The XServer is down or not configured... normally, servers don't start X (to cut down expensive resources), but you will easily overcome this error adding the following to your application servers configuration:

"-Djava.awt.headless=true"

It is a common java vm option.

Thank you very much.

Now it presents my page, and I can see that it load all data.

But, the graphics appears like a white box, that is, when I pass the mouse over this box, I can see a link inside (eg, a pie chart with link), but the graphic is not shown.

Do you have some suggestion?

Thanks a lot.

Razer.
