基于j2ee的公交查询系统的设计与实现论文设计

外文文献ABSTRACT: By studying the characteristics of mobile e-commerce platform based on J2ME-J2EE, this paper puts forward a complete solution of mobile query system, analyses the design schemes of mobile client and server in detail, and analyses and designs the architecture of mobile bus query system, the implementation of J2ME client, the implementation of server and the connection of database with JDBC. Key words: J2ME; J2EE; Mobile E-commerce1 IntroductionThe JavaTM 2 Platform, Enterprise Edition (J2EETM) is a popular multi-tier enterprise application technology. One of its advantages is that it can adapt to different types of clients, such as Web browsers, Java Applets and Java applications. Clients can be easily deployed on laptops, desktops and workstations to achieve cross-platform. J2METM (The JavaTM 2 Platform, Micro Edition) is currently the most widely used mobile device-based development technology. It provides a new type of enterprise client, such as mobile phone, PDA and other handheld devices. J2ME is built on MIDP (Mobile Information Device Profile) and CDC (Connected Limited Device Configuration) or CDC (Connected Device Configuration). MIDP is a series of Java APIs constructed by device manufacturers according to their needs. Different mobile device manufacturers can construct different APIs according to different needs to meet the needs of device development. CLDC or CDC are Java APIs that must be supported by all mobile devices provided by Sun. Therefore, one of the difficulties in mobile device development is how to develop a universal program. Combined with J2ME and J2EE technology, users can build a complete mobile e-commerce platform. Mobile Commerce (M-Commerce) is the application of...
