Hi gurus

I would like to develope a java appliction which goes and sits in system
tray like yahoo and msn messanger.
I am also aware that java cannot manipulate system resources also the fact
that all the operating system dos not have system tray. I might have to use
JNI for that.

But i m not comfortable with that. Can anybody suggest me anything for this
For that matter i would appreciate if anyone can just mail me the JNI "hello
world" code which will gimme some direction

Thanks
