Right, I didn't define the plugin.
It works

So far I'm happy.
now I just need to find out how to differentiate the input...Keyboard and mouse is all the same, but a gamepad has its own name.
Is there any device ID to read out... I mean the OS can differentiate between two mice, and with default Plugin JInput too. But with JInput the name of the mouse might be the same (HID compliant mouse for both) and its no problem for JInput to know which does what.
To save some space: where do I find something like a TODO list and what has changed in the last time, so I don't have to ask each time.
