Need help with shutdowning a java process

[Yevgen Krapiva]

Thanks, I've already read the article but still missing some things.
So, I've followed your advice:

Now rc script looks like:

pidfile="/var/run/${name}.pid"
command="/usr/sbin/daemon"
command_args="-p ${pidfile} $runcmd"
command_interpreter="/usr/local/diablo-jdk1.6.0/bin/java"
#flags="-p ${pidfile} $runcmd"

Testing script:

root at etc/rc.d #./openjsip-location-service onestart
./openjsip-location-service: WARNING: no shebang line
in /usr/sbin/daemon
Starting openjsip_location_service.
2010-01-06 06:34:13,813  INFO  - Location Service started...

root at etc/rc.d #./openjsip-location-service onestatus
./openjsip-location-service: WARNING: no shebang line
in /usr/sbin/daemon
openjsip_location_service is not running.

root at etc/rc.d #ps wwaux | grep openjsip
root       19814  0.0  0.7 894148 22688  ??  Is    8:34AM

What means "no shebang line" ?

Ok, when I comment command_interpreter line, no warnings are issued.
But checking status is also not working. Running sh -x
openjsip-location-service showed that:
 + _pidfile=/var/run/openjsip_location_service.pid
 + _procname=/usr/sbin/daemon
 + _interpreter=''

So, procname is incorrect. No daemon in processes, there is java only.
So, I'm trying to set correct process name:

# Subvert the check_pidfile procname check.
if [ -f $pidfile ]; then
  read rc_pid junk < $pidfile
  if [ ! -z "$rc_pid" ]; then
    procname=`ps -o command= $rc_pid`
    echo rc_pid=$rc_pid
    echo procname=$procname
  fi
fi

Testing:

root at etc/rc.d #./openjsip-location-service onestatus
rc_pid=24821
procname=/usr/local/diablo-jdk1.6.0/bin/java
-cp :/usr/local/share/openjsip/lib/jain-sdp-1.0.115.jar:/usr/local/share/openjsip/lib/jain-sip-api-1.2.jar:/usr/local/share/openjsip/lib/jai
./openjsip-location-service: WARNING: no shebang line
in /usr/local/diablo-jdk1.6.0/bin/java
openjsip_location_service is not running.

Running with sh -x showed that:

+ _pidfile=/var/run/openjsip_location_service.pid
+ _procname=/usr/local/diablo-jdk1.6.0/bin/java
+ _interpreter=-cp

May be I should simply override stop_cmd and kill process manually using
PID only ?
