Question

我在RHEL 6框上以root身份执行以下代码，它运行完美。但是当我执行它作为任何权限较小的用户时，我得到一个javax.naming.NamingException：无法连接到任何服务器。服务器tride：[remote：// myserver :: myport]。这似乎是一个权限问题，但我将我的程序访问的所有文件设置为777。

可能导致这种情况发生的原因是什么？

显然更新它不会将主机名解析为ip地址，除非我是root用户。现在我正在使用ipaddress（我将使用Iputils稍后解决）。现在我遇到了以下错误：

您是否尝试托管受限制的端口，例如80？

javax.jms.ConnectionFactory仅在登录root时连接
