other applications. Instead, messages are sent to destinations, known as queues or topics. The JbMQTopicTest monitors the topics on the JBoss server.

The number of durable subscribers to the topic. Messages meant for a durable subscriber are stored in the persistent cache even when the subscriber is inactive. These messages are delivered to durable subscribers when they connect to the server. |
