【摘要】 EJB是J2EE服务器端的核心分布组件规范,为企业级分布计算提供了强有力的解决方案,在开发大型分布式应用系统中特别是电子政务、电子商务应用系统中表现出了强大的生命力。探讨了EJB的体系结构及其编程接口,提出了基于EJB的电子报税系统的模型框架,设计并实现了一个运行在J2EE服务器上的N层分布电子报税系统。更多还原

【Abstract】 The EJB is pivotal distributed component criterion of the J2EE application server,which provides a powerful solution for the enterprise distributed computation,and has shown mighty vitality in exploiting the large distributed application systems,especially E-government,electronic commerce application system.In this paper,the EJB architecture?programming interface are probed into at first,then the EJB-based model framework of the electron tax-declaring system is provided,and at last,an electron tax-declaring system with multi-tier distributed architecture is designed and implemented for the J2EE application server.更多还原
