# Java Service Wrapper sh script. Suitable for starting and stopping
# wrapped Java applications on UNIX platforms.

# These settings can be modified to fit the needs of your application
# Optimized for use with version 3.3.6 of the Wrapper.

# If uncommented, causes the Wrapper to be shutdown using an anchor file.
# When launched with the 'start' command, it will also ignore all INT and
# TERM signals.
#IGNORE_SIGNALS=true
# Wrapper will start the JVM asynchronously. Your application may have some
# initialization tasks and it may be desirable to wait a few seconds
# before returning. For example, to delay the invocation of following
# startup scripts. Setting WAIT_AFTER_STARTUP to a positive number will
# cause the start command to delay for the indicated period of time
# (in seconds).
#
WAIT_AFTER_STARTUP=0
# If set, the status, start_msg and stop_msg commands will print out detailed
# state information on the Wrapper and Java processes.
#DETAIL_STATUS=true
# If specified, the Wrapper will be run as the specified user.
# IMPORTANT - Make sure that the user has the required privileges to write
# the PID file and wrapper.log files. Failure to be able to write the log
# file will cause the Wrapper to exit without any way to write out an error
# message.
# NOTE - This will set the user which is used to run the Wrapper as well as
# the JVM and is not useful in situations where a privileged resource or
# port needs to be allocated prior to the user being changed.
