You are not trying to make sure if tomcat is really started. Start tomcat using this script, and try to stop it immediately. There is a good chance you will see errors.

It needs to check the instance of Tomcat running. I will suggest adding another grep in the pid checking function:
grep "catalina.home=$TOMCAT_HOME"

Ideally, maintaining a pid file is not a bad idea.

Hey there starsid, take a look at my fork: https://gist.github.com/miglen/5590986
I'm using CATALINA_BASE for finding the PID of the project.

The catalina.sh script already has this functionality - if you provide a filename via the CATALINA_PID environment variable, it will save the pid in that file. Then, when you stop it, you can call it with '-force' and it will kill it if necessary.
