Abstract：Business process execution language (BPEL) is a most recognized standard workflow language. However, it is difficult to be used in the ubiquitous system computing environment because it is difficult to describe the context information in the selection of the flow through the branch. To solve this problem, we propose a new BPEL workflow system with context-awareness by using aspect-oriented programming (AOP). This system is composed of a BPEL system module and a weaving module using AOP for context-aware. The BPEL system module generates a BPEL workflow program. And the weaving module converts a context-aware mark-up language (CAML) document to the aspect-oriented program that is applied to context-aware code without modification of the existing BPEL document. We also define a new document form that is called CAML, which provides a context-aware that is not available in BPEL. The system can generate a context-awareworkflow program. It is developed in a way that inserts context information using AOP to provide context-aware services.
Key words：aspect-oriented programming (AOP); business process execution language (BPEL)；context-aware workflow
