# 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 3.5.12 of the Wrapper.

# Paths
# Note that (percent)INSTALL_PATH and (percent)SYSTEM_java_io_tmpdir
# should have been replaced by the izpack installer.
# If you did not run the installer, replace them with the appropriate path.
I2P="%INSTALL_PATH"
I2PTEMP="%SYSTEM_java_io_tmpdir"
# PORTABLE installation:
# Use the following instead.
#I2PTEMP="%INSTALL_PATH"

# Application
APP_NAME="i2p"
APP_LONG_NAME="I2P Service"

# 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.

# FIXED_COMMAND tells the script to use a hard coded action rather than
# expecting the first parameter of the command line to be the command.
# By default the command will will be expected to be the first parameter.
#FIXED_COMMAND=console

# PASS_THROUGH tells the script to pass all arguments through to the JVM
#  as is.  If FIXED_COMMAND is specified then all arguments will be passed.
#  If not set then all arguments starting with the second will be passed.
#PASS_THROUGH=true

# 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, wait for the wrapper to report that the daemon has started

# 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 set, the 'pause' and 'resume' commands will be enabled.  These make it
#  possible to pause the JVM or Java application without completely stopping
#  the Wrapper.  See the wrapper.pausable and wrapper.pausable.stop_jvm
#  properties for more information.
