How to define virtual Topic in Artemis

Solution Verified - Updated -

Environment

  • Red Hat AMQ
    • 7.2.x

Issue

  • Unable to define and use virtual topic
  • There seems to be two ways of using Virtual Topic in AMQ7.
    • using the Artemis FQQN comprised of the address and queue
Queue subscriptionQueue = session.createQueue("VirtualTopic.Orders::Consumer.C.VirtualTopic.Orders");
Error: Creating Queue: VirtualTopic.Orders::Consumer.C.VirtualTopic.Orders
Caught: xxx.yyy.JMSException: Address VirtualTopic.Orders is not configured for queue support [condition = amqp:illegal-state]

Resolution

  • With JMS1.1, a durable subscription is identified by the pair of clientId and subscriptionName. The clientId component must be unique to a connection on the broker.
  • JMS 2.0 adds the possibility of shared subscriptions with new API's that are fully supported in Artemis.
  • For example, a default 5.x consumer destination for topic VirtualTopic.Orders subscription A:
Queue subscriptionQueue = session.createQueue("Consumer.A.VirtualTopic.Orders");
    session.createConsumer(subscriptionQueue);
  • Test java client is attached
