 U_UID=0
 TOMCAT="tomcat_web"
 
 USER=`echo $UID`
 
 if [ $USER == $U_UID ]
 then
 
 TOMCAT_START="/usr/local/tomcat_web/bin/catalina.sh"
 
 case "$1" in
 
 start)
 
         pidnum=`ps -ef | grep java | grep $TOMCAT | awk '{print $2}' | wc -l`
 
         if [ $pidnum -eq 0 ]
 
         then
                 sleep 2
                 action "Starting Tomcat..."  /bin/true
                 $TOMCAT_START $1>/dev/null 2>&1
 
         else
                 echo -e "\e[31mTomcat is running\e[0m"
         fi
         ;;
 
 stop)
 
         pidnum=`ps -ef | grep java | grep $TOMCAT | awk '{print $2}' | wc -l`
 
         if [ $pidnum -ne 0 ]
 
         then
                 sleep 2
                 action "Stoping Tomcat..." /bin/true
                 $TOMCAT_START $1 >/dev/null 2>&1
                 ps -ef | grep java | grep $TOMCAT | awk '{print $2}' | xargs kill -9
 
         else 
                 echo -e "\e[31mTomcat is stopped\e[0m"
         fi
         ;;
 
 restart)
 
         pidnum=`ps -ef | grep java|grep $TOMCAT| awk '{print $2}' | wc -l`
         if [ $pidnum -eq 0 ]
         then
                 sleep 2
