错误原因：找错误时应该去看错误提示Can‘t connect to X11 window server using ‘:1.0‘ as the value of the DISPLAY variable.从中我们找到了两个关键点：x11 windows server和变量DISPLAY。
问题解决：
1.通过查询我们得知，Linux默认情况下是启动x11 windows server的，而且它是与windows的图形工具显示相关；
2.变量DISPLAY的值与程序界面显示在机器的哪个图形化终端有关，通过执行who命令和who am i 命令，可以知道当前图形化终端是第n个(如下是第2个)，那么变量DISPLAY的值应该是IP:（n-1）或者：（n-1）(如下是：1.0)，只有这样java图形程序的界面才能正常显示出来。
[root@neokylin import_jre]# who root tty2 2015-02-06 13:18 root pts/1 2015-02-06 13:42(192.168.100.126) highgo pts/2 2015-02-06 13:42(:1.0) [root@neokylin import_jre]# who am i highgo pts/2 2015-02-06 13:42(:1.0) [root@neokylin import_jre]# echo $DISPLAY :1.0
如果DISPLAY的值不匹配，可以询问该机器的管理员查看机器是否正常开启，或者找其他图形终端的访问者让其关闭远程桌面访问，仅保留你的远程桌面，然后再尝试重新执行程序。
