While I'd simply suggest downloading the 1M data set (or 10M if you
want to play with an even more realistic amount of data), yes it's not
hard to simply look for in the project, and
swap out GroupLensDataModel for FileDataModel. Just a one-line change.

Does this work on Windows? yes... though I admit any time I have used
Windows, I have used Cygwin in order to have a Unix-like environment,
with bash and all. I am not entirely sure how this would work in a
native Windows shell, but there must be an equivalent. It would work
to set an environment variable in the control panel but probably an
easier way.

The example here actually uses Jetty instead of Tomcat, via a Maven
plugin. It's all pretty automatic; there's nothing more than what's in
the instructions.

But the .war file that is generated would run on any J2EE container,
including Tomcat. You can easily use the targets in 'taste-webapp' to
build a deployable product around a Recommender implementation.
