If your this works on other machines, then you should not worry about the JNLP file.

But I guess/see that the error is because Java 3D is not supported in your machine yet. Maybe because of software needed or hardware needed. I deduct that from the following line.

"Caused by: java.lang.NullPointerException: Canvas3D: null GraphicsConfiguration "

Edit: Have you tried running a sample Java 3D application on your Linux machine that works? That should help you debug this problem.
