Jgol error with JNLP Applet Launcher

Question

I've been able to deploy my applet with the JNLP launcher and jogl, but whenever I try to use an animator in my program applet crashes with this error. Am I forgetting to add something in the code? Any help is appreciated.
java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/jogamp/opengl/util/Animator
     at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source)
     at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)

and other stuff.

running JaNeLA gives me this error.
cvc-complex-type.2.4.a: Invalid content was found starting with element 'extension'. One of '{property, package}' is expected.
The help here http://pscode.org/janela/help.html really didn't help too much.
The help for that error states:
This one fools a lot of people. It most often means that elements are out of the correct order in the launch file. Check the spelling, then try shifting the element further up the document. Did you check the file against the documentation for creating JNLP files? Did you try reordering the elements? Did you check the spelling of the element name?
Note that those type of errors are produced by the J2SE based XML APIs when validating an XML document against an XSD. That means that there should be thousands of hits across the internet that discuss that error.
Any other ideas?Some:
- Do not expect the people here to spoon feed answers to you.
- Describe what actual methods you used to try and resolve the error, rather than just state the tools are 'not that helpful'.
- Mention whether the JNLP can be launched as a free floating app., like I suggested you try. After all, we are not psychic.
It might be obvious that I am a little irritated by your reply. JaNeLA was primarily written by me, though it has significant contributions from another developer. It was written for the purpose of helping people to validate JNLP files and resources, but the user must be able to think for themselves & do some research, in order to get good use from it.
When I initially saw the thread to do with a problem in regard to the JNLP applet launcher, I was about to pass it by completely. These forums are not for providing support for 3rd party APIs. But since the JNLP was obviously wrong I decided to give you some help on that, in the hope that would solve the problems.
If it doesn't solve the problem, or if you continue with this 'helpless lamb' attitude, I will be opting out of the thread.
