What I want is extremely simple.  I want to install the Zxing library somewhere in my Processing folder (or system variables), so that I can use the com.google.zxing namespace.  So far, I've tried putting core.jar and javase.jar (from the Zxing library) in the following places:

Processing/lib

Processing/libraries

Processing/sketchbook/[application_name]/libraries

Nothing works.  I'm at an impasse here -- I have no idea what to do.

Thank you for your time!
