는 RMI SSL을 통해 :</p> <p>인터페이스 : 핸드 셰이크 실패

Question

안녕 난 그냥 SSL로 시작 그리고 난 아주 간단한 예를 만들고 싶어, 여기에 코드입니다.

package tpfinal; 

import java.rmi.Remote; 
import java.rmi.RemoteException; 

public interface CentralTimeService extends Remote { 

    int PORT = 8844; 

    long getTime() throws RemoteException; 

} 

클라이언트 :

package tpfinal; 

import java.rmi.AccessException; 
import java.rmi.NotBoundException; 
import java.rmi.RemoteException; 
import java.rmi.registry.LocateRegistry; 
import java.rmi.registry.Registry; 
import java.text.SimpleDateFormat; 
import java.util.Date; 

import javax.rmi.ssl.SslRMIClientSocketFactory; 

public class CentralTimeServiceClient { 

public static void main(String[] args) { 
try { 
      System.setProperty("javax.net.ssl.keyStore","C:\\Users\\luciano\\workspace\\Distribuida\\bin\\keystore"); 
       System.setProperty("javax.net.ssl.keyStorePassword","123456"); 
       System.setProperty("javax.net.ssl.trustStore","C:\\Users\\luciano\\workspace\\Distribuida\\bin\\truststore"); 
       System.setProperty("javax.net.ssl.trustStorePassword","123456"); 
       Registry registry = LocateRegistry.getRegistry(null, CentralTimeService.PORT, new SslRMIClientSocketFactory()); 
       CentralTimeService cts = (CentralTimeService) registry.lookup("CentralTimeService"); 
       //Invocamos llamada RMI 

long serverTime = cts.getTime(); 
System.out.println(serverTime); 

System.out.println("Central server time is: " + SimpleDateFormat.getDateInstance().format(new Date(serverTime))); 

} catch (AccessException e) { 
e.printStackTrace(); 
} catch (RemoteException e) { 
e.printStackTrace(); 
} catch (NotBoundException e) { 
e.printStackTrace(); 
} 

     } 

    } 

서버 :

패키지 tpfinal;

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

import javax.rmi.ssl.SslRMIClientSocketFactory; 
import javax.rmi.ssl.SslRMIServerSocketFactory; 

public class CentralTimeServiceImpl extends UnicastRemoteObject implements CentralTimeService { 

    protected CentralTimeServiceImpl() throws RemoteException{ 
     super(0, new SslRMIClientSocketFactory(), new SslRMIServerSocketFactory(null, null, true)); 
     System.setProperty("javax.net.ssl.keyStore","C:\\Users\\luciano\\workspace\\Distribuida\\bin\\keystore"); 
     System.setProperty("javax.net.ssl.keyStorePassword","123456"); 
     System.setProperty("javax.net.ssl.trustStore","C:\\Users\\luciano\\workspace\\Distribuida\\bin\\truststore"); 
     System.setProperty("javax.net.ssl.trustStorePassword","123456"); 
    } 

    @Override 
    public long getTime() throws RemoteException { 
     return System.currentTimeMillis(); 
    } 

    public static void main(String[] args) { 
     try { 
      Registry registry = LocateRegistry.getRegistry(null, CentralTimeService.PORT, new SslRMIClientSocketFactory()); 
      CentralTimeServiceImpl ctsi = new CentralTimeServiceImpl(); 
      registry.bind("CentralTimeService", ctsi); 

      System.out.println("Central time service bound in registry"); 
     } catch (Exception e) { 
      System.out.println("Central time error: " + e.getMessage()); 
      e.printStackTrace(); 
     } 

    } 



} 

그리고 마지막으로 rmiregistry에

:

package tpfinal; 

import java.rmi.registry.LocateRegistry; 

import javax.rmi.ssl.SslRMIClientSocketFactory; 
import javax.rmi.ssl.SslRMIServerSocketFactory; 

public class RmiRegistry { 

    public static void main(String[] args) throws Exception { 
     LocateRegistry.createRegistry(CentralTimeService.PORT,new SslRMIClientSocketFactory(), new SslRMIServerSocketFactory(null, null, true)); 
     System.out.println("Rmi Registry running on port " + CentralTimeService.PORT); 
     System.setProperty("javax.net.ssl.keyStore","C:\\Users\\luciano\\workspace\\Distribuida\\bin\\keystore"); 
     System.setProperty("javax.net.ssl.keyStorePassword","123456"); 
     System.setProperty("javax.net.ssl.trustStore","C:\\Users\\luciano\\workspace\\Distribuida\\bin\\truststore"); 
     System.setProperty("javax.net.ssl.trustStorePassword","123456"); 
     //Sleep 
     Thread.sleep(Long.MAX_VALUE); 
    } 

} 

내가 레지스트리가 잘 작동 실행하지만 서버를 실행할 때 날이 오류를주고 내가 이유를 알아낼 수 없습니다.

감사합니다. 사전에 감사드립니다.

Answer 1

1. 당신은 Registry를 작성하기 전에 그들을 실행되도록 레지스트리 클래스의 모든 System.setProperty() 통화를 이동해야합니다.

2. 서버의 System.setProperty() 호출을 모두 main() 메서드로 옮기고 Registry 개체를 가져 오기 전에 실행해야합니다.
