Question

我更倾向于使这个SSL连接正常工作，但是如果有人能告诉我为什么我的applet触发'sslv3警报证书未知'错误会很好。我通过运行“openssl s_server”和（尝试）发现了这个错误使用我的Java客户端连接到它。我将包含该程序的源代码。我听说它可能缺少一个信任存储但我创建了一个并没有帮助。

public class first extends JApplet  {

    PrintWriter toServer = null;
    BufferedReader fromServer = null;

    public void init() {

        System.setProperty("javax.net.ssl.keyStore", "javakeys");
        System.setProperty("javax.net.ssl.keyStorePassword", "javakeys");
        System.setProperty("javax.net.ssl.trustStore", "truststore.ts"); 
        System.setProperty("javax.net.ssl.trustStorePassword", "javakeys"); 

try {

        SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
        SSLSocket sslsocket = (SSLSocket) sslsocketfactory.createSocket("localhost", 4000);

        toServer = new PrintWriter(sslsocket.getOutputStream(), true);

        toServer.println("Flystar\n\r");

        InputStreamReader isr = new InputStreamReader(sslsocket.getInputStream());
        fromServer = new BufferedReader(isr, 1);

        JOptionPane.showMessageDialog( null, fromServer );


    } catch (Exception exception) {
            exception.printStackTrace();
    }

//      toServer.println("Flystar".getBytes());

    }

    public void paint(Graphics g) {

        g.setColor( Color.red );
        g.drawString("Welcome to Java!!", 50, 60 );
    }


}

谢谢， -Roland

“sslv3 alert certificate unknown”表示服务器的证书采用Java客户端无法理解的格式。
