Question

我正在使用Putty连接到远程运行的服务器。为监控服务器，我在putty终端下输入了jconsole

我得到的是以下异常。

[user001@test.hhh.com ~]$  jconsole
Exception in thread "AWT-EventQueue-0" java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.

即使我尝试更改网站后面的Putty设置。

Getting a HeadlessException: No X11 DISPLAY variable was set

但我一次又一次得到同样的例外情况，请你告诉我如何解决这个问题？

Answer 1

在本地计算机上安装X服务器，并启用其他问题中给出的X转发。

Putty：没有设置X11 DISPLAY变量，但是该程序执行了需要它的操作
