Running a Java GUI application within docker

I am unable to run a Java GUI application from within a docker environment. The error message is that "Can't connect to X11 window server using ':0' as the value of the DISPLAY variable"

I have tried setting the DISPLAY variable to :0 and to unix:0.

This is the command that I am using to start the docker container:

docker run --privileged --mount type=bind,source=$CNG_PATH,destination=/home/user/contiki-ng -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix -v /dev/bus/usb:/dev/bus/usb -ti contiker/contiki-ng

When I try to run the GUI application, I get the following error message:

run:
     [java] No protocol specified
     [java] Exception in thread "main" java.awt.AWTError: Can't connect to X11 window server using ':0' as the value of the DISPLAY variable.
