Building High-Quality Print Management System Using XML Web Services

XML Web Services technologies are the preference technology to building eBusiness On Demand system. Such system carrys the characteristics of modulized, loosy coupled, extensible, platform and language-neutral, and high level of interoperability. Those characteristics are the demands of eBusiness development. Web services are the foundation of dynamic eBusiness and XML has been the extensively used on the Internet as a standard of data representation and exchange. XML Web Services are the footstone of eBusiness On Demand dynamic eBusiness.This paper implements an instance of eBusiness On Demand dynamic eBusiness system: Dolphin High-Quality Print Management (DHQPM) system and discusses the choice and application of corresponding techniques.DHQPM system can be divided into four function modules which are print-flow management, equipment and person management, material management, sales management. Applications are divided into four layers: User Interface layer which represents presentation logic, Virtual Dispatch Module, Module Facade, Server Side Component. And last three layer are based on Web Services.The implementation of above four function modules are different layer' s Web Services which using WSDL to describe services ,SOAP as a protocol of access services, and Tomcat, Axis to publish the services. XML data document can be used as parameters in order to make layer and layer exchange data. The system uses XML Schema to define the whole data schema, and JDOM to parse the XML document.To develop different layers, DHQPM system uses different language and platform which is an embodiment of platform and language-neutral characteristic. Modulized and loosy coupled characteristics will make the whole system easily extended as the demands increasing.
