Habari STOMP Client for ActiveMQ

Version 8.4, tested with ActiveMQ 5.18.3

Habari STOMP Client for ActiveMQ is a high-level, object-oriented Stomp client library for Delphi and Free Pascal which provides access to the ActiveMQ free open source message broker.

language

With this library, developers can build integrated solutions, connecting cross language clients and protocols, using the peer-to-peer or the publish-and-subscribe communication model.

favorite_border

It is easy to configure and provides a high-level API and programming model, based on connections, sessions, destinations, message producers, and message consumers.

filter_list

The library uses the Stomp protocol for its communication with the message broker. Supported Stomp protocol version levels are 1.0, 1.1 and 1.2.

Habari STOMP Client libraries support broker-specific extensions of the Stomp specification. Most of them can be accessed with the same client side code across all broker versions.

timer

Message Expiration

By default, a message never expires. If a message will become obsolete after a certain period, however, you may want to set an expiration time for the message.

traffic

Message Priority

A client can specify a priority for each message it sends. Message priorities affect the order in which the messages are delivered to the consumers.

storage

Persistent Messages

Brokers support reliable messaging by allowing messages to be persisted so that they can be recovered if there is failure which kills the broker.

Durable Subscriptions

Even if the client which created the durable subscription is not online, he can still get a copy of all the messages sent to the topic when he comes back online.

Code Examples

Message Producer Example

code

Code for sending (producing) messages:

// Getting connection from the server and starting it
ConnectionFactory := TBTConnectionFactory.Create;

try
    Connection := ConnectionFactory.CreateConnection;
    Connection.Start;

    // Messages are sent and received using a Session. We will
    // create here a non-transactional session object. If you want
    // to use transactions you should set the first parameter to 'true'
    Session := Connection.CreateSession(False, amAutoAcknowledge);

    // Destination represents here our queue 'ExampleQueue' on the
    // server. You don't have to do anything special on the
    // server to create it, it will be created automatically.
    Destination := Session.CreateQueue('ExampleQueue');

    // MessageProducer is used for sending messages (as opposed
    // to MessageConsumer which is used for receiving them)
    Producer := Session.CreateProducer(Destination);                

    // We will send a small TextMessage saying 'My hovercraft is full of eels' in Mandarin:
    TextMessage := Session.CreateTextMessage("我的氣墊船裝滿了鱔魚");

    // Here we are sending the message
    Producer.Send(Message);
finally
    Connection.Close;
end;

Message Consumer Example

code

Code for receiving (consuming) messages:

// Getting connection from the server and starting it
ConnectionFactory := TBTConnectionFactory.Create;

try
    Connection := ConnectionFactory.CreateConnection;
    Connection.Start;

    // Messages are sent and received using a Session. We will
    // create here a non-transactional session object. If you want
    // to use transactions you should set the first parameter to 'true'
    Session := Connection.CreateSession(False, amAutoAcknowledge);

    // Destination represents here our queue 'ExampleQueue' on the
    // server. You don't have to do anything special on the
    // server to create it, it will be created automatically.
    Destination := Session.CreateQueue('ExampleQueue');

    // MessageConsumer is used for receiving messages (as opposed
    // to MessageProducer which is used for sending them)
    Consumer := Session.CreateConsumer(Destination);                

    // We will try to receive a TextMessage within 5 seconds:
    TextMessage := Consumer.Receive(5000);

    WriteLn(TextMessage.Text);

finally
    Connection.Close;
end;
