Event listener components function as message sinks in the Oracle Commerce Core Platform messaging system, which uses the Java Messaging System (JMS). Event listener components are based on classes that implement the atg.dms.patchbay.MessageSink interface and they are configured as message sinks in the messaging system patch bay. See information about the Core Platform messaging system in the Platform Programming Guide.

When the components receive events from the messaging system, they send event objects to event queue component. See Event Queue Component. The data listener property of the event listener component stores references to the event queue components.

Event listener components send the event objects they receive to event queue components. They store the Nucleus paths of the event queue components in a configuration property that is typically named dataListeners or dataListener. For example:

dataListener=/mycompany/reporting/datacollection/MyEventQueue
