As the requirerments increase to describe application processes in BPEL, BPEL documentt is getting more Complplicated. Therefore it is difficult to describe applications in BPEL with high reliability. In order to write highly reliable BPEL document, it is necessary to check if the document is working correctly in accordance with user＇s intention. But it is difficult to carry out the test since BPEL engine doesn＇t provide a profiling function. In this paper, we suggest a BPEL system with a real-time profiling function. The suggested system consists of an integrated development environment and a BPEL nunning environment. BPEL integrated development environment has a BPEL to Java（B2J） engine, which generates and executes a Java workflow program from a BPEL document, and a converter, which converts Java Weaving XML （JWX） documents to Aspect-oriented programs. The new functions are described in JWX, which is Extensive Markup Lan-guage （XML）-based document. Since aspect-oriented programming technique provides the way to modularize main and supplemental requirements, it guarantees the low degree of coupling between BPEL workflow program and new functions by weaving them. Our approach can be extended to add other functions to provide context-aware services.展开更多

A developer can describe the robot services that are proper to users＇ envir onments by using his or her various environments, and process them through the execution engine. However, it is difficult for a developer to describe and develop robot services, who knows all surrounding information which is called context infor mation. If there is a method for describing and documenting robot services in intuitive expressions, that is to use graphical user interfaces（GUls）, it would be very helpful. This paper suggests that robot service developers describe robot services us ing intuitive GUls with contextawareness. And the services can be automatically generated into workflow documents. Robot services that robot service developers have made with intuitive GUIs can be automatically generated into workflow docu ments by using the object modeling technique（OMT）. Developers can describe robot services based on contextaware work flow language（CAWL ）. For testing, scenariobased robot services are described using CAWLbased development tool, and their workflow documents are automatically generated.展开更多
