The sender receives the event from the processing part via the direct-vm: component and does a technical conversion from the exchange header and body to a JSON format which is stored in the exchange body and all header fields of the event will be removed from the exchange.
After the conversion from the Exchange Event Structure to the JSON structure, the event (exchange body as JMS message) will be sent via the jms component (so far, only ActiveMQ Broker is supported in Talend ESB).
The jms destination can be configured in the org.talend.eventlogging.sender.jms.cfg file as follows:
sender.destination.jms.url=tcp://localhost:61616
sender.destination.jms.queue=event.logging.server
sender.destination.jms.username=tadmin
sender.destination.jms.password=tadmin
