With Habari Client libraries, you can take advantage of message broker / message queue technology - which is distributed, loosely coupled, reliable and asynchronous - to build integrated systems, connected using peer-to-peer or publish-subscribe communication models.
Supported message brokers include Apache ActiveMQ, Apollo, HornetQ, Open MQ, and RabbitMQ.
All library versions use the same high-level API and programming model.
For more information, please select the Habari Client library for your message broker. The demo application download files include the broker-specific "Getting Started" documentation (PDF).

Temporary queue support in Habari Client libraries
Temporary queues are destinations with a scope limited to the connection that created it, and are removed on the server side as soon as the connection is closed. They are typically used for synchronous messaging (request/reply communication model).
