摘  要
過去的幾年，電子商務(wù)的迅猛發(fā)展為企業(yè)創(chuàng)造了極大的價值，使傳統(tǒng)的企業(yè)商務(wù)模式發(fā)生了很大的改變。隨著手機使用的普及和無線技術(shù)的發(fā)展，移動電子商務(wù)將會作為電子商務(wù)領(lǐng)域中的一種新型的電子商務(wù)模式，其發(fā)展前景是十分誘人的。可以預(yù)見的是，移動電子商務(wù)將成為21世紀電子商務(wù)領(lǐng)域的主戰(zhàn)場。J2ME是為嵌入式消費電子設(shè)備提供的JAVA語言開發(fā)平臺，是針對資源受限設(shè)備。因此基于J2ME平臺的無線終端的應(yīng)用程序開發(fā)以及與網(wǎng)絡(luò)服務(wù)器端的信息交互開發(fā)就十分重要。利用客戶端 + Java servlet + SQL Server數(shù)據(jù)庫三層模式實現(xiàn)網(wǎng)上商店系統(tǒng)是通用的方法。所有的業(yè)務(wù)邏輯都封裝在servlet中，數(shù)據(jù)庫的使用提高了數(shù)據(jù)的安全性，而采用可擴展標識語言XML的數(shù)據(jù)格式實現(xiàn)了跨平臺的數(shù)據(jù)交換。詳細闡述了系統(tǒng)的需求分析、系統(tǒng)總體架構(gòu)及詳細設(shè)計，系統(tǒng)實現(xiàn)了以下功能：會員注冊、登錄、瀏覽物品詳細信息和購買物品。

The Palm Platform of e-Shop Based on the J2ME－Server Development
Abstract
Over the years, the fast fierce development of electronic commerce created tremendous value for the enterprise, which greatly changed traditional enterprise commerce pattern. With the preva lence of mobile phone and development of wireless, Mobile e-commerce will be a new e-commerce mode in the electronic commerce realm, and it is very promising. It can be predicted that the mobile e-commerce will become the major industry of e-commerce in the 21st century. J2ME is the platform that provides the JAVA language to develop the embedded electronic equipment of expense, which aims at the equipment that resource is limited. Therefore the interactive information exploitation developing with network server and applications of wireless terminal development based on J2ME platform is very important. It is a general method to implement the system of e-shop using three layers of pattern: client side + Java servlet + database of SQL Server. All the business logic encapsulated in the servlet, using of the database improved the security, and using the XML data format achieved cross-platform data exchange. To the system demand analysis, the system requirement analysis, the overall of system construction and the detailed design are elaborated in details in this paper, and the system achieves the following functions: Member registration, login, browse detailed information and purchase goods.

Key words: J2ME; XML; SERVLET; E-SHOP
