摘 要
根據(jù)SUN的定義， J2ME是一種以廣泛消費性產(chǎn)品為目標的高度優(yōu)化的Java 運行時環(huán)境，它包括尋呼機、移動電話、可視電話、數(shù)字機頂盒和汽車導航系統(tǒng)。J2ME具有顯著的優(yōu)勢，它對移動設備的智能化和多樣化提供了革命性的解決方案，并因其具有“Write Once, run anywhere”的Java特性提高了開發(fā)效率。隨著移動通信市場競爭的逐漸加劇，移動通信運營商將逐步把戰(zhàn)略投資方向轉(zhuǎn)移到種類繁多的無線數(shù)據(jù)業(yè)務上面來，因此J2ME無線數(shù)據(jù)應用具有較為廣泛的商業(yè)前景。目前，網(wǎng)上購物系統(tǒng)具備的24×7服務模式與即時互動方式，大量吸引了廣大購物者的注意力，具有很大的市場潛力。
本論文選擇的是基于J2ME平臺來研究無線網(wǎng)絡模式下的網(wǎng)絡商店，論文首先介紹了J2ME相關的基礎技術與理論，隨后研究了在線銷售系統(tǒng)的若干關鍵技術，重點是對客戶端部分的結(jié)構(gòu)和具體功能做了較為詳細的闡述。最后，根據(jù)自己的設計思路和方法實現(xiàn)了基于J2ME平臺的掌上網(wǎng)絡商店客戶端系統(tǒng)的開發(fā)，并與負責服務端開發(fā)的同學進行了驗證、配合測試，達到了預期成果。

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.
