Programmatic instruct Tomcat to shutdown

Hello,

I would like to forcefully cause my application server to fail once I
discover a situation I can't recover from. We have HA that should handle the
situation from there.

The best way I can see this happening is by issuing a shutdown instruction
to the container, but I can't find how to do this "peacefully". I tried the
System.exit(1) trick but this keeps running threads active because they do
not get the shutdown notification.

How should I properly call server shutdown from my webapp ?


Thank you,
Maxim.

Not quite.

I've commented that I've tried System.exit(1); and it's fails because I have
threads that aren't going down by this instruction. The need the Servlet
notification of a shutdown event.

That's the reason for my query of doing "ordered shutdown".

Thank you for your help.

You should check out the code for the Bootstrap class:

http://svn.apache.org/repos/asf/tomcat/tc6.0.x/tags/TOMCAT_6_0_18/java/org/apache/catalina/startup/Bootstrap.java

It calls o.a.c.s.Catalina.stopServer which you can read here:

http://svn.apache.org/repos/asf/tomcat/tc6.0.x/tags/TOMCAT_6_0_18/java/org/apache/catalina/startup/Catalina.java

Basically, it makes a localhost socket connection and send the
"shutdown" command to the server. You could do this yourself to initiate
a graceful server shutdown.
