我正在尝试在两台机器上运行一个简单的客户端-服务器程序，

我读了这个页面，但我得到了这个错误：

我如何使用 Corba 和 java 在互联网上的两台机器上运行像“Hello Wrold”这样的简单程序？

我认为互联网是这里的关键。您需要确保：

  1. 客户端可以通过您指定的IP 地址访问服务器（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伪装规则）；
  2. 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子网上运行时工作，然后才继续进行分布式设置。

  1. Run orb start orbd -ORBInitialPort 1050
  2. Run your class client and server with: -ORBInitialPort 1050 -ORBInitialHost localhost

or alternative: 1. Run server: tnameserv -ORBInitialPort 1050

  1. Run client: java YourServer -ORBInitialPort 1050 java YourClient -ORBInitialHost 127.0.0.1 -ORBInitialPort 1050
