Huh... that's weird. Can you check your installation? There should have
been four lwjgl plugins installed on our system (in the plugins folder):
- org.lwjgl.doc
- org.lwjgl.source
- org.lwjgl.test
- org.lwjgl
The first two are not important, and the third is obviously installed as
it contains the test view (and you obviously see the menu entry). Is the
last one installed? Does the folder (org.lwjgl_2.2.1) contain
- lwjgl.jar
- lwjgl_util.jar
and a folder called "native" with the native libraries?
Cheers,
Jens

GEF3D does not work with Eclipse 3.6 yet, you have to use Eclispe 3.5
instead.
However, this does not explain why the lwjgl (native) library isn't
found. I would guess that it's the 64 bit causing the problems. I will
have a look at this. I figure that there may be a problem loading the 64
bit version of lwjgl. Although this would probably be my own code (which
I donated to lwjgl.org) causing this problem (I assume I'd simply
forgotten win 64 bit), I do not have access to the lwjgl update site.
Thus I cannot fix the bug, and as there is nobody at lwjgl maintaining
the update site, I'm afraid in that case this cannot be fixed. As I
wrote in the previous thread, I've planned to update to the latest lwjgl
version, and I maybe figure out a way of how to fix the problems with
the update site. Stay tuned, I will write about that either in the GEF3D
blog and/or in this newsgroup.
Cheers,
Jens

uh ok, I misinterpreted the requirement as > 3.5.

indeed. I've tried with Galileo-32 bit in the same 64 bit system and got
the same error:
java.lang.UnsatisfiedLinkError: no lwjgl in java.library.path
