【摘要】 移动Web服务是Web Service技术在移动设备方面的应用之一,它已成为新时期移动服务系统设计的趋势。目前虽然也有相应的服务系统出现,但由于各方面的局限性,这些服务系统还不完善。因此本文就Web Services在手机服务系统中的核心问题进行了研究。 J2ME是Java语言三大平台之一,它主要针对资源受限设备进行应用程序的开发,同时,Web服务能够让任何平台上的用任何语言编写的服务进行交互,使得应用程序的集成可以做到更快、更容易而且具有更高的可扩展性。鉴于J2ME和Web Services的一些优点,我们采用这两种技术来进行移动服务系统的研究和开发。 本文以基于Web Services的手机服务系统的开发为线索,进行了相关理论的研究、实验和技术开发。主要包含以下工作:(1)详细阐述了J2ME技术,主要针对其体系结构进行分析。(2)对Web Services技术的结构及其在后台服务器端的应用进行了分析。(3)基于Web Services实现的手机服务系统,对手机服务系统开发的一些关键问题进行研讨,包括:①Web Services在本服务系统中的实现模型;②本手机服务系统实现的架构和工作原理;③本服务系统中各个子服务的流程图。(4)详细说明手机服务系统的实现。重点介绍了Web Services的服务器端系统的各个子服务的开发与发布,以及利用J2ME来开发本服务系统的客户端。本服务系统的实现是基于Web Services的,同其它类似系统相比,其优势也是明显的,主要体现在动态查找和异构互操作性以及跨平台互操作性。最后对前面所做的工作做出总结并对下一步将完善的工作进行准备。 手机服务系统是当前移动应用的研究热点,它促进了移动服务系统的开发和应用,其影响深远,同时也给Web Services技术在手机系统的应用开辟了广阔的空间。结果证明本文提出的服务系统是有效的、可行的、成功的。更多还原

【Abstract】 Mobile web service is an application of the technology of web service on the mobile device, and it has become a significant trend on mobile system design. Now there are a few mobile systems, but these systems are not perfect. In this paper, the important aspect of mobile service system is studied.As one of the three major platforms of Java, J2ME is targeted to resource-constrained devices like mobile phones and personal digital assistants. Web Service allows just-in-time integration of applications, and provides applications high extensibility. For their advantages, J2ME and Web Services are adopted in the research and development work of mobile service systems.In this paper, the author develops the projects base on the Web Services. It mainly includes the following contents: (1)J2ME technology, mainly about its architecture. (2)Web Services technology and how it is used on the server. (3)Taking the Mobile Service System for an example, explains the main aspects in mobile application development, including: ①the model of the phone service system based on web services.②the structure and working principle of the service system implementing.③the flow charts of sub-services in the service system. (4)Explains in detail the implementation of the Mobile Service System. It introduces the development, issue of sub-services and the client’s development. The system’s ascendency manifests some aspects: dynamic research, isomerous mutual-work and multiplatform. At last, the current development work is summarized, and some suggestions for later development are offered.Phone Service System is the research hotspot of current mobile application, and it is not only far-reaching, but also developing vast space for Web Services science in the application of phone system. The result is proved that the mobile service system is effective, successful and feasible.更多还原
