Question

I create a destination like this:

 Destination destination = session.createQueue("queue_name");

In this case if the queue named “queue_name” dont exist, it will be created.

I want to form a destination to a queue and in case it dont exist, i dont want to create it.

Is there a way to connent to a queue only if it exists?

I think you should be able to get a list of the available queues using DestinationSource from your connection. The you could look to see if the queue exists.

Havnt tried it, but think it looks like this:

        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
        ActiveMQConnection connection = (ActiveMQConnection)connectionFactory.createConnection();
        DestinationSource ds = connection.getDestinationSource();
        Set<ActiveMQQueue> queues = ds.getQueues();
