【问题描述】：
这可能过于本地化，但我希望有人能帮助我正确地表达我的问题。
因此，我们有一个前端 Web 服务器，它使用 CORBA 与后端应用服务器通信。我被要求将后端应用程序移植到 LINUX 机器上，我照做了。但是，为了测试它，我试图将前端 Web 服务器指向 LINUX 后端。
我们使用的是omniORB-4.1.4，下面是后端系统实例的获取方式：
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，它似乎可以得到一个实例。但是，当后端在 LINUX 机器上运行时，它会给出一个 Connection Refused 异常，并且主机名为 127.0.0.1

这和属性有关吗？因为这两个盒子可以在定义的端口上很好地相互听到。
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。是什么让响应返回 127.0.0.1？
Solaris 机器称为 yyyy，Linux 机器称为 xxxx。初始端口和主机是通过ini文件获取的。
【问题讨论】：

因此，您不会显示用于填充连接属性的“initialHost”、“initialPort”等的获取位置。那是您看到本地主机地址的地方吗？您发布的错误消息显示主机名“cmap03”。所以，我很困惑。可以提供更多细节吗？顺便说一句，除了将初始连接参数作为映射传递给 init 方法之外，您还可以将初始连接参数设置为 Java 系统变量。
-
@GreyBeardedGeek 关于你的最后一点，我不明白为什么会有帮助。搜索顺序在 org.omg.CORBA.ORB 的 Javadoc 中定义，它包括系统属性和 ORB 初始属性。
-
@EJP - 不确定omniOrb，但我见过其他解决问题的情况。尝试简单的事情 - 如果它不起作用，则不会花费太多时间来尝试它。
-
@roymustang86 我怀疑在其他地方你有一个使用 'localhost' 而不是新主机名的 COSNaming 或可能的 JNDI 查找。
-
所以，我更新了错误信息。当它试图获得与 cmrheldv 的连接时，它得到一个连接被拒绝的异常，返回地址是 127.0.0.1
