Tomcat start from terminal

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.

Could you help me...?

Thank you

Hi

What do you mean by "I thought that setting DISPLAY variable does not need"? Have you tried to set the DISPLAY environment variable?

Putty is an ssh client! You do not have any running graphical environment. This is reason for that error.

neothemachine had a similar concern and made it work several months ago, I don't remember how:
