【摘要】 当今Internet上企业级应用迅速发展，许多商业服务由传统媒体向Internet上转移，许多大的商业公司都看好这个巨大的网上市场，希望快速开发出高质量的网上商业应用系统，同时用户的系统需要不断的升级、更新。而传统模式大大限制了系统的开发效率，系统升级比较困难，需要做大量的工作，系统更新过程将影响系统的正常运行，导致服务的暂时性中断。分布式组件对象技术CORBA的发展与成熟为解决这些问题提供了一种很好的方案。本文在分析了CORBA机制、Java、Web的最新技术特点的基础上，实现了CORBA、Java、Internet三者的整合，并以这种整合机制为基础开发了一个方便网上应用系统开发的支撑平台。平台采用三层体系结构，开发出的组件对象符合CORBA标准，在可移植性、可扩充性方面都优于传统客户机/服务器模式，便于应用系统的无缝可扩充。给出了平台应用系统的整体构架、体系结构和平台中几个模块的实现要点，以及本文的进一步的工作。更多还原

【Abstract】 Today, enterprise application on Internet is developing quickly and some kinds of services are switching to base on Internet. So more and more enterprises hope to develop application system on Internet quickly . At the same time ,they hope that their system can extend and update easily .And that the tradition developing mode limits the efficiency of software developing and makes it difficulty to update and upgrade the old systems ,because lots of works have to be done and system can抰 run normally and the services are inevitably interrupted during the process of updating old system. CORBA ,the technology about distributed components , is growing up to solve these problems nicely. We analyzed the recently technology of CORBA~. Java and Web, implemented a style of integration of CORBA .~. Java and Internet .Based on this integration we developed a platform used to support developing application system on Internet . This platform adopts the three tiers architecture and The components developed by using this platform are in accordance with the CORBA standards, which makes it easy to extend and update the application system seamlessly. It is befter than the old C/S developing mode. This paper also introduces the whole structure of the platform and the outline of some modules and our future work.更多还原
