[Sample] Order Processing Process

This sample illustrates usage of WS-BPEL 2.0, WS-HumanTask 1.1 and Rule capabilities in WSO2 Business Process Server and WSO2 Business Rule Server.

Order Processing Flow

• The client place an order by providing client ID, item IDs, quantity, shipping address and shipping city.
• Then Process submits order information to invoicing web service, which generates order ID and calculate total order value.
• If total order value is greater than USD 500, process requires a human interaction to proceed. When a order requires a human interaction process creates a Review HumanTask for regional clerks. If review task is rejected by one of regional clerk user, workflow terminates after notifying the client.
• Once the regional clerk approve the review task, workflow invokes Warehouse Locater rule service to calculate nearest warehouse.
• Once receiving nearest warehouse, process invokes Place Order web service to finalize the order.
• Finally user will be notified with the estimated delivery date.
