Tomcat service script for RHEL/CentOS and Ubuntu

# description: Starts and stops the Tomcat
#
# if you are doing tomcat instancing, you might wanna check the CATALINA_PID logic down here to create something more dynamic behavior
# other than that just add this file under /etc/init.d/ as tomcat and use chkconfig to configure
#
# chkconfig --add tomcat
# chkconfig --level 2345 tomcat on
# chkconfig --list tomcat
#
# and use it like service tomcat start|stop|restart|status
