About

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.

Connect Delphi and Free Pascal applications with WildFly 12 Final

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

Download

• • download and extract WildFly 12.0.0.Final (requires JDK 8 or newer)
    
  • download and extract Habari Client for Artemis demo applications

Server configuration

• run <inst>wildfly-12.0.0.Final\bin\add-user and add the application user chat with password chat and role guest
• edit <inst>wildfly-12.0.0.Final\standalone\configuration\standalone-full.xml to enable STOMP and add the ExampleTopic destination (see below)

<subsystem xmlns="urn:jboss:domain:messaging-activemq:3.0">
<server name="default">
 ...
  <acceptor name="stomp-acceptor" factory-class="org.apache.activemq.artemis.core.remoting.impl.netty.NettyAcceptorFactory">
    <param name="protocols" value="STOMP"/>
    <param name="port" value="61613"/>
  </acceptor>
  ...
  <jms-topic name="ExampleTopic" entries="java:/jms/topic/ExampleTopic" />
  </server>
</subsystem>

Launch server and clients

1. start WildFly with <inst>wildfly-12.0.0.Final\bin\standalone -c standalone-full.xml
2. launch one or more instances of the HabariChat demo application and connect to the server on localhost with user chat and password chat

The Delphi application now can use the ExampleTopic as the ‘chat room’ for messages between all running instances (and, of course, allows also non-Delphi clients to receive and send messages within this chat room topic as well).
