How do I stop all running instances of Tomcat?

["Address already in use" error running Tomcat on Apache

I'm running Tomcat 3.2.2 through an Apache 1.3.19 server on a Linux box. I shut down Tomcat; when trying to restart, I get the error msg "Address already in use". I read the thread on this topic telling me to fully stop other instances of the servlet engine or another service before restarting Tomcat.

The problem is that I'm a Linux newbie, so don't know how to make sure that other instances or servers are fully stopped. Doing a lot of flailing about here. Help!]

Try doing a "ps -ef | grep java" (I think -ef can work under linux as well). This should give you the tomcat process. Do a "kill -9 #PID" to kill the tomcat process. You have to be root or PID owner to do this.

I have experienced this myself while using different unix shells to stop and start. Try sticking with the same shell next time.

Try lsof command to list open sockets and their associated executables. On windows you can use the fport tool.
