Subject RE: Off-topic - Java and X11 Window Server
Date Wed, 07 Jan 2004 18:50:51 GMT
I am not an expert on any *nix system, but faced the same problem once.

I had to set to DISPLAY varirable to :1.0 (export DISPLAY=:1.0). It is
important that this is set for the same user that is running Tomcat.

grts,

Patrick

Subject: Off-topic - Java and X11 Window Server


Hi guys,
Have anybody ever seen this error before? The X11 seems to be alive at my
environment --> Conectiva Linux. The target Java app,GraficoBig, works with
a free package, called org.jfree.char and org.jfree.gui.

500 Internal Server Error
java.lang.InternalError: Can't connect to X11 window server using ':0.0' as
the value of the DISPLAY variable.
