ActiveMQ JMS output event adapter can be used to publish events having map, XML, JSON, and text formats via jms transport.

Prerequisites

Follow the steps below to set up the prerequisites before starting the configuration.

  1. Install Apache ActiveMQ JMS

    Icon

    This guide uses ActiveMQ versions 5.7.0 or below. If you want to use a later version, for instructions on the necessary changes to the configuration steps, go to Apache ActiveMQ Documentation.

  2. Add the following ActiveMQ JMS-specific JAR files to  <PRODUCT_HOME>/repository/components/lib/ directory. 
    • <ACTIVEMQ_HOME>/lib/activemq-core-xxx.jar  
    • <ACTIVEMQ_HOME>/lib/geronimo-j2ee-management_1.1_spec-1.0.1.jar
  3. Refer the <PRODUCT_HOME>/reposiyory/conf/jndi.properties file to register a connection factory and add the topics to be sent to the ActiveMQ broker. This example uses Topic Connection Factory. Therefore, the following entry points the default ActiveMQ host to localhost and port to 5672: 

    connectionfactory.TopicConnectionFactory=amqp://admin:admin@clientid/test?brokerlist='tcp://localhost:5672'

    topic.topicMap = topicMap
    topic.topicText = topicText

  4. Start ActiveMQ, and then start the product.
