Unable to stop Tomcat

Question

I am very new to Tomcat and just configured my tomcat with jprofiler. But now unable to stop tomcat server, getting the following error message.

[root@localhost bin]# service tomcat stop

\n\nTomcat has shutdown

I am not sure what is wrong in my configuration and yes firewall is disabled on the box.

[root@localhost bin]# service iptables status
Firewall is stopped.

Solution

In order to find tomcat PID run:

ps -ef | grep tomcat

then use this command:

kill -9 PID

Or in one command:

kill -9 $(ps -ef | grep tomcat | grep -v "grep" | awk '{print $2}')

Another thing, you might have a watchdog running that keeps bringing tomcat back up - in such case you'll want to turn off (or kill) the watchdog as well
