Since most services on the Internet are mutually independent, users have trouble accessing several services to achieve a single purpose. For example, if a user wants to travel to Paris and Berlin, he/she has to access several hotel reservation services and airline reservation services. Solving this problem requires service composition technology, which constructs a composite service called a one-stop service by combining several independent services. Essential for service composition are one-stop service provisioning and collaboration technologies. One-stop service provisioning technology identifies services on the net that satisfy a user's needs and combines those independent services into a single service, and collaboration technology controls the one-stop service flow. In this paper, we propose a scenario-based service composition method to achieve one-stop services on the Internet using distributed object-oriented technology and workflow technology.
