To clarify, I was responding to a question as to whether a JAR file
*contained* a tag library, not that it used one. Big difference.

I agree with Chris Cheshire: check the ZIP contents list and not a
binary check. Though the ZIP filenames are stored (mostly) in the
clear, it's possible that you might get unlucky. Also make sure you
use a case-insensitive check.

Searching for .tld files ought to do it.
