nothing more than a CFC/custom tag
wrapper to the POI library included with ColdFusion. It's still all
Apache POI code behind-the-scenes.
Apache POI is an open-source Apache-license Java library. It
has nothing to do with the Apache Web Server, other than being
licensed under that foundation (the Apache foundation).

Like I said, a version of Apache POI is already included with
ColdFusion. Go to your installation directory and look in lib. On
CF8, there is:
poi-2.5.1-final-20040804.jar
poi-contrib-2.5.1-final-20040804.jar
The newest version of POI is 3.1, released on 6-29-2008. I
haven't had any problems removing the POI included with CF and
replacing it with the newer version, but your experience may
vary.
