Enterprise Java integration with Delphi and Free Pascal applications - new release 2019.02

[M. Justin]

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

   IMessageProducer

   IMessageConsumer

   IMessage (and its subclasses)

   IDestination (and its subclasses)

There is also a new simple API which introduced these interfaces:

   IMQContext

   IMQProducer

   IMQConsumer

Code example using the new API:

procedure TNewApiTests.TestSendMessage;
var
  Factory: IConnectionFactory;
  Context: IMQContext;
  Destination: IQueue;
  Producer: IMQProducer;
  Consumer: IMQConsumer;
  TextMessage: ITextMessage;
begin
  Factory := TBTConnectionFactory.Create;
  
  Context := Factory.CreateContext;
  try
    Destination := Context.CreateQueue(GetQueueName);
 
    Producer := Context.CreateProducer;
    Producer.Send(Destination, 'Hello World');
 
    Consumer := Context.CreateConsumer(Destination);
    TextMessage := Consumer.Receive(2500) as ITextMessage;
 
    CheckEquals('Hello World', TextMessage.Text);
  finally
    Context.Close;
  end;
end;

Delphi and Java example code for application integration with the libraries is included or available online.
