Earlier this year, Red Hat released WildFly 12 Final, a free and open source Java EE application server for the Java platform. If you need to exchange data between Delphi or Free Pascal code and WildFly, you can follow these steps for a quick demonstration of the Habari Client for Artemis library from Habarisoft
This article presents and compares the origins, architectures, and use cases of Apache Kafka, which is designed for high volume publish-subscribe messages and streams, and RabbitMQ, a general purpose message broker.

The RabbitMQ team announced the release of RabbitMQ 3.6.10. This release contains bug fixes and usability improvements. Binary and source distributions of the new release can be found on the downloads page, GitHub, Package Cloud, and Bintray. The RabbitMQ team encourages all users of earlier versions of RabbitMQ to upgrade to this latest release.
Habarisoft released new versions of Habari Client libraries for Delphi and Free Pascal application integration with popular free open source message brokers. This release has been tested with Apache ActiveMQ 5.14.5, Apache ActiveMQ Artemis 2.0, OpenMQ 5.1.1 and RabbitMQ 3.6.9. It contains enhancements and better test case organization of the included DUnit / FPCUnit test projects, which now prefer Stomp 1.2 over Stomp 1.0. It also introduces the IConnectionInfo interface, which returns broker version string and Stomp version of the current connection. Starting with this release, the library requires Delphi 2009 or Free Pascal 3.0.2 (or newer), it is not compatible with non-Unicode versions of Delphi. The internal version numbers of all client libraries in the 2017.04 release is 5.0.0.

Habari Client libraries enable Object Pascal applications to take advantage of message broker / message queue technology – which is distributed, loosely coupled, reliable and asynchronous – to build integrated systems, using peer-to-peer and publish-subscribe communication models.
One outstanding feature of the popular Apache ActiveMQ message broker is its rich message conversion capability, which allows cross-platform/cross-language exchange by serialization of JMS object and map messages to XML or JSON. Non-Java clients do not have to support the native ActiveMQ wire protocol. Instead, they can use a simple protocol such as STOMP.
The RabbitMQ STOMP plugin supports advanced queue features, which can be defined in the management interface but also from clients when the queue is created. No matter how these features have been declared, RabbitMQ requires that the client specifies the same feature settings anytime when this queue is used.
