这可能太本地化了，但我希望有人能帮助我正确阐明我的问题。
因此，我们有一个使用 CORBA 与后端应用程序服务器通信的前端 Web 服务器。我被要求将后端应用程序移植到 LINUX 机器上，我做到了。但是，为了测试它，我试图将前端 Web 服务器指向 LINUX 后端。
我们使用的是omniORB-4.1.4，后台系统实例的获取方式如下:
String args[] = new String[0];
System.out.println(getDateTime()+"Instance: Connecting to: "+initialHost+" "+initialPort+" "+enviornment+" "+version);
java.util.Properties props = new java.util.Properties();
props.put("org.omg.CORBA.ORBInitialPort", initialPort);
props.put("org.omg.CORBA.ORBInitialHost", initialHost);
props.put("com.sun.CORBA.giop.ORBGIOPVersion", "1.0");
orb=org.omg.CORBA.ORB.init(args,props);
当前端和后端都在 SUN/Solaris 机器上运行时，它似乎可以正常运行实例。但是，当后端在 LINUX 机器上运行时，它给出了 Connection Refused 异常，主机名为 127.0.0.1

跟属性有关系吗？因为这两个盒子在定义的端口上可以很好地相互听到。
此外，当我在 Linux 机器上执行 netstat 时，它会显示一个从 Solaris 机器到端口的监听连接。是什么让响应返回 127.0.0.1？
Solaris box 称为 yyyy，Linux box 称为 xxxx。初始端口和主机通过 ini 文件获取。
最佳答案
问题与代码无关。这与连通性有关。
在 LINUX 机器 cmrheldv 上，我必须编辑/etc/hosts 文件并将 127.0.0.1 更改为本地主机的真实 IP。
