这可能太本地化了，但我希望有人能够帮助我正确表达我的问题。CORBA通讯问题
因此，我们有一个前端Web服务器，它使用CORBA与后端应用程序服务器进行通信。我被要求将后端应用程序移植到LINUX框，我也这样做了。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omniORB-4.1.4，这里是如何获得后端系统的实例：
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);
在前端和后端两种，并在Sun/Solaris系统上运行，它似乎得到了一个很好的例子。但是，当后端在Linux机器上运行，它提供了连接被拒绝的异常，以及主机名127.0.0.1

有什么事情做的属性？因为这两个盒子可以在定义的端口上完美地听到对方的声音。
此外，当我在Linux机器上执行netstat时，它显示出从Solaris机箱到端口的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。初始端口和主机是通过ini文件获取的。
所以，你不显示你在哪里得到 'initialHost'， 'initialPort'，等你用填充连接属性。那是你看到localhost地址的地方吗？您发布的错误消息显示了'cmap03'的主机名。所以，我很困惑。可以提供更多细节？顺便说一下，除了将它们作为映射传递给init方法之外，您可能还有一些运气将初始连接参数设置为Java系统变量。 – GreyBeardedGeek
@GreyBeardedGeek重申你的最后一点，我不明白为什么这会有所帮助。搜索顺序在org.omg.CORBA.ORB的Javadoc中定义，它包含系统属性和ORB初始属性。 – EJP
@EJP - 不确定是否有omniOrb，但我已经看到了解决此问题的其他情况。简单的尝试 - 如果它不起作用，没有太多时间投入尝试。 – GreyBeardedGeek
