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@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...

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@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 ?
