摘 要
根据SUN的定义， J2ME是一种以广泛消费性产品为目标的高度优化的Java 运行时环境，它包括寻呼机、移动电话、可视电话、数字机顶盒和汽车导航系统。J2ME具有显著的优势，它对移动设备的智能化和多样化提供了革命性的解决方案，并因其具有“Write Once, run anywhere”的Java特性提高了开发效率。随着移动通信市场竞争的逐渐加剧，移动通信运营商将逐步把战略投资方向转移到种类繁多的无线数据业务上面来，因此J2ME无线数据应用具有较为广泛的商业前景。目前，网上购物系统具备的24×7服务模式与即时互动方式，大量吸引了广大购物者的注意力，具有很大的市场潜力。
本论文选择的是基于J2ME平台来研究无线网络模式下的网络商店，论文首先介绍了J2ME相关的基础技术与理论，随后研究了在线销售系统的若干关键技术，重点是对客户端部分的结构和具体功能做了较为详细的阐述。最后，根据自己的设计思路和方法实现了基于J2ME平台的掌上网络商店客户端系统的开发，并与负责服务端开发的同学进行了验证、配合测试，达到了预期成果。

The Palm Platform of e-Shop Based on the J2ME－
Client Development
Abstract
According to Sun’s definition, J2ME is an optimized Java functioning environment oriented in massive consumption products. And it includes: pagers, mobile phones, video phone, digital set-top boxes and car navigation systems. As a result, it provides a revolutionary solution for mobile devices and intelligent diversification, and improves the developing efficiency for its "Write Once, run anywhere "Java properties. Meanwhile, as the competition of mobile communications market increases, mobile communications operators will gradually shift the strategic direction of the investment business to a wide variety of wireless data services to their superiors, So J2ME wireless data applications with a wider range of business will prospect. Currently, online shopping system with a 24 x 7 service, which is an immediate interactive mode, not only attracts a lot of customers, but also has great market potential.
Based on that, this paper chooses J2ME-based network shop to study the wireless network model. At first, this paper introduces and analyzes the J2ME related basic technology and theory. And then it studies some key technologies of the online sales system. Still this paper surveys the details of the client part of the structural analysis and specific functions. Finally, according to the ideas and design method based on the J2ME platform for handheld shops network client system, and with the help of the classmate who was in charge of the server development, this paper achieves the expected results.
