Java code to implement control break command

Question

May be this question is too simple, but I am unable to find a solution anywhere.

I am running a webapp in Tomcat on JVM. I need to stop the JVM by invoking Control-Break. I need to do it from within the Java code. I don't know how to do it.

Can you please help me here? Thanks in advance!

Not sure if it will kill the entire JVM, but `System.exit()` will kill the Tomcat server. — musical_coder, Nov 27 '13 at 06:13
Other options include [JMX](http://tomcat.apache.org/tomcat-6.0-doc/monitoring.html) — Elliott Frisch, Nov 27 '13 at 06:15
Thanks! I know about system.exit(). I need to invoke in particular Ctrl_Break from within the Java code. — kajarigd, Nov 27 '13 at 06:17
I'm pretty sure you can't invoke Ctrl_Break like that, and how are you going to target the "correct" console to invoke Ctrl_Break on? — Elliott Frisch, Nov 27 '13 at 06:24
@Elliott I was thinking if I invoke the command from within the code, it will automatically target the containing JVM. — kajarigd, Nov 27 '13 at 06:33

you can always launch another process to do it for you, for example:

Runtime.getRuntime().exec("kill -QUIT <pid>");

updated, changed to -QUIT, I think SIGINT is CTRL-C and QUIT is CTRL_BREAK, in any case you can use kill command to send those signals – Guy Gavriely Nov 27 '13 at 06:50
to get the pid see http://stackoverflow.com/questions/35842/how-can-a-java-program-get-its-own-process-id – Guy Gavriely Nov 27 '13 at 06:58
I ran the command, got the following exception: Executing kill -QUIT 7248 java.io.IOException: Cannot run program "kill": CreateProcess error=2, The system cannot find the file specified – kajarigd Nov 27 '13 at 07:21
