I haven't been able to find much documentation of anyone trying to use jython with the gnuradio software, but my issue seems very basic.  The included modules in the open source software are not being detected for whatever reason because no matter what I append using sys.path.append(), an ImportError is the result.  What is the correct procedure for including these modules?  Here are the import statements:

import sys
from gnuradio import gr, gru, eng_notation, optfir, window
from gnuradio import audio
from gnuradio import usrp
from gnuradio.eng_option import eng_option
from optparse import OptionParser
from usrpm import usrp_dbid
import math
import time
import struct
