Alfresco 5.1 Javascript debugger error no x11 display variable was set but this program performed an operation which requires
我已经在 Ubuntu 14.04 上安装了 Alfresco 5.1，我还安装了 Javascript 脚本编辑库。然而，我的挑战是当我想通过 http://localhost:8080/alfresco/s/api/javascript/debugger 启用 javascript 调试器时，我收到以下错误：
The Web Script /alfresco/s/api/javascript/debugger has responded with
a status of 500 - Internal Error.
500 Description: An error inside the HTTP server which prevented it
from fulfilling the request. Message: 05230000 Wrapped Exception
(with status template): No X11 DISPLAY variable was set, but this
program performed an operation which requires it.
Exception: java.awt.HeadlessException - No X11 DISPLAY variable was set, but this program performed an operation which requires it.
请帮忙！！
此外，根据我的经验 - 我现在无法找到任何官方信息 - 当 Alfresco 作为服务运行时调试将不起作用。
