Java global hotkeys without use of JNI?

Hey, I'm looking for a way to set some global hotkeys in Java without writing code native to each OS. This application is meant to be cross-platform in its purest sense.

The program will be minimized and will be performing actions with the mouse and keyboard. Obviously, the user can't open the program again to stop it, so a global hotkey (shift+F11 or something) is needed.

Anyone know where I can start looking?

The API for low level keyboard hooks are different for each OS and I believe global hooks break javas security model. You'll have to provide native hooks for each OS you want to support

Found a good library that does it for me, @Jiwi linked it to me but deleted his reply for some reason.

Yeah I didn't see that the library I linked already took care of the cross-platform recoding issues Blu was worried about with JNI. Figured it was useless to link at first, but it creates separate code for each platform so that's nice I suppose

JNativeHook leverages platform-dependent native code through Java's native interface to create low-level system-wide hooks and deliver those events to your application.

You'll have to use JNI.

If we use Windows has an example, because when you click a keyboard character on Windows,
Windows dispatches a message to the message queue.

You can hook these natively using WinAPI but the JVM has no built in facilities for doing this as it differs per platform greatly.
The only thing you can hook in Java for keyboard shit is focused Java GUI AWT components where the event queue has to process all of the characters.
The JVM isn't globally caring for whatever messages/events Windows itself dispatches.

Hope this was useful,
