The OrderFulfiller sends the FulfillerOrderFragment message to the various fulfillment systems responsible for sending out the products in the shipping groups. All shipping groups in an order with the same fulfiller are sent in FulfillerOrderFragment. The FulfillerOrderFragment message contains the shipping group IDs.

The FulfillOrderFragment message, like all of the other messages in fulfillment, is a serializable object contained within a JMS object message. The message includes a serialized order and the list of shipping groups IDs included in this fragment. This message is sent by the OrderFulfiller to the various fulfillment systems responsible for fulfilling the shipping groups. When this message is sent, control of the object is transferred to the system that receives the message. By default, this system is the HardgoodFulfiller.
