java - RMI程序重新绑定(bind)错误

Question

我的代码似乎有一个大问题。我明白了:

java.rmi.ConnectException: Connection refused to host: 5.12.78.59; nested exception is: 
    java.net.ConnectException: Connection refused: connect

下面的代码:

public class Server {
  public static void main(String[] args) throws Exception {

    Generator Ob = new Generator();
    System.out.println("1");
    Naming.rebind("rmi:///Ob",Ob);

    System.out.println("Serverul s-a legat la" +
                       " registrul RMI");
  }
}

生成器定义正确，但当我执行 Naming.rebind 时，一切都崩溃了，为什么？感谢您的帮助。

当您进行重新绑定(bind)时，注册表未运行。我知道你上面的评论说了什么，但证据是不容置疑的。
