Input Qpid JMS Event Adapter

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

Prerequisites

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

Install JMS-Qpid Broker and JMS-Qpid Client.
Add the following broker-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 input JMS event adapter

You can configure the Apache Qpid JMS input event adapter either using the management console or using a configuration file.

Configure using the management console

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

repository/ deployment/ server/ inputeventadaptors/ directory.

Log in to 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.

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'
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 Qpid input event adapter configurations. Input event adapter implementation must start with <inputEventAdaptor> as the root element.

<inputEventAdaptor name="QpidJmsInputAdaptor" 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="transport.jms.SubscriptionDurable">false</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>
</inputEventAdaptor>

Add the XML file to the <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.
