Question

我试图在两台机器上运行一个简单的客户端 - 服务器程序，

我读了这个page，但我得到了这个错误：

能告诉我如何运行像＃34;这样的简单程序。你好Wrold＆＃34;在两台使用Corba和java的机器上？

问候。

Answer 1

如何使用Corba和java在两台机器上运行像“Hello Wrold”这样的简单程序？

我认为通过互联网是关键。你需要确保：

客户端可以在您指定的 IP地址上访问服务器（即IP地址是公共的，或者在任何相关防火墙上设置了适当的masquarading规则）;
有适当的防火墙和/或端口转发规则，允许客户端访问服务器上的端口1050 。

我建议首先让客户端和服务器在同一个子网上运行时工作，然后继续进行分布式设置。

Answer 2

运行orb start orbd -ORBInitialPort 1050
使用以下代码运行您的类客户端和服务器：-ORBInitialPort 1050 -ORBInitialHost localhost

或替代方案： 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 -ORBInitialPort 1050
