Model of Networked Market System Based on XML and EJB

基于XML和EJB的企业网络化销售系统结构模式,是将所有客户端请求导入前端控制器,中心对象处理所有请求,决定下一视图。其业务逻辑和数据存取/修改的实现,利用了Java Bean通过JNDI定向到相应EJB组件。EJB组件将数据结果返回给视图生成XML格式的数据流,并将数据流及其样式单文件发送给客户端。客户端调用样式单文件,解析XML数据流显示结果。通过对系统表示逻辑、前端控制、业务逻辑,业务数据、EJB组件定位和开发流程的分析,设计了包括产品虚拟仓库、系统安全、订单管理等功能模块和界面视图控制、业务会话和数据操作等的电器产品网络化销售系统。

In the frame mode of enterprise networked market system based on XML and EJB, All of the requests of client server are sent to front-end controller. Center object process the requests and decide the next view. The business logic and data store/change was realized using Java Bean directs to EJB via JNDI. EJB sent data result to the view to create data stream in XML, and sent the data stream and style sheet to client end. The client end parsed the XML data stream via style sheet and shown the result. Based on the analyzing presentation logic, front controller, business logic, business data, EJB, development process, the electric products networked market system was designed, that includes function modules of product virtual store, system security and order management, and interface control, dialogue and data operation.
