【摘要】 随着信息技术的飞速发展，互联网已经成为人们生活的一部分。在互联网上开展各种服务已经成为许多企业和部门的急切需求。目前，基于Web的应用服务方式已经成为互联网服务的主流，无论是在国外还是国内，从传统行业到新型的电子商务，基于Web技术的应用极大地改变着传统的服务模式。在2000年初，SUN公司发布了Java 2 PlatformEnterprise Edition(J2EE)平台规范，提供了一种在企业级规模下的统一程序设计模式——基于Web的企业应用设计模式。 J2EE是一种利用Java 2平台来简化企业解决方案的开发、部署和管理相关的复杂问题的体系结构。J2EE技术的基础就是核心Java平台或Java 2平台的标准版，J2EE体系结构提供中间层集成框架来满足企业应用开发的需求。本文重点讨论了基于Web的多层体系结构，以及J2EE的实现技术。 随着移动通信市场的迅猛发展，其竞争也越来越激烈。为了提高ARPU值(AverageRevenue Per User，即对每个用户的平均收益)，各移动运营商纷纷致力于提供更多的增值服务，以此来诱导用户消费。因此，新建移动增值业务管理平台，将增值服务更好地提供给用户，加强对增值服务提供商(SP)的管理职能，成为迫切需要。本文根据J2EE规范，采用多层体系结构，给出了移动增值业务平台的数据库具体设计，服务层、表示层的详细设计和一些实现技巧。更多还原

【Abstract】 With the information technology development at very fast speed, internet has become a important part of people’s lives. It is urgent for many companies and departments to provide service by internet. At present, the way of service based on Web has become very popular. Whether in out land or in homeland, from tradition industry to new electronical business, the application based on Web technology greatly changed traditional service way. In the early 2000, the SUN ,a famous company, issued J2EE(Java 2 Platform Enterprise Edition). Which provides a unified design program mode under the enterprise scale. That is a enterprise application design mode based on Web.J2EE is a system which uses Java 2 platform to simplify development,deploying and management complex problem of enterprise settling project. The foundation of the J2EE technology is the core of the Java 2 platform or the standard version of Java 2 platform. The system of J2EE provides the framwork of integration middleware to meet the development of enterprise application. This paper primarily discusses the system of many layers based on Web, and the implementation technology of J2EE.With the mobile communication market rapid development, the completition becomes more and more sever. In order to improve the ARPU(Average Revenue Per User), each provider of mobile communication offeres more service of increment revenue to induce consumers. In order to offer better service and improve the manage of SP(service provider), it is urgent to build a new platform of mobile communication increment revenue. According to J2EE standard, the paper provides the specific design and implementation of the data base,server layer and expressing layer of the mobile communication increment revnue platform.更多还原
