When running programs using Graph2D
on systems without an X server, the programs crash with the following error message:
"X connection to ***.***.***.*** broken (explicit kill or server shutdown).".
on systems without an X server, the programs crash with the following error message:"X connection to ***.***.***.*** broken (explicit kill or server shutdown).".
This problem happens due to the fact that Graph2D normally communicates for several reasons (like getting font metrics) with the X server running on your system. If your program is executed on systems without an X server, e.g. on a server machine, this will lead to a program crash.
To avoid this problem, just tell your Java Virtual Machine to run without X server.
This is done as follows:
