I added "-l" parameter to line 64 /bin/su -l $TOMCAT_USER -c $CATALINA_HOME/bin/startup.sh to load user environment

update tomcat_pid() to work on OS X
tomcat_pid() {
echo ps -fe | grep $CATALINA_BASE | grep -v grep | awk '{ print $2 }'
}

The script does a potential infinite wait on startup. I think the script should fail if tomcat does not start up before a timeout.
For example it happened that I have configured Tomcat on a port different than 8080, set the boot script to run on startup without changing the port in the script and then I got locked out of my server, because chkconfig put Tomcat before even ssh :-(

Suppose Tomcat does not start for a reason someday (e.g. problems with file system, permission, etc), it won't probably open the port and the entire boot sequence may be at jeopardy if the script loops on curling the port

Hey,Thank for your perfect script.
But I have found a bug:
You get the tomcat pid by

echo ps -fe | grep $CATALINA_BASE | grep -v grep | tr -s " "|cut -d" " -f2

But if I have opened a conf file in the $CATALINA_BASE ,the command will return more than one result.

you can change it to

echo ps -ef | grep "org.apache.catalina.startup.Bootstrap start" | grep $CATALINA_BASE | grep -v grep | tr -s " "|cut -d" " -f2

Thank you!
(My English is not good,if inappropriate,please understand.)

Hello, Thanks for your script.
One thing i want to check some.
tomcat_pid method
echo ps -fe | grep $CATALINA_BASE | grep -v grep | tr -s " "|cut -d" " -f2

When i stop tomcat, sometimes process shows more then 1. so It cause many pid lists.

So, I recommand tomcat_pid scripts change below
echo ps -fe | grep $CATALINA_BASE | grep -v grep | grep -v stop | tr -s " "|cut -d" " -f2

Thank you!

The tomcat status function should be exit 3 instead of return 3.

return has nothing to do with exit codes required for application/scripts.

thanx for the script!
