I am trying to run my java app on ubuntu server, but i constantly receive this error: java.lang.InternalError: Can't connect to X11 window server. I set the DISPLAY variable to :0.0 but that didn't help. In the X11 log file i got these error messages: (EE) open /dev/fb0: No such file or directory (EE) intel(0): No kernel modesetting driver detected. (EE) Screen(s) found, but none have a usable configuration.

Use

java -Djava.awt.headless=true …

to start without connecting to the X server. This (and other tips) are found in
