I need help to start using Rabbitmq (client)

I want start using the rabbitmq client, to receive datas from a queue. This queue is online, and I have all the informations to create a connection to it:

• host


• username


• password


• virtual host


• port

I wrote an application in java to create a connection using the ConnectionFactory class:

import com.rabbitmq.client.ConnectionFactory;


public class Stats {


    public final static String TOKEN = "1234567";
    public final static String USER = "username";
    public final static String HOST = "amqp.host.org";
    public final static String VHOST = "topsecretdatas";
    public final static int PORT = 5672;


    public static void main(String[] args)
        throws java.io.IOException, java.lang.InterruptedException {

        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setHost(HOST);
        connectionFactory.setUsername(USER);
        connectionFactory.setPassword(TOKEN);
        connectionFactory.setVirtualHost(VHOST);

        connectionFactory.newConnection();
    }
}

But at the last line, an exception is raised (com.rabbitmq.client.AuthenticationFailureException). The message is:

• "ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile."

So:

1. Are there some log files on my PC? I think no..


2. I don't know how to change the authentication mechanism. How can I resolve my problems and create my connection?
