ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN
<p>I have installed "erlang" and "rabbitmq" in my windows 7 machine. But when I am trying to run this code I am getting One exception.</p>

 

<pre><code>package com.rabbitmq;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
public class SendMessage {
  private final static String QUEUE_NAME = "hello";
  public static void main(String[] argv) throws Exception { 
    ConnectionFactory factory = new ConnectionFactory();
    factory.setHost("localhost");
    Connection connection = factory.newConnection();
    Channel channel = connection.createChannel();
    channel.queueDeclare(QUEUE_NAME, false, false, false, null);
    String message = "Hello World!";
    channel.basicPublish("", QUEUE_NAME, null, message.getBytes("UTF-8"));
    System.out.println(" [x] Sent '" + message + "'");
    channel.close();
    connection.close();
  }
}
</code></pre>

<p>I am getting this Exception.</p>
