JFreeChart on Linux without Window Manager

Windwalker · Post by **Windwalker** » Wed Nov 12, 2008 7:41 am

Hi there,

I have a long running simulation that at the end shall create some charts.
It's running on my local machine, but when I start it on the powerful linux server, it doesn't work, since there is no window manager.

Is there a possibility to export PNGs with JFreeChart without a window manager?

Thanks for your help!

I doubt that the problem is a missing window manager. It's more likely that you have no X-server and no DISPLAY variable set. Are you able to start other X11/Java applications?

However, this question is not related to JFreeChart and you should probably ask on some X11/Linux/whatever mailinglist or forum.

hth,

... or read the FAQ, the well known always repeated yet still never read item 11. Activate the headless mode.

Or simply study the README file of your JDK.
