I was able to solve this problem in Eclipse, and I am not sure of the analogous solution in NetBeans though it isn't important to me at this point. Simply importing a JAR file is not enough to claim its functionality. It must be added to the Interpreter Libraries.
Window -> Preferences -> PyDev -> Interpreter - Jython -> New Folder (I did New Jar/Zip(s) as well, I assume either would solve the issue) and point to the directory (or JAR).
