摘要

Web Service processes in WS-BPEL have several non-functional requirements such as security and reliable messaging. Although there are many WS-~* specifications that address these concerns, their integration with WS-BPEL is still open. In this paper, we discuss these non-functional requirements and present a survey on the current support for their specification and enforcement in WS-BPEL engines. Moreover, we introduce an aspect-oriented container framework that uses a declarative deployment descriptor to specify the non-functional requirements. For the enforcement, aspects in AO4BPEL 2.0 are generated, which intercept the process execution and call dedicated middleware Web Services.
