摘 要
本次畢業(yè)設(shè)計設(shè)計并實現(xiàn)了一個移動Web服務(wù)的框架,所謂移動Web服務(wù),是一種讓人們使用移動電話、PDA等無線通訊設(shè)備接入Internet的全新接入方式,通過這類服務(wù)的用戶可以享受到高速的無線傳輸,包括Internet上的各類新聞、在線游戲、銀行各種網(wǎng)上業(yè)務(wù)等一系列網(wǎng)絡(luò)應(yīng)用服務(wù)。本文的工作主要集中在:
詳細闡述開發(fā)移動Web服務(wù)所需要的兩種關(guān)鍵技術(shù)(J2ME和HTTP)的工作原理。
利用自己的開發(fā)實例分析了移動Web服務(wù)的主要編程思想,即MIDP(Mobile Information Device Profile)網(wǎng)絡(luò)程序設(shè)計,以及J2ME(Java 2 Platform Micro Edition)技術(shù)與HTTP (Hypertext Transfer Protocol,超文本傳輸協(xié)議)技術(shù)的結(jié)合。
本文具體展示了作者如何實現(xiàn)移動Web服務(wù)的客戶端,其中包含以下工作:首先,提出了一個完整的移動Web服務(wù)的解決方案,包括客戶端與服務(wù)器的結(jié)構(gòu)框架;其次,實現(xiàn)了移動Web服務(wù)中的查詢繳費清單的功能。本論文程序涉及9個J2ME類和一個Servlet類。
關(guān)鍵詞:J2ME,HTTP,移動Web服務(wù)
The design and the realization of fee search up based on the J2ME’s technical cellular phone
Abstract
This project has designed and realized a frame of a Mobile Web Service. Mobile Service is a brand-new access method, and it can let people use wireless telecommunication equipments such as cellular telephone, PDA to access the Internet. Through the services, user can enjoy high-speed wireless data transmission. The series of network application services includes news on the Internet, games on line, online banks and so on. My research is concentrated mainly on the following aspects.
First, the project discusses in detail the operating principles of two key technologies: J2ME and HTTP, which are needed in developing Mobile Web Service.
Then, it analyzes the main programming principles that MIDP network program design, J2ME and HTTP are combined, utilizing my own development instance.
Third, it discusses how to realize the client of Mobile Web Service, which includes the following work.
This project puts forward an integrated solution for Mobile Web Service which includes the structure frames of server and client.
It realizes the function of the inquiry to pay expense in Mobile Web Service. The procedure of this paper involves nine classes of J2MEs and Servlet.
Key words:J2ME,HTTP,Mobile Web Service
