1. Using the distributor's web interface, a department store buyer submits an order for multiple products. An HTTP request is sent to the "OrderReceiver, an HTTP binding component (BC). ⁴
2. The OrderReceiver sends the message to an "OrderRouter" Service Engine (SE) ⁵ component. This SE is responsible for parsing the order and deciding, based on the message content, which OrderTransformer should receive which part of the message (i.e., an order for a product).
3. The OrderRouter publishes the order to the appropriate JMS topic. It decides which topic to publish to based on message content. Specifically, the OrderRouter publishes the messages based on which wholesaler sells the item.
4. The OrderTransformer is a Service Engine component, which modifies the message and puts it in a format which is readable by the wholesaler interface that will fullfill the order.
5. Each OrderTransformer sends the modified message to the OrderProcessor.
6. The OrderProcessor is a Binding Component that has two functions. The OrderProcessor places an order to the appropriate wholesaler through the wholesaler's Webservice or propriety interface.
7. The OrderProcessor also publishes a message about the order on a topic.
8. The message on the topic is subsequently picked up by the BusinessMonitor component. This component monitors the orders for quality assurance.
