Abstract： In distributed computing environment, workflow technologies have been continuously developed. Recently, there is an attempt to apply these technologies to context-aware services in ubiquitous computing environment. The middleware, which offers services in such environments, should support the automation services suited for the user using various types of situational information around the user. In this paper, based on context-aware workflow language (CAWL), we propose a CAWL based composite workflow handler for supporting composite workflow services, which can integrate more than two service flows and handle them. The test results shows that the proposed CAWL handler can provide the user with the composite workflow services to cope with various demands on a basis of a scenario document founded on CAWL.
Key words： ubiquitous computing; context-aware; composite workflow; context-aware workflow language (CAWL) handler
