The Design And Realization Of A Model Of The Integration Framework Using The Web Architecture Based On SOAP/XML

This paper mainly focuses on building a n-tier integration Model for allowing thin clients using XML lathered in soap to access SOAP and legacy applications by using the architecture of Knowledge-Based System (KBS). SOAP is the kernel communication protocol of Web Service, which much help set up a connection rule between different kind of applications . The shortcoming of the architecture of web service is that it is lack of central control. On the contrary, KBS has the central control of its components. However, many KBSs is now facing the challenge of new techniques and is in danger of out-of-date. Therefore, it will be very meaningful to bring out a new architecture model that avoids the shortcomings of KBS and Web Service Architecture. And SOAP is the key to solve this problem and realize this model.The main task of this paper is list as follows: Register dynamically the wrappers that wrapper different kind of legacy applications and control them; Realize SOAP cache and security mechanism by using OpenLDAP and JNDI. For SOAP applications, we use dynamic proxy factory to realize the integration.This paper makes some contributions on bringing out the architecture that combines SOAP service and Knowledge-Based System, especially setting up criterions for dynamically registering wrappers that wrapper legacy application.This paper firstly discusses the background, needs and meaningfulness of this subject, and then analyzes the research status abroad and homeland thereby draws conclusion on the possibility of combining SOAP and KBS. And then by using sample applications, we bring out an integration architecture model and discuss the means and techniques of the realization of each module.
