I'm beginning work on the GUI for Fyrestone, and I wanted to take a quick look at a tutorial. I checked the Wiki for FengGUI, which it seems is the best option for my game, and I downloaded FengJMEInputHandler and FengJME.
The FengJMEInputHandler doesn't compile because it can't find the correct jar to import for this:
import org.lwjgl.input.Keyboard;
There are two version of the FengJMEInputHandler in the wiki.
The new one should be for the current svn version of FengGUI.
Did you download the jar from sourceforge?
But in eclipse, you can remove all imports, and press ctrl+alt shift+o and it will find hopefully the correct imports.
Yes, I downloaded the FengGUI.jar from Sourceforge, the one linked from FengGUI's homepage. The second example of source-code has more errors than the first!
The only error I'm having doesn't seem to be with FengGUI, but with the lwjgl having an import for keyboard…

ah, did you add the lwjgl.jar libary to your project?
Since the FengJMEInputHandler class uses lwjgl directly, you need to add the lwjgl libray, only jme is not enough.
Wow. Weird. I thought that lwjgl.jar was packaged into my jme-compile. Perhaps not. Thanks!
