CORBA，在两台机器上

我想在两台机器上运行一个简单的客户端 - 服务器程序运行的Hello World，CORBA，在两台机器上

我读这page但我得到这个错误：

你可以请让我知道如何在两台使用Corba和java的互联网上运行一个简单的程序，例如“Hello Wrold”？

问候。

有你检查的防火墙？当你运行'java HelloServer -ORBInitialPort 1050'检查'netstat -na'（检查windows语法）如果服务器在1050上监听。然后运行客户端。 –

我检查过它。 sever正在监听端口1050. – Blueferi

我如何在两台机器上使用Corba和java在互联网上运行一个简单的程序，例如“Hello Wrold”？

我认为在互联网上是关键。你需要确保：

服务器对IP地址的客户端访问指定（即，或者IP地址是公共的，或者有设立任何相关的防火墙适当masquarading规则） ;
有合适的防火墙和/或端口转发规则，允许客户端访问服务器上的端口1050。

我会建议首先让客户端和服务器在同一子网上运行时工作，然后才转移到分布式安装。

您的意思是我在同一台机器上运行服务器和客户端吗？我在一台机器上运行了该程序，它工作正常。 – Blueferi

请帮忙... – Blueferi

运行ORB start orbd -ORBInitialPort 1050
运行你的类的客户端和服务器：-ORBInitialPort 1050 -ORBInitialHost localhost

或替代： 1.运行服务器： tnameserv -ORBInitialPort 1050

运行客户端： java YourServer -ORBInitialPort 1050 java YourClient -ORBInitialHost 127.0.0.1 -ORBInit ialPort 1050
