LWJGL update

Hi there.
I would like to update the LWJGL library in the SDK to the latest (2.9) version. I’ve tried replacing the .jar file but I can’t find the location of the native part.
Also I’ve updated the SKD but no luck. Does any one know what I should do? Thanks in advance.

Found a solution: I’ve downloaded the natives from there and replaced them https://code.google.com/p/jmonkeyengine/source/browse/trunk/engine/lib/?r=10572#lib%2Flwjgl .
Hope it helps someone.
