Automated Web Service Composition System on Enterprise Service Bus

摘要

The fast and constant development of economic and computer network technology urges the building of enterprise integration platform, and quick delivery of new web services. These problems can be solved by applying technologies like Enterprise Service Bus (ESB) and automated web services composition. In this paper, we present an ESB based automated web service composition prototype. Our prototype D-Composer consists of two subsystems: Al planning subsystem and workflow binding subsystem. The former subsysteM takes users' requirement as input, uses an AI planning engine to construct an abstract workflow, and transforms it to the workflow binding subsysteM through ESB. The latter one binds appropriate service instances to the abstract workflow via a matchmaking engine, then generates a BPEL workflow, and executes it.
