Looks like the system environment may not be set right
for you when shelling out with os.system from a cron job.

PATH and CLASSPATH are likely culprits.  To check this out,
call the env program, redirecting its output to a log file,
right before you try to run jpython; do the same from the
interactive session where things are working; and verify
the differences between the environment in the two cases.
