Is that directory inside the deployment directory of your webapp? Don't
do that!

What does REFRESH do in Eclipse? Does it re-deploy/reload the webapp? If
so, then you're hitting Tomcat's directory-caching behavior which makes
it difficult to put new files into the deployment directory while Tomcat
is running. Again, don't do that!

Put your files somewhere else, and map a URI in your web application to
a servlet that can fetch the files (and/or directory listings) from that
other directory.
