I warn you…this is most likely going to be a crappy answer since I am certainly no expert. As a matter of fact, you could call me a newbie
Maybe someone will be able to chime in to clarify what I’m going to say.
Anyway…I’ll give it a shot.
The error is caused by the fact that the compiler can’t locate the necessary jogl files while trying to gather everything it needs. Being only a machine, you have to tell the blasted thing exactly where to find the jogl files it needs, and those files live in the jogl.jar you unpacked from your download. So…the short answer is you need to add the jogl.jar to your classpath.
In my IDE you go to the ‘project’ tab, ‘project settings’, ‘required libraries’, ‘new’, ‘add’, ‘path or archive’. NOW…when you click on the ‘add archive’ it puts up a file chooser dialog, and you just navigate to the folder where you have the jogl.jar stored and select it. After all this, the IDE will require you to give what you just did a name so that you can select it in the future without having to redo all this. Let’s say you name it ‘path_to_jogl.jar’. Now that name will appear in your ‘project/ project settings/ required libraries’ window. Before you try to compile the project, make sure you select that item, or it STILL won’t be able to find the files.
Then, when you try to run the program you just successfully compiled, you’ll get more errors unless you tell the IDE where to find the two .dll’s you unpacked with your download. Again, in my IDE, you go to ‘project, project settings, JDK Tools, run application, new’. Then there is a window where you can type in parameters to alter the runtime configuration. In other words, when it runs the program, it needs to know where to find the .dll’s so that it can deal with the native calls needed by your program. On my IDE I type in the following in the ‘add parameters’ window:
-Djava.library.path=C:\jogl-win32 -classpath “$[ClassPath]” $[JavaClass]
where C:\jogl-win32 is the location of both .dll’s.
OK…that’s it. As I said, perhaps others will be willing to correct me / assist you if you have more questions on this topic 
Good luck sir.
