Exception in thread “main”

I tried to run it under IntelliJIdea4.5, Win2000, jdk 1.4.2

You have to add “vecmath.jar” to your classpath.

You can find it in the Xith3D archive, in the “third-party” directory.

vecmath.jar is added to project library, all used libs are added too. Paths are defined in sistem environment variables. If I try to run demos from …/xith3d/demo/, (they use runtest.bat to fix paths), nothing changes. Appears java.lang.NoClassDefFoundError for different classes.

try to run it with jdk 1.5

have you read: http://xith.org/Installing ?

Have you tried the troubleshooting suggestions?

Will.
