Script used to start/stop and get status of a Tomcat server.

##########################################
# Utility script for tomcat start/stop 
# based on pid file.
# 
# This script will start tomcat and tell to tomcat 
# to create pid file in CATALINA_HOME/bin folder.
#
# Usage [start|status|stop] [tomcat_home_path] [pid_file_name (optional)]: 
# Start tomcat  : tomcat_util.sh start /var/tomcat_home my_pid_file.pid
# Tomcat status : tomcat_util.sh status /var/tomcat_home my_pid_file.pid
# Stop tomcat   : tomcat_util.sh stop /var/tomcat_home my_pid_file.pid
#
# Stop function will ask tomcat to normally stop, then if after 30 seconds 
# tomcat is alive, ask with a kill tomcat_pid and then a kill -9 tomcat_pid
# if still alive.
