Since 2008, 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.
These STOMP 1.0/1.1/1.2 client libraries enable Java to Delphi (or Free Pascal) communication over standalone message brokers or with the messaging subsystem in open source Java EE application servers such as WildFly and Payara.
Four library versions are available, specialized for different message brokers:
Habari Client for ActiveMQ
Habari Client for Artemis
Habari Client for OpenMQ
Habari Client for RabbitMQ
Habari Client libraries use a programming model based on these core interfaces:
IConnectionFactory - creates server connections
IConnection - represents a server connection
ISession - represents a server session
IMessage (and its subclasses)
IDestination (and its subclasses)
There is also a new simple API which introduced these interfaces:
