gracefully terminate a JVM on windows if can't ctrl-c shell

[Michael Grove]

hi,

if i start a JVM on windows from one shell (or process), is there a way to
send the equivalent of a ctrl-c to the JVM from another shell or process?
on unix a regular kill gracefully terminates the JVM (shutdown hooks
invoked). on windows, unless i have access to the shell that started the
JVM, i'm not sure how to gracefully stop the JVM. i believe if i started
the JVM through JNI i could use JNI to stop the JVM gracefully (think that's
how JavaService does it) but i need to be able to stop a JVM started by
another process that invokes java.exe directly. i'm hoping i can write a
program that, given the JVM PID, sends a ctrl-c equivalent to the JVM.

ideas? didn't see this covered in a google search, sorry if i missed it.

thanks.

How about "kill -2 PID" ?

Sorry, that won't work under windows...
have you looked at
http://www.latenighthacking.com/projects/2003/sendSignal/ ?

You can call GenerateConsoleCtrlEvent, or write something to wrap around
it. But that will only send a ctrl-c to a process in the same group,
which presumably is ok as it started from the same console...

Hope that helps!

thanks for the link. i was able to modify the source to SendSignal,
replacing every CTRL_BREAK_EVENT with CTRL_C_EVENT, and the program does
what i want. fairly complex - you have to inject a thread into the JVM
process, then send it the CTRL_C_EVENT - but it's the only solution i'm
aware of right now.

thanks again.
