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

Any ideas what might be the cause of these errors?
