How to shutdown java application correctly from C# one

Question

I have java application which shutdowns correctly when i use CTRL-C, java application saves all data before shutdown. Now i trying to shutdown this java application from my C# console application using Process.Close(), but application dont't save any data when i use this, i also tried Process.CloseMainWindow() but using this nothing is happening, and also Process.Kill() but using this process just killed, without any savining.

How can i raise shutdown hook on java application from C# console application?

do you already have a shutdown hook in your app and Process.close() does not trigger it? — Denis Tulskiy

is your shutdown hook executed when you end the program from task manager? if so, you can try posting WM_QUIT or WM_CLOSE messages to your java process. — Denis Tulskiy

A shutdown hook cannot be raised by another app.

The shutdown hook runs when:

A program exists normally. For example, System.exit() is called, or the last non-daemon thread exits.
the Virtual Machine is terminated. e.g. CTRL-C. This corresponds to kill -SIGTERM pid or kill -15 pid on Unix systems.

The shutdown hook will not run when:

the Virtual Machine aborts
A SIGKILL signal is sent to the Virtual Machine process on Unix systems. e.g. kill -SIGKILL pid or kill -9 pid
A TerminateProcess call is sent to the process on Windows systems.

How can i send CTRL-C signal to java application

David Kroukamp Over a year ago

I would suggest rather trying to kill the process using cmd? I cannot however say for sure it will work, see here for more: techmonks.net/… you'll have to test it, Though a draw back would be your jar's portability.
