You could try this ancient thread:
http://lwjgl.org/forum/index.php/topic,917.0.htmlOr implement the desired model format on your own. Most 3d model libs i know have been written in c/c++. Though you could write a wrapper or do the hard work on your own. But a full fledged lib for lwjgl is afaik not available.
On the other way you might be happy with the jMonkeyEngine. They use lwjgl too and have some 3d model import stuff
