SERVICE PROCESSING SYSTEM, ITS PROCESSING METHOD AND ITS PROCESSING PROGRAM

PROBLEM TO BE SOLVED: To solve problems such that it takes long time for notifications to ends and the notification is not completed by a fault since the notification of cancellation in Web service items are made sequentially in a multi-stage Web service relying on the collaboration of a plurality of sub Web services provided by processing nodes distributed over a plurality of servers. SOLUTION: A Web service status management service is provided independently of processing nodes related to a Web service item. Information for uniquely identifying the status management service is added to messages transmitted and received between the processing nodes. Communication between each of the processing nodes and the status management service makes it possible for the status management service to record the status conditions of a specific Web service item. Then, a means is provided to directly transmit, according to the recorded status condition, a notification for cancellation of the item to the processing nodes related to the specific Web service item.
