java.rmi.ConnectException：連接拒絕主機：192.168.0.55

Question

我是一個初學NetBeans和Java的人，所以我很確定我的問題是非常基本的，但試圖找到解決方案2周我完全堅持

這就是問題所在：

我想實現一個RMI服務器的客戶端應用程序 所以第一步是與NetBeans試圖讓從網上

我使用的Oracle教程有一個工作第一部分實施 http://docs.oracle.com/javase/tutorial/rmi/server.html

我的問題不在於客戶端不連接，而是服務器甚至無法註冊到我給他的端口。錯誤消息中的IP是我的私有IP。

這是錯誤消息我得到：

我運行Windows 8.1，和殘疾人防火牆。我也使用了安全文件授予的所有權限

這是我的Java代碼，我從NetBeans中執行：

import Conexion.DatosConexion; 
import Servidor.*; 

import java.rmi.RemoteException; 
import java.rmi.registry.LocateRegistry; 
import java.rmi.registry.Registry; 
import java.rmi.server.UnicastRemoteObject; 

public class ServidorPlanificadorStarter implements InterfazServidorPlanificador { 

    private static String ip; 
    private static String Servidor = "SERVIDORNUBE"; 
    private static int puerto; 
    private static String nombreServidor; 

    public ServidorPlanificadorStarter(){ 
     super(); 
    } 

    public static void main(String[] args) { 
     if (System.getSecurityManager() == null) { 
      System.setSecurityManager(new SecurityManager()); 
     } 
     try { 
      DatosConexion datos = DatosConexion.getInstance(); 

      ip = datos.getServiceIP(Servidor); 
      puerto = Integer.valueOf(datos.getServicePort(Servidor)); 
      nombreServidor = datos.getServiceName(Servidor); 

      System.setProperty("java.rmi.server.hostname", ip); 

      System.out.println("Conectando a: " + ip + "/" + puerto + "/" + nombreServidor); 

      InterfazServidorPlanificador engine = new ServidorPlanificadorStarter(); 
      InterfazServidorPlanificador stub = 
       (InterfazServidorPlanificador) UnicastRemoteObject.exportObject(engine, puerto); 
      Registry registry = LocateRegistry.getRegistry(); 
      registry.rebind(nombreServidor, stub); 
      System.out.println("ServidorPlanificador bound"); 
     } catch (Exception e) { 
      System.err.println("ServidorPlanificadorStarter exception:"); 
      e.printStackTrace(); 
     } 
    } 

} 

的界面如下（很基本的，因爲我已經做了與它無關）

public interface InterfazServidorPlanificador extends Remote { 

    //void addObserver(RemoteObserver o) throws RemoteException; 

}

您是否像在教程中一樣啓動RMI註冊表？ http://docs.oracle.com/javase/tutorial/rmi/running.html
