javax.naming.ConfigurationException：PortableRemoteObject.toStub（）出现问题。未导出对象或未找到存根

Question

我正在编写Iiop服务器，尝试运行它时遇到以下错误：

从我对这个错误的了解中，我需要一个对象的强类型声明，这样垃圾收集器就不会丢弃它，因此为什么我试图添加一个仅执行此操作的函数对象，但仍然是错误在正常运行和带有断点的情况下仍然存在，该错误在ctx.rebind行触发。

public class ExecRmiIiopServ {
    public ExecRmiIiopServ(String host, String port, String nume) throws Exception {
        Runtime.getRuntime().exec("cmd /c start orbd -ORBInitialPort 1050");
        Properties props = new Properties();
        props.setProperty("java.naming.factory.initial", "com.sun.jndi.cosnaming.CNCtxFactory");
        props.setProperty("java.naming.provider.url", "iiop://" + host + ":" + port);
        ExecRmiInte functions = new ExecRmiImpl();
        Context ctx = new InitialContext(props);
        ctx.rebind(nume, functions);
        System.out.println("Java RMI IIOP waiting: " + host + ":" + port + "/" + nume);
    }
    public static void main(String args[]) throws Exception {
        if (args.length > 2)
            new ExecRmiIiopServ(args[0], args[1], args[2]);
        else
            new ExecRmiIiopServ("localhost", "1050", "ExecIiop");
    }
}

ExecRmiImpl（）类暂时是这样的：

public class ExecRmiImpl implements ExecRmiInte {
    public ExecRmiImpl() { }
}

我在做什么错了？
