# This is an interface which allows java servlets
# to be run from the cgi-bin directory
#
# This script will do the following:
#  1) Determine if a process is listening to your port $PORT.
#     If so, then your servletrunner is already running.
#  2) If necessary,  start the servletrunner server the selected port
#  3) redirect the URL of the current request to your servletrunner

# Define the port where your server will listen
# Port numbers should be between 10000 and 65535
# Use the same port for all of your servlets
# Each user should have a unique port number
PORT=65535

# Define user's servlet directory
# Change this to your own servlet directory
SERVLET=/usr/faculty/schmitt/servlet

# Below this line should not normally require editing
