Can't connect to X11 window server using ':0.0' as the value of the DISPLAY vari

第一次 error信息

 

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

 

第二次以后

 

java.lang.NoClassDefFoundError

 

在google上搜索关键字Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable

 

原因

 

没安装x-window

 

顺便, 即使安装了x-window,也可能出现这种问题

未经验证的解决方法是

 

$ export DISPLAY=127.0.0.1:0.0
$ xhost +

 

 

对策

修正内容,增加以下变量

 JAVA_OPTS=-Djava.awt.headless=true

    或者 CATALINA_OPTS='-Djava.awt.headless=true'
修正方法
   用export或者etc/profile增加环境变量
   或者修改tomcat_home/bin下边的startup.sh或者catalina.sh
JAVA_OPTS=-Djava.awt.headless=true 
echo "Using CATALINA_BASE:   $CATALINA_BASE"
echo "Using CATALINA_HOME:   $CATALINA_HOME"     
echo "Using CATALINA_TMPDIR: $CATALINA_TMPDIR"
echo "Using RUNJAVA:       $_RUNJAVA"
echo "Using JAVA_OPTS:  $JAVA_OPTS"
