key input Keylistener doesn't work for JOGL

[tragic_xxx]

For some good reason i am using JOGL ....  Every other thing works well, including the static renderings, but the Input key binding doesn't work, I have got no clues why. I am hoping expert eyes inspection would be able to see whats wrong.  I am hoping this code is small enough and clear enough for someone to be able to inspect with ease and no stress
Many thanks

You probably did not notice, but this is the LWJGL forum. It has nothing to do with JOGL. You should probably ask those kinds of questions on the JOGL forums?
