摘      要：Business Process Exeention Language （BPEL） is being used in various applications as the standard of workflow. 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.
