javax.jms.ConnectionFactory仅在以根用户登录时连接

Question

我以root身份在RHEL 6机器上执行以下代码，它运行完美。但是当我以较小权限的任何用户执行它时，我得到javax.naming.NamingException:连接到任何服务器失败。服务器tride: [remote://myserver::myport]。这似乎是一个权限问题，但我的程序访问的所有文件设置为777。

是什么导致了这种情况的发生?

更新显然它不解析主机名到ip地址，除非我是根。现在我使用ipaddress代替(我将使用Iputils稍后解析)。现在我得到以下错误:

您是否尝试在受限端口(如80)上托管主机?
