Just to clarify a bit... I've trying to use org.eclipse.swt.opengl.GLCanvas which is why I'm using createExternalGLContext().  It works fine and I can draw using GL 2.1 functions.

I just realized there is a com.jogamp.opengl.swt.GLCanvas but I can't seem to get it to work at all.  Calling getGL() always returns null.  toString() on the canvas gives me:

Req Profile: GLProfile[GL3/GL3.hw]
SWT-GLCanvas[Realized false,
        null-drawable,
        Factory   null,
        handle    0x0,
        Drawable size -1x-1,
        SWT size 320x299]

Is there a complete example using com.jogamp.opengl.swt.GLCanvas anywhere that I can try?
