我正在使用CORBA开发一个简单的远程管理工具。这是我的服务器代码。

    }
}

但是，当我尝试运行程序时，出现以下错误。

我尝试改变

-ORBInitialHost localhost 至 -ORBInitialHost 192.168.1.33

但是错误仍然存​​在。谁能建议我一个开始orbd的解决方案。

Answer 1

1. 在控制台中运行orb，然后系统启动orbd -ORBInitialPort 1050
2. 运行YourServer.java -ORBInitialPort 1050 -ORBInitialHost localhost
3. 运行YourClient.java -ORBInitialPort 1050 -ORBInitialHost本地主机
