    <p>I have been running the hello world RabbitMQ example with the code below:</p> <pre><code>import com.rabbitmq.client.ConnectionFactory; import com.rabbitmq.client.Connection; import com.rabbitmq.client.Channel; public class Send { private final static String QUEUE_NAME = "hello"; public static void main(String[] argv) throws java.io.IOException { 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()); System.out.println(" [x] Sent '" + message + "'"); channel.close(); connection.close(); } } </code></pre> <p>and:</p> <pre><code>import com.rabbitmq.client.ConnectionFactory; import com.rabbitmq.client.Connection; import com.rabbitmq.client.Channel; import com.rabbitmq.client.QueueingConsumer; public class Recv { private final static String QUEUE_NAME = "hello"; public static void main(String[] argv) throws java.io.IOException, java.lang.InterruptedException { ConnectionFactory factory = new ConnectionFactory(); factory.setHost("localhost"); Connection connection = factory.newConnection(); Channel channel = connection.createChannel(); channel.queueDeclare(QUEUE_NAME, false, false, false, null); System.out.println(" [*] Waiting for messages. To exit press CTRL+C"); QueueingConsumer consumer = new QueueingConsumer(channel); channel.basicConsume(QUEUE_NAME, true, consumer); while (true) { QueueingConsumer.Delivery delivery = consumer.nextDelivery(); String message = new String(delivery.getBody()); System.out.println(" [x] Received '" + message + "'"); } } } </code></pre> <p>When I run the receiver it listens to the queue, and the sender says its sending the message but doesn't seem to close. I then run:</p> <pre><code>rabbitmqctl list_queues </code></pre> <p>The queue is definitely being created.</p> <p>However when I run:</p> <pre><code>rabbitmqctl list_connections </code></pre> <p>I get the following output </p> <pre><code>benuni@DeShawn:~$ sudo rabbitmqctl list_connections ls: cannot access /etc/rabbitmq/rabbitmq.conf.d: No such file or directory Listing connections ... guest 127.0.0.1 64700 blocked guest 127.0.0.1 64709 blocked guest 127.0.0.1 64614 blocked guest 127.0.0.1 64716 blocked guest 127.0.0.1 64717 blocked guest 127.0.0.1 64701 blocked guest 127.0.0.1 64699 blocking guest 127.0.0.1 64613 blocking guest 127.0.0.1 64708 blocking guest 127.0.0.1 64718 blocked guest 127.0.0.1 64706 blocked ...done. </code></pre> <p>SO for some reason the rabbitmq server is blocking my connections? Does anyone know what i need to do? Thanks, Ben</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
