但是当我尝试运行程序时，出现以下错误。

我尝试改变

-ORBInitialHost localhost 到 -ORBInitialHost 192.168.1.33

但错误仍然存​​在。任何人都可以建议我开始使用 orbd 的解决方案。

【问题讨论】：

您是否启动了“orbd”计划？

我正在使用这一行启动 orbd 程序。那是发生错误的行。 Runtime.getRuntime().exec("orbd -ORBInitialPort 1059 -port 1032 -ORBInitialHost localhost");

不，不是。查看堆栈跟踪。 Runtime.exec() 没有出现在它的任何地方。当您调用 resolve_initial_references() 时会发生这种情况。

似乎没有执行。我尝试在命令提示符下启动 orbd 并得到同样的错误。你知道为什么吗？

您从这个程序或从 orbd 得到了同样的错误？为什么要将所有这些端口指定为 orbd 而不是您自己的代码！尝试不使用所有端口参数。

【参考方案1】：

在控制台中运行 orb 你的系统 start orbd -ORBInitialPort 1050 运行 YourServer.java -ORBInitialPort 1050 -ORBInitialHost localhost 运行 YourClient.java -ORBInitialPort 1050 -ORBInitialHost localhost

谢谢。我什至忘记了我在 SO 上问过这个问题。 :D :D
