Mapping JMS Concepts to the Core API

This chapter describes how JMS destinations are mapped to Apache ActiveMQ Artemis addresses.

Apache ActiveMQ Artemis core is JMS-agnostic. It does not have any concept of a JMS topic. A JMS topic is implemented in core as an address with name=(the topic name) and with a MULTICAST routing type with zero or more queues bound to it. Each queue bound to that address represents a topic subscription.

Likewise, a JMS queue is implemented as an address with name=(the JMS queue name) with an ANYCAST routing type associated with it.

Note: While it is possible to configure a JMS topic and queue with the same name, it is not a recommended configuration for use with cross protocol.
