Cannot browse or consume messages (with ttl setting) from a Queue.

[swapnonil <sw...@gmail.com>]

Hello Everybody,

I am creating and sending messages from the "Send" tab in Active MQ Web
Console. I am setting the following parameters

1. Queue Name : BackupQueue
2. Persistent Delivery : true
3. Time to live : 300000 (5 minutes)
4. Message Body: "A message in a bottle"

But when I try to consume the message using the following code, the consumer
does not get invoked.


ActiveMQConnectionFactory connectionFactory = new
ActiveMQConnectionFactory(backUpServerUrl);
try
{
	Connection connection = connectionFactory.createConnection();
	Session session = connection.createSession(false,
Session.AUTO_ACKNOWLEDGE);
	MessageConsumer  consumer=
session.createConsumer(session.createQueue("BackupQueue"));

	consumer.setMessageListener(new MessageListener()
	{
		public void onMessage(Message message)
		{
			System.out.println("message = " + message);
		}
	});
	connection.start();
}
catch (JMSException e)
{
	LOGGER.log(Level.SEVERE, "", e);
}


The consumer does not get invoked even after 5 minutes (i.e after the
message has expired). It goes straight into the DLQ.

But then if I remove the Time to live parameter from the message, my
consumer gets invoked immediately. 
Can't I consume messages for which there is a preset time to live set?

Thanks and With Regards.

I'm not sure and I haven't checked the source-code, but could it be
that the field is actually setting the timestamp when the message is
going to expire instead of the TTL?

Best regards,
Martin

Figured out what the problem was. The producer sending messages had it's
clock ahead by ten minutes compared to the VM where the broker was running.

As soon as I set the expiry to more than 15 minutes the problem was solved.
