【摘要】 随着通信和计算机技术的迅速发展,以及个人移动通信设备尤其是手机的普及和分布式网络应用程序的需求的扩展,传统的直接面对面的商务洽谈和基于PC机的商务运作模式已不能满足人们商务甚至日常生活的需求。面对这种矛盾,一种全新的基于移动设备的商务模型—移动Web服务正得到广泛的关注和快速的发展。有了移动Web服务,企业内部就可以实现流动办公,提升企业或个人的营运作业效率,同时针对广大终端用户,他们可随时随地获取所需的教育、医疗、交通、饮食、商务和娱乐服务。 鉴于J2ME和Web服务的一些优点,我们采用将这两种技术结合来进行移动电子商务应用系统的研究和开发。 (1)本文结合Web服务技术、J2ME技术和XML消息流技术以及SVG技术介绍了如何构建移动Web服务系统,此系统支持应用的动态集成,具有很好的可扩展性。同时,它应既支持传统的Web方式的浏览,也支持WAP手机,PDA手机,J2ME手机等多种无线终端设备。 (2)为了更好的阐述这个动态集成的移动Web服务平台,本文在J2ME和Web服务这两种技术的理论基础上,介绍笔者开发一个这两种技术结合的移动Web服务程序。其中J2ME用于手机端的开发,包括所有手机应用程序都必须具有的三个要素:图形用户界面、输入输出及其与网络的连接:而Web Services则用于处理服务器端和客户端之间的交互、以及后台服务端程序的发布。 (3)这个移动Web服务系统包括三个子模块:天气预报服务、购物车服务、地图显示服务。文章简述了相关技术后,在第五和第六章详细说明该系统的实现。重点结合源码介绍了Web Services的发布,以及在手机端利用J2ME进行开发,包括线程的应用、会话的维持等。更多还原

【Abstract】 With the rapid development of communication and computer technology, the popularity of mobile communication equipment, and the enlargement of requirement for the application in the distributed network, it can’t be satisfied with the people business even daily life that the business fair of traditional face-to-face and the operation model based on PC. Face to the problem, a new business operation model based on the mobile equipment is concerned with and developed rapidly. Operation anywhere can be realized for enterprise with mobile Web Service, which can promote the enterprise or personal efficiency. At the same time, the end-user can get the services of education, medical treatment, traffic, diet, business and amusement whenever possible.For their advantages, J2ME and Web Services are adopted in the research and development work of our mobile e-business system.(1) The M-Commerce platform is based on Web services, J2ME, XML message flow and SVG It supports the dynamic integration, is easy to expand, and can be accessed from different mobile devices, such as WAP browser, PDA, mobile device with J2ME, or web browser.(2) For a better explanation for the dynamic integrated mobile Web Services platform, the paper lays emphasis on introduction how to realize a mobile Web Services application on the base of two technologies integrate J2ME and Web Services technology t. J2ME technology is used to develop the mobile client that the three basic elements of mobile application development: UI, I/O, and network connection, and Web Services to achieve the communication between client and server.(3) This system includes three sub-modules that are a weather forecast service, a shopping car service and a displaying map service. Writer illustrated the implementation of the system in detail at the fifth chapter and sixth chapter after discussed the relative technologies. Writer introduced how to publish Web Services and how to develop the mobile client by J2ME by showing some exact code. The mobile client development includes applying thread, session maintenance and so on.更多还原
