jsf应用程序在jboss上抛出java.awt.headlessexception

Question

我在Windows上创建了jsf应用程序，它工作正常。 我将工作环境更改为linux。 现在我在我的应用程序上单击了文件上传控件（丰富的面孔），它引发了应用程序错误

java.awt.headlessexception。

请帮我。 我是linux新手。

提前致谢

Answer 1

需要两个步骤：

1. 启用X11转发：使用Putty，创建启用以下设置的新会话Connection > SSH > X11选中复选框X11 forwarding 。

2. 安装一些XServer：安装XMing Server并在会话期间保持运行。

GUI将通过XMing隧道传输

Answer 2

您可以再发布一些堆栈跟踪信息吗？ 是下一行：

没有设置X11 DISPLAY变量，但是该程序执行了需要它的操作。

如果是这样，请尝试将-Djava.awt.headless=true添加到您的JAVA_OPTS中，然后重新启动您的应用服务器。
