jME demos not working via JWS

The jME demos appear to be hit and miss. Right now I can’t get any of them to work via JWS. This is on my home computer and the work one.

The home laptop is a winXP, ATI setup. The work desktop is a winXP, GeForce setup.

Are others having any issues?

What’s the most appropriate place to post/ask for help?

They used to work BTW.

I can’t get the latest .9x version of lwjgl to run either.


Dr. A>

If the latest LWJGL doesn’t work, jME won’t work for you either. It sounds like either cards that are too old or video driver issues. What are your exact cards and have you tried upgrading the drivers?

Here is some info from running glView.

Given the fact I can run lots of other openGL apps, I'm pretty sure something else is going on. The drivers should be at most a few months old. I can understand trying to do something such as using a vertex shader would fail, but just a simple cube demo app, should be fine.

There isn't any kind of clean exit from lwjgl either, just exits. At least jME says something was wrong, then exits.

Should I try messing with the lwjgl code first? I've got no experience in jni, so I could only look at the java code itself.

The demos used to works on my cpu unless I switch to lwjgl 0.93… (this version of lwjgl works very well, I use it every days)


I think the last officially supportet LWJGL Version for jME was 0.92 - does it work with 0.92 ?

Right, webstart version is LWJGL 0.92, make sure you don’t have 0.93 in your system path or something. It could be interfereing with webstart pulling down 0.92 and setting it as the active one.

OT: lwjgl .93 is officially out now so we could work on supporting that… It would fix some issues we currently have such as how opengl pauses if it loses focus and the whole windowed mode being in the upper left corner instead of centered.

The lwjgl site only shows .93 alpha. Do you have to get the sources to get .93?

Any ideas on why my card is acting goofy? I tried some jogl demos today and got them working with no issues.


Dr. A>

LWJGL 0.93 is out… Don’t read the “alpha” things, it just means that lwjgl is in alpha status (until 1.0 is out).


I was sorrta able to get the demos to work, but not by using the JWS versions.

I pulled the source from CVS and did a build. The first few demos under the jme.renderer package seemed ok.

When I tried the water simulation under effects, it put the text on the button, but that was it. Then when I hit ESC on the windowsXP laptop I was using, it blue screened then rebooted!!


Has this happened to anyone else? I ‘think’ I recall having a blue screen before when I tried to used one of the JWS demos.
