J2ME 邮件修改.docVIP

摘 要 随着无线通信行业的迅速发展，硬件技术和无线通信网络GPRS和CDMA 1X的日趋成熟，手机的广泛应用，以及彩屏手机的普及，越来越多的人用手机来获取信息。通信公司2.5G和3G通信技术的发展，给手机用户带来了高达384KB/s的移动宽带，将语音、图像、视频有序的结合起来，给手机用户带来了更加丰富多彩的多媒体娱乐和商务服务，借此东风，各大公司都把销售平台往手机上移植。 手机邮件系统是在GPRS环境下，基于客户机/服务器应用方式，实现对邮件系统的管理。 本文从分析工程项目的可行性出发，结合现代化无线网络开发的基本要求，采用基于J2ME的开发技术，利用TOMCAT和Servlet技术设计了一个简单的邮件系统。Tomcat是Sun公司推荐的jsp和servlet的容器，其本身又具有服务器的功能。Servlet是Sun推出的一种动态网页的解决方案，它是基于java编程语言的web服务器端的编程技术，主要是在web服务器端获得客户端的访问请求信息和动态生成对客户端的响应信息。 论文首先从需求分析和概要设计对课题进行总体的设计，介绍了手机邮件的基本流程和主要功能。其次在编码的一章中对程序中用的关键技术的源代码进行了列举和说明。 最后介绍了系统的性能测试与相关运行结果。 关键词：J2ME，手机邮件，Servlet技术 Abstract With the rapid development of the wireless communications industry, the hardware technology and wireless communication network GPRS and CDMA 1X increasingly mature, widely used inmobile phones and the popularity of color mobile phones, more and more people using phones to access information.Communication 2.5G and 3G communication technologydevelopment, to mobile phone users, up to 384KB / s mobile broadband, voice, image, video and orderly combination of mobilephone users a richer multimedia entertainment and business services, take the wind, major companies regard the sales platform to the mobile phone transplantation. Phone mail system in a GPRS environment, based on client /server applications, the way the mail system management. From the analysis of the feasibility of the project, combined withthe basic requirements of modern wireless network development,J2ME-based development techniques, the use of TOMCAT andServlet technology to design a simple mail system. Jsp and servletcontainer, Tomcat is the Suns recommended its own serverfunctionality. Servlet is the Suns launch of a dynamic web solution, which is based on the java programming language, web server-side programming techniques, client access to the requestedinformation in the web server-side and dynamically generated onthe clients response. Firstly, the overall design from the needs analysis and outline design of the subject, describe
