Output Qpid JMS Event Adapter

The configurations of the Apache Qpid output JMS event adapter are explained below. You can configure it with map, XML, JSON, and text output  mapping types.

Prerequisites

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

1. Install Qpid JMS Broker and Qpid JMS Client.

2. Add the following Qpid JMS-specific JAR files to  <PRODUCT_HOME>/repository/components/lib/ directory.   
   
   • <ACTIVEMQ_HOME>/lib/geronimo-jms_1.1_spec-1.0.jar   
   • <QPID-CLIENT_HOME>/lib/qpid-client-xxx.jar
   • <QPID-CLIENT_HOME>/lib/qpid-common-xxx.jar 

Configuring the Qpid output JMS event adapter

You can configure the Qpid output JMS event adapter using the management console or using a configuration file as explained below. This deploys the event adapter in the <PRODUCT_HOME>/repository/ deployment/ server/ outputeventadaptors/ directory.

Configure using the management console

Follow the instructions below to configure JMS Qpid output event adapter.

1. Log in to the product's management console, and click Configure.

2. Click Output Event Adaptors in the Event Processor Configs menu, and then click Add Output Event Adaptor.

3. Enter details as shown in the below example.

   Refer the <PRODUCT_HOME>/reposiyory/conf/jndi.properties file. This example uses Topic Connection Factory. Therefore, the following entry points the default Qpid host to localhost and port to 5672:
connectionfactory.TopicConnectionFactory = amqp: //admin:admin@clientid/test?brokerlist='tcp://localhost:5672'

   

4. Click Add Event Adaptor.

Configure using a configuration file

Follow the instructions below to configure Qpid output JMS event adapter using a configuration file.

1. Create an XML file with the following Qpid output event adapter configurations. Output event adapter implementation must start with <outputEventAdaptor> as the root element. 

   <outputEventAdaptor name="QpidJmsOutputAdaptor" statistics="disable"
     trace="disable" type="jms" xmlns="http://wso2.org/carbon/eventadaptormanager">
     <property name="java.naming.provider.url">repository/conf/jndi.properties</property>
     <property name="java.naming.factory.initial">org.apache.qpid.jndi.PropertiesFileInitialContextFactory</property>
     <property name="transport.jms.ConnectionFactoryJNDIName">TopicConnectionFactory</property>
     <property name="transport.jms.DestinationType">topic</property>
   </outputEventAdaptor>

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