CORBA通讯问题

Question

这可能太局限了，但我希望有人可以帮助我正确阐明我的问题。

因此，我们有一个前端Web服务器，该服务器使用CORBA与后端应用程序服务器进行通信。我曾被要求将后端应用程序移植到LINUX盒中。但是，为了测试它，我试图将前端Web服务器指向LINUX后端。

我们正在使用omniORB-4.1.4，这是获取后端系统实例的方法：

        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，似乎可以很好地实例化。但是，当后端在LINUX机器上运行时，它将给出Connection
Refused异常，并且主机名为127.0.0.1。

与属性有关吗？因为这两个盒子在定义的端口上可以很好地相互听到。

另外，当我在Linux机器上执行netstat时，它会显示从Solaris机器到端口的LISTENING连接。是什么使响应返回为127.0.0.1？

Solaris框称为yyyy，而Linux框称为xxxx。初始端口和主机通过ini文件获取。

Answer 1

问题与代码无关。这与连接性有关。

在LINUX框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。
