broken link for me?

This is not the right language for a keylogger, you should write one in c++ or c, considering you can use global hotkeys, which you can't in JAVA, if you really want to make a c++ or c keylogger all you need to do is make a basic server to client and client to server socket, then you should send over a packet containing the recent key typed from the client, in the server you recive it and then it reads the packet and prints it out. or prints out to a GUI.

Yeah broken link.
