JNI and SetWindowsHookEx Callback not being called?

I seem to have an issue that I cant resolve. I have a jni dll that
calls SetWindowsHookEx with a callback to HookKeyboardProc (basically
a real simple global keyboard hook). Now the dll almost works all the
jni hooks are fine and the program appears to run but the callback
(HookKeyboardProc) does not seem to get executed or possibly never
returns from execution. The code is as follows. None of the
variables being set in the code actually get set so im not sure what i
botched. The hook does complete successfully as it returns non-null
value for hkb. I would appreciate any help or suggestions on where to
get help.

Thanks
