I have a problem with JOGL2.
My JOGL2Template.java compiles fine, but executing it results in the following error:
D:\java\java\jogl>javac JOGL2Template.java <== compile ok
D:\java\java\jogl>java JOGL2Template <== execute error

Here is the JOGL2Template.java source code:

Any ideas what might be the cause of these errors?
