# launchAppManRSL.py (Jython)
#
# Launches an Application Manager, uploads and runs printenv.py.
# Version 2:  uses appMan.sh ("batch-adapted").
#
# Since we must pass parameters directly to the 
# appMan.AppManComponent call, we cannot use the cca module's 
# "createComponent" method, but must directly construct the
# RSL and use it to invoke Gram.request.
#
# Given that this is simply for demonstration purposes, we
# do not set any of the arguments necessary for a batch run,
# and we submit the job interactively rather than through the
# batch jobmanager.
#
# Arguments to appMan.AppManComponent:
#
#  [1]   = host
#  [2]   = job id
#  [3]   = path for python script
#  [4-n] = parameters for python script (here, none)
# 
# Example code by Albert L. Rossi, IU Extreme! Computing
# December 2001
