This sounds more like a problem with your Eclipse setup or your project code. If you already have a working JOGL project that draws a line, you should be able to import and use anything from JOGL. Are you sure you're not trying to import something that doesn't exist in JOGL? Perhaps you're looking at wrong/old documentation on the web.
