Abstract

Differences in Web Service interfaces can be classified as signature or protocol incompatibilities, and techniques exist to resolve one or the other of these issues but rarely both. This paper describes complex event processing approach to resolving both signature and protocol incompatibilities existing between Web Service interfaces. The solution uses a small set of operators that can be applied to incoming messages individually or in combination to modify the structure, type and number of messages sent to the destination. The paper describes how CEP-based adapters, deployable in CEP engines, can be generated from automata representations of the operators through a standard process and presents a proof-of-concept implementation.
