The following image shows the architecture of JMS message queue and explains how an asynchronous SIF request is processed:
An external application sends a message containing a service invocation request to the
siperian.sif.jms.queue
inbound queue. The application server polls the queue for messages. The MDB of the Hub Server forwards the service request to the MDM Hub for processing. The MDM Hub processes the request and posts a response to the specified JMS outbound message queue. The external application retrieves the message from the specified message queue and processes it.
