Create a component in your web application. Base it on a class that implements the atg.dms.patchbay.MessageSink interface. For example, you can base the component on the atg.service.datacollection.MessageSinkDataListenerService class.

Add the Nucleus path of the event queue component to the dataListener property. See Example Event Listener Component.

Configure the Oracle ATG Web Commerce messaging system to send the events you are listening for to the event listener component. See Example Event Listener Component.
