Good morning folks!

I'm trying to add Maven to the system boot by the moment without success.
Testing the operation of the script I realize that the process isn't persistent when the program is launched with the start option.

---- #Startup Script ----
#! /bin/sh
# chkconfig: 345 99 1
# description: xxx
# processname: Application
#
. /etc/rc.d/init.d/functions

BIN="/projects/user/app/appsysv.sh start $VERSION"
PIDFILE="/projects/user/app/pid.file"
#LOG
LOGFILE="/projects/user/log/app.log"

start()
{
su - user -c "/etc/init.d/app start_internal" &
echo -n "Starting App ... "
echo
}

start_internal()
{
# Remember PID
echo $$ > $PIDFILE
# Exec application
exec $BIN >> $LOGFILE 2>&1
if [ $(cat $PIDFILE) -gt 0 ]; then
ps -p $(cat $PIDFILE) > /dev/null
if [ $? -eq 0 ]; then
echo "App started successfully"
fi
fi
}

stop()
{
if [ -f ${PIDFILE} ]; then
kill $(cat $PIDFILE)
echo -n "App stopped"
echo
fi
}

case "$1" in
start)
start
;;
start_internal)
start_internal
;;
stop)
stop
;;
restart)
stop
start
;;
*)
echo "Usage $0 {start|stop|restart}"
exit 1
esac

And this is how the application is natively launched out of the system startup (the script which i'm pointing):

#!/bin/sh

#Set Maven
export M2_HOME=/opt/apache-maven-2.2.1
# Set Java environment
export JAVA_HOME=/opt/jdk1.6.0_22

nohup mvn -e -o -Dapp.version=$1 -Dnbis.env=$ENV -Dlocal.server.file.locn=$LOCAL_SERVER exec:java > /projects/user/log/app-out.log 2>&1 &
}

stop()
{
if [ -f ${PIDFILE} ]; then
kill `cat $PIDFILE`
echo -n "App stopped"
echo
fi
}

case "$1" in
start)
start $2
;;
stop)
stop
;;
restart)
stop
start $2
;;
*)
echo Usage:
echo $0 'start [App_version]'
echo 'or restart [app_version]'
echo 'or stop'
exit 1
esac
exit 0

Can anybody help to find out what's happening? When I check for the process, I find that the pid has changed in the pid.file but the process isn't running

Thank you so much.
