java errors

hey, i finally got my development environment setup and my graphics cards sorted out, and when i go to run the java host software i get this:

it really sucks because i need to run the java program to be able to test the controller boards. i need to test the controller boards in order to get them ready for production.

Looks like a graphics prob. Have you got Java3D 1.4 or 1.5?

Best wishes

at the top of the error output it says this, so i'm guessing i have java3d installed correctly:

Java 3D 1.4.0-build5-experimental 24 Jun 2005 10:18:22 PDT

unfortunately i have an ATI card. their linux support really sucks, so i'm using the open source drivers. they may be the problem. i ordered an nvidia card today that should get here on monday. hopefully that will fix the problem.

Though some Nvidia cards can have (easily fixed) problems of their own. See

I use ATI cards in my Windows PC and discovered that AoI was constantly crashing my graphics card. I eventually asked Peter Eastman what I could do and he suggested disabling OpenGL. I did that and never had another problem of that sort. You might want to try that and see if it helps at least till you get your Nvidia cards.

You need the next version up. I have:

Java 3D [dev] 1.5.0-build4-experimental 28 Jun 2006 09:13:01 PDT


This is available from:

[java3d.dev.java.net]

With release notes:

[j3d-core.dev.java.net]

If it works on the Mac, that's probably worth wikifying.

Vik :v)

okay, it says the the wrong info in the wiki... i guess i should update it.
