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.
Add the following ActiveMQ JMS-specific JAR files to <PRODUCT_HOME>/repository/components/lib/ directory.

Configuring the ActiveMQ input JMS event adapter

You can configure the ActiveMQ input JMS event adapter either using the management console or using a configuration file as explained below.

Configure using the management console

Follow the instructions below to configure ActiveMQ input JMS event adapter using the management console. This deploys the event adapter in the <PRODUCT_HOME> /

repository/ deployment/ server/ inputeventadaptors/ directory.

Start ActiveMQ, and then start the product.
Log in to the product's management console and click Configure.
Click Input Event Adaptors in the Event Processor Configs menu, and then click Add Input Event Adaptor.
Enter details as shown in the below example.
Click Add Event Adaptor.

Configure using a configuration file

Follow the instructions below to configure ActiveMQ input JMS event adapter using a configuration file.

Create an XML file with the following ActiveMQ input JMS event adapter configurations. Input event adapter implementation must start with <inputEventAdaptor> as the root element.

<inputEventAdaptor name="activemqJmsInputAdaptor" statistics="disable"
  trace="disable" type="jms" xmlns="http://wso2.org/carbon/eventadaptormanager">
  <property name="java.naming.provider.url">tcp://localhost:61616</property>
  <property name="transport.jms.SubscriptionDurable">false</property>
  <property name="java.naming.factory.initial">org.apache.activemq.jndi.ActiveMQInitialContextFactory</property>
  <property name="transport.jms.ConnectionFactoryJNDIName">TopicConnectionFactory</property>
  <property name="transport.jms.DestinationType">topic</property>
</inputEventAdaptor>

Add the XML file to <PRODUCT_HOME>/repository/deployment/server/inputeventadaptors/ directory. Since hot deployment is enabled, you can simply add/remove files to deploy/undeploy to/from the server.

After an adapter is successfully added, it gets added to the list of adapters displayed under Event Processor Configs in the Configure menu of the product's management console. Click Edit to change its configuration and redeploy it. This opens an XML-based editor allowing you to edit the event adapter configurations from the UI. Do your modifications and click Update . You can also delete it, enable/disable statistics or enable/disable tracing on it using the provided options in the UI.
