I am trying to connect with secure websocket connection wss:// in android using org.java_websocket.client.WebSocketClient API, but unable to connect with https. However it is working fine with ws://.. Here is my code.

private void connect(String websocketEndPointUrl) throws Exception {
    URI uri;
    try {

        websocketEndPointUrl="wss://echo.websocket.org:443";
        Log.i(TAG, " WSURL: " + websocketEndPointUrl);

        uri = new URI(websocketEndPointUrl);
    } catch (URISyntaxException e) {
        Log.e(TAG, e.getMessage());
        return;
    }

    mWebSocketClient = new WebSocketClient(uri,new Draft_17()) {
        @Override
        public void onOpen(ServerHandshake serverHandshake) {
            Log.i("Websocket", "Opened");
         }

        @Override
        public void onMessage(String s) {
            //final String message =s;

         }

        @Override
        public void onClose(int i, String s, boolean b) {
            Log.i("Websocket", "Closed " + s);
         }

        @Override
        public void onError(Exception e) {
            Log.i("Websocket", "Error " + e.getMessage());
         }
    };
    mWebSocketClient.connect();
}

i am using online test websocket url: ws://echo.websocket.org (port 80) // working with that wss://echo.websocket.org (port 443) As per my observation there is no need of certificate required in my code. Can anyone suggest me what is a reason and how i can fix this.

In my case, I need two thing to fix "Trust anchor for certification path not found" error when websocket connect():

  1. HttpsURLConnection requests that particular wss host (but in https:// form) successfully at least once.
  2. Then dosetWebSocketFactory() as mentioned in accepted answer. Which this extra method (plus new Draft_17()) only appeared in library version org.java-websocket:Java-WebSocket:1.3.0, not 1.4.0.

Note that don't test with allowAllSSL() like this answer do, which affect the two thing above not working.
