Connecting to a secured websocket

Question

I\'m trying to connect to a secured websocket using Jetty (or any other library).

The issue is I get a \"No trusted certificate found\" error. I\'m using a self-sign

Answer 1

Well, I tried using your code to replicate the problem with no avail ( get the certificate, import it with keytool command and then run the code ). my output is like this.

So i guess if you want a running web socket client in java, I guess you could just accept all certificate like the link that @tinker has gave to you.

The code should be like this. maybe you could try it and see what happen in your place.

import java.net.URI;
import java.security.cert.X509Certificate;
import java.util.concurrent.Future;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import org.eclipse.jetty.util.ssl.SslContextFactory;
import org.eclipse.jetty.websocket.api.Session;
import org.eclipse.jetty.websocket.api.WebSocketAdapter;
import org.eclipse.jetty.websocket.client.WebSocketClient;

public class Main extends WebSocketAdapter {

    public static void main(String[] args) {
    String url = "wss://qa.sockets.stackexchange.com/"; // or
                            // "wss://echo.websocket.org"
SslContextFactory sslContextFactory = new SslContextFactory();
TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
    return new X509Certificate[0];
    }

    public void checkClientTrusted(
        java.security.cert.X509Certificate[] certs, String authType) {
    }

    public void checkServerTrusted(
        java.security.cert.X509Certificate[] certs, String authType) {
    }
} };
try {
    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, new java.security.SecureRandom());
    sslContextFactory.setSslContext(sc);
    WebSocketClient client = new WebSocketClient(sslContextFactory);

    client.start();
    Future fut = client.connect(new Main(), URI.create(url));
    Session session = fut.get();
    session.getRemote().sendString("Hello");
    session.getRemote().sendString("155-questions-active");
} catch (Throwable t) {
    t.printStackTrace(System.err);
}
}

@Override
public void onWebSocketConnect(Session sess) {
super.onWebSocketConnect(sess);
System.out.println("Socket Connected: " + sess);
}

@Override
public void onWebSocketText(String message) {
super.onWebSocketText(message);
System.out.println("Received TEXT message: " + message);
}

@Override
public void onWebSocketClose(int statusCode, String reason) {
super.onWebSocketClose(statusCode, reason);
System.out.println("Socket Closed: [" + statusCode + "] " + reason);
}

@Override
public void onWebSocketError(Throwable cause) {
super.onWebSocketError(cause);
cause.printStackTrace(System.err);
}
}
