【 摘 要 】
This paper focuses on middleware concerns in BPEL workflows. When looking at those workflows from the implementation perspective, we observe that they have several BPEL-specific middleware requirements, which are not supported by current WS-* specifications and by most BPEL engines available to date. This demo paper will show the AO4BPEL Engine, which implements a container framework that allows the specification and enforcement of middleware requirements in BPEL processes. A deployment descriptor is used to specify the quality of service requirements of BPEL activities. A light-weight and aspect- based process container is used to enforce those requirements by calling dedicated middleware Web Services. We implemented those middleware Web Services by extending open source implementations of WS-* specifications for security, reliable messaging, and transactions.
