CORBA，在兩臺機器上

我想在兩臺機器上運行一個簡單的客戶端 - 服務器程序運行的Hello World，CORBA，在兩臺機器上

我讀這page但我得到這個錯誤：

你可以請讓我知道如何在兩臺使用Corba和java的互聯網上運行一個簡單的程序，例如「Hello Wrold」？

問候。

有你檢查的防火牆？當你運行'java HelloServer -ORBInitialPort 1050'檢查'netstat -na'（檢查windows語法）如果服務器在1050上監聽。然後運行客戶端。 –

我檢查過它。 sever正在監聽端口1050. – Blueferi

我如何在兩臺機器上使用Corba和java在互聯網上運行一個簡單的程序，例如「Hello Wrold」？

我認爲在互聯網上是關鍵。你需要確保：

服務器對IP地址的客戶端訪問指定（即，或者IP地址是公共的，或者有設立任何相關的防火牆適當masquarading規則） ;
有合適的防火牆和/或端口轉發規則，允許客戶端訪問服務器上的端口1050。

我會建議首先讓客戶端和服務器在同一子網上運行時工作，然後才轉移到分佈式安裝。

您的意思是我在同一臺機器上運行服務器和客戶端嗎？我在一臺機器上運行了該程序，它工作正常。 – Blueferi

請幫忙... – Blueferi

運行ORB start orbd -ORBInitialPort 1050
運行你的類的客戶端和服務器：-ORBInitialPort 1050 -ORBInitialHost localhost

或替代： 1.運行服務器： tnameserv -ORBInitialPort 1050

運行客戶端： java YourServer -ORBInitialPort 1050 java YourClient -ORBInitialHost 127.0.0.1 -ORBInit ialPort 1050
