Hi,

My develop environment is
tomcat at linux on IDC.
connect with terminal (putty).
calling GLPorfile.getDefault() makes following error.

  Actually As I use only offscreen drawable.
        drawable = GLDrawableFactory.getFactory(glProfile)
                                        .createOffscreenAutoDrawable(GLProfile.getDefaultDevice(),
                                                        glCap, null, width, height);

So, I thought that setting DISPLAY variable does not need.
