這可能太本地化了，但我希望有人能夠幫助我正確表達我的問題。CORBA通訊問題
因此，我們有一個前端Web服務器，它使用CORBA與後端應用程序服務器進行通信。我被要求將後端應用程序移植到LINUX框，我也這樣做了。但是，爲了測試它，我試圖將前端Web服務器指向LINUX後端。
我們使用omniORB-4.1.4，這裏是如何獲得後端系統的實例：
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);
在前端和後端兩種，並在Sun/Solaris系統上運行，它似乎得到了一個很好的例子。但是，當後端在Linux機器上運行，它提供了連接被拒絕的異常，以及主機名127.0.0.1

有什麼事情做的屬性？因爲這兩個盒子可以在定義的端口上完美地聽到對方的聲音。
此外，當我在Linux機器上執行netstat時，它顯示出從Solaris機箱到端口的LISTENING連接。是什麼使響應返回爲127.0.0.1？
Solaris框稱爲yyyy，而Linux框稱爲xxxx。初始端口和主機是通過ini文件獲取的。
所以，你不顯示你在哪裏得到 'initialHost'， 'initialPort'，等你用填充連接屬性。那是你看到localhost地址的地方嗎？您發佈的錯誤消息顯示了'cmap03'的主機名。所以，我很困惑。可以提供更多細節？順便說一下，除了將它們作爲映射傳遞給init方法之外，您可能還有一些運氣將初始連接參數設置爲Java系統變量。 – GreyBeardedGeek
@GreyBeardedGeek重申你的最後一點，我不明白爲什麼這會有所幫助。搜索順序在org.omg.CORBA.ORB的Javadoc中定義，它包含系統屬性和ORB初始屬性。 – EJP
@EJP - 不確定是否有omniOrb，但我已經看到了解決此問題的其他情況。簡單的嘗試 - 如果它不起作用，沒有太多時間投入嘗試。 – GreyBeardedGeek
