Configure using a configuration file

Follow the instructions below to configure WSO2 MB input JMS event adapter using a configuration file.

When using WSO2 MB 2.0.1 as the input event adapter follow the syntax Burl :{topic} at the time you define the topic, which is a message-related property . Add Burl: as the prefix of the actual topic.

  1. Create an XML file with the following WSO2 MB input event adapter configurations. Input event adapter implementation must start with    <inputEventAdaptor>  as the root element.

    <inputEventAdaptor name="MBJmsInputAdaptor" 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.wso2.andes.jndi.PropertiesFileInitialContextFactory</property>
      <property name="transport.jms.ConnectionFactoryJNDIName">TopicConnectionFactory</property>
      <property name="transport.jms.DestinationType">topic</property>
    </inputEventAdaptor>
  2. 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.
