Apache ActiveMQ™ is the most popular and powerful open source messaging and Integration Patterns server.
Apache ActiveMQ is fast, supports many Cross Language Clients and Protocols, comes with easy to use Enterprise Integration Patterns and many advanced features while fully supporting JMS 1.1 and J2EE 1.4. Apache ActiveMQ is released under the Apache 2.0 License

Habari Client for ActiveMQ is a library for Delphi and Free Pascal which provides easy access to Apache ActiveMQ, the popular open source Message Broker.
With this library, developers can build integrated solutions, connecting cross language clients and protocols from Java(tm), C, C++, C#, Ruby, Perl, Python, and PHP, using the peer-to-peer or the publish and subscribe communication model.
Habari Client for ActiveMQ uses a plug-in style architecture for communication libraries and message transformers for XML and JSON object serialization.
It supports Delphi 2009 to XE2 and Free Pascal, and follows the specification of the JMS API for Message Oriented Middleware.
Core elements of the Habari Client Library API.
| Feature | Example | Description |
|---|---|---|
| Message types | Msg := Session.CreateTextMessage('Hello World!'); |
Supported message types: TextMessage, BytesMessage, ObjectMessage, MapMessage |
| Destination types | Queue := Session.CreateQueue(TestQueue); Topic := Session.CreateTopic(TestTopic); |
Queues and Topics provide message exchange using the peer-to-peer or the publish and subscribe communication model. |
| Expiration | MessageProducer.Send(JMSMessage, dmNonPersistent, DEFAULT_PRIORITY, TIMETOLIVE); |
Message expiration can be used to limit the time to live of a message. |
| Priority | MessageProducer.Send(JMSMessage, dmNonPersistent, DEFAULT_PRIORITY, TIMETOLIVE); |
Messages can use priority headers. |
| Properties | Msg.SetStringProperty('nickname', 'jane'); |
Messages can carry properties for meta data. With most message brokers, message consumers can define filters to receive only messages with matching properties. (check featue matrix for supported brokers) |
High-level features of Habari Client Libraries for JMS message brokers.
| Feature | Example | Description |
|---|---|---|
| Persistent messages | MessageProducer.Send(JMSMessage, dmPersistent, DEFAULT_PRIORITY, TIMETOLIVE); |
Persistent Messages survive a broker restart. |
| Transacted Sessions | Session.Rollback; |
Transacted sessions can use Commit and Rollback. |
| Durable topics | Consumer := Session.CreateDurableSubscriber(Topic, SubName); |
If a client needs to receive all the messages published on a topic, including the ones published while the subscriber is inactive, it uses a durable subscriber. |
| Failover and load balancing | URL := 'stomp://primary,stomp://secondary'; |
Select the server in a random or round-robin order, and connect to the next if a connection can not be established. |
| JMS Selector | Consumer := Session.CreateConsumer(Destination, 'color = ''red'''); |
Filter messages by header properties. |
| Object Serialization | Msg := Session.CreateObjectMessage(MyObject); |
Support for NativeXml and OmniXML. |
