I resolved the issue of "*Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using ':0' as the value of the DISPLAY variable."*. The problem was if the "ant tar" is being issued from root whereas the owner of the X Display Socket belongs to different user then, the error pops up. So to avoid this execute "*xhost +local:all*" in the terminal of the user who owns the X Display socket and then try issuing ant from root. It works fine. This does have some security concerns but this is the easiest workaround
