Message Broker Using Asynchronous Method Invocation in Web Service and Its Evaluation

Event driven architectures are widely used in numerous software applications, for instance in GUI focused software. Currently most event driven softwares are applied merely in local environment. If we need to use event driven architecture in a distributed environment, there are not too many candidates to choose from. Thus, although there are a number of techniques which support the event notification in distributed environments, such as Comet technique and ESB platform, we still require a light-weight and user-friendly system, free from platform and protocol, to support event notification in the Web environment. In this paper we implemented a middleware which supports event subscription and publication based on Web Service. Through the evaluations afterwards we finally found out the limitations of our current system and we offered our suggestions accordingly.
