Subject RE: Shutting down one instance of tomcat 6 from a listener
Date Mon, 15 Nov 2010 09:37:20 GMT
That's it! I have a single Tomcat/JVM instance but multiple applications running on it.
In fact with System.exit(1) Tomcat is not completely stopped; it is still running but it hangs.
I have to kill the process to terminate it.

So, how to shut down properly the current application from a 'listener' leaving the other
webapps deployed into Tomcat to continue their business?

I was unsuccessful looking for some source code to do so.

No problem: we can work around language difficulties. More explanation usually helps.

The number of CPU cores should not affect the number of instances that you have.

So, it sounds like you have a single Tomcat/JVM instance but multiple applications running
on it. You want to have one of your webapps check some configuration and gracefully stop if
there is a problem, leaving the other webapps deployed into Tomcat to continue their business.

If that's the case, then calling System.exit will certainly cause Tomcat to become "unstable",
where "unstable" means completely stopped.
