java - 调用 "lookup"后，本地网络上的 RMI 出现 NotBoundException-Exception

Question

我在 RMI 上遇到问题:

我的RMI客户端尝试获取192.168.1.37的注册表

Registry registry = LocateRegistry.getRegistry("192.168.1.37",1099);
String[] s = registry.list();
    for( String obj : s ) {
        System.out.println("  " + obj);
    }
IMaster master = (IMaster) registry.lookup ("rmi://192.168.1.37:1099/Master");

我的 RMI 服务器如下所示:

Registry registry = LocateRegistry.getRegistry();
IMaster m = new Master(3, 3);
registry.rebind ("Master", m);
System.out.println ("Master Server is ready.");

registry-List [String[] s =registry.list();] 知道“Master”绑定(bind)。这意味着:网络没有问题并且注册表存在。该对象也已导出。 (我使用 RMI 的 eclipse 插件)。

但是在客户端的查找行中我遇到了异常:

有人知道如何解决这个问题吗？ :)谢谢

尝试改变

IMaster master = (IMaster) registry.lookup ("rmi://192.168.1.37:1099/Master");

至

IMaster master = (IMaster) registry.lookup ("Master");
