基于J2ME的校园即时查询系统

为填补校园信息在移动设备中的访问空缺, 设计了基于J2ME(Java Platform Micro Edition)的校园信息即时查询系统。该系统采用手机平台上流行的J2ME和J2ME Polish技术, 使客户端可以适应多种移动操作系统平台; 采用GSM (Global System for Mobile Communication) Modem硬件设备、多线程技术、模组化的设计结构、半同步/半异步模式, 使系统升级平滑, 便于新功能的加入和系统维护, 并有效解决了服务器与客户端交互和短信息交互模式双向信息提供问题; 从而实现了高效、方便、快捷的校园信息查询、 传播平台。测试结果验证了系统的可用性、 可靠性和安全性。

Study on Campus Real-Time Inquiry System Based on J2ME

In order to fill the vacancy of accessing campus information on mobile devices, a campus information inquiry system is designed and implemented. The mobile client applies popular J2ME Java (Plalform Micro Edition) MIDP and J2ME Polish framework to adapt a variety of mobile operating systems. GSM (Global System for Mobile Communication) Modem hardware, modular architecture and half-synchronous/half-asynchronous framework are applied to the server implementation to provide smooth update, ensuring the fairness and reliability of services on the server side, to give a solution on the interaction between the server and clients and a way of implementing queries through GSM messages. The benchmark results verify the availability, reliability and security of the system.
