Q: What does "... Can"t connect to X11 window server using ":0.0" as the
value of the DISPLAY variable" mean?
A: This error may occur if you run Reports and Bugzero is installed on a
linux/Unix system. The exception is thrown in Unix environments by the Java
AWT toolkit when it can"t make a connection to a X11 server. Make sure that you have
your local X11 running, and that the reported DISPLAY environment variable value
is as expected.
An alternative (recommended):
If you do not run X Windows (the case for most of the server
machines), you can
install Xvfb (X Virtual Frame Buffer).
In your launch script (such as tomcat.sh), add the following lines:
if [ -f /usr/X11R6/bin/Xvfb ]; then
/usr/X11R6/bin/Xvfb :1 -screen 0 1x1x8 > /dev/null 2>&1 &
fi
export DISPLAY=:1.0

【 在 stupidboy (三蛋——笨蛋、坏蛋、混蛋) 的大作中提到: 】
: 运行环境：Tomcat4.0.1 + RedHat7.3
: 用到了JFreechart，通过Servlet生成动态统计图。
: 如果Tomcat 是在KDE里面启动的，画图，如果在系统启动时通过rc.local启动的，
: 则不能正确画图，提示DISPLAY环境变量错误，
: (localhost_log.2002-12-29.txt)
: java.lang.InternalError: Can"t connect to X11 window server using "192.
: 168.0.2:0.0" as the value of the DISPLAY variable.
: (catalina.out)
: Xlib: connection to "192.168.0.2:0.0" refused by server^M
: Xlib: No protocol specified
