    The program would need the focus to get the key press.
    You would need JNI code for this app.

    Java's the wrong tool for the job. You need low-level access to the keyboard driver for your platform. Why can't you use a freely available (some are open-source) 3rd party keylogger?

    My suspicion as well, although I was thinking more along the lines of spyware - which isn't something many of us would like to see the forums have a hand in. Of course this could all be legit, but its up to the original poster to prove so.
