Artemis is a "new" JMS2-compatible message broker based on a merging of the ActiveMQ and HornetQ codebases, and represents the future of both projects.

Immutant is built on an abstraction layer called WunderBoss in order to share much of the implementation with our sibling project, TorqueBox. An additional advantage of this layer is it allows us (in theory) to easily switch out the underlying messaging implementation while keeping the same Clojure API. With the release of Artemis 1.0.0, we've now taken the opportunity to test that theory.

wunderboss-artemis

With only a couple of changes to WunderBoss that allow us to share the bulk of the existing JMS2 implementation between the HornetQ and Artemis adapters and make it easier to exclude the HornetQ dependencies, we're now able to provide wunderboss-artemis. It allows you to use Artemis instead of HornetQ as the message broker in an embedded application (it doesn't yet support Artemis if you are deploying to WildFly).

If you want to give it a try, you just need to depend on a recent incremental build (#585 or newer) and make a few adjustments to your :dependencies:

:dependencies [[org.immutant/messaging "2.x.incremental.585"
                :exclusions [org.projectodd.wunderboss/wunderboss-messaging-hornetq]]
               [org.projectodd.wunderboss/wunderboss-artemis "0.1.0"]]

If you then use messaging and see something like the following in your log output, you're all set!

14:12:44.471 INFO  [org.apache.activemq.artemis.core.server] (main) AMQ221020: Started Acceptor at localhost:5445 for protocols [CORE]
14:12:44.471 INFO  [org.apache.activemq.artemis.core.server] (main) AMQ221007: Server is now live

Artemis is brand new - once it matures a bit, we may provide an immutant-artemis lib that would bring in wunderboss-artemis and provide an Artemis management namespace similar to the immutant.messaging.hornetq we currently provide.
