Research On Developing Mobile Web Service In J2ME

I have engaged in J2ME technology research for half and one year, during which I participated in the development of J2ME network game project, and meanwhile, I also made some corresponding researches, aiming at JSP and extensible Markup Language. Combining the development practice, I have designed and realized a frame of Mobile Web Service. Mobile Web Service is a brand-new access method, which can let people use wireless telecommunication equipments such as cellular telephone, PDA assistant to access internet. Through the service, users can enjoy high-speed wireless data transmission. The series of network application services includes all kinds of news on Internet, games on line, various online businesses of banks and so on. My research is concentrated mainly on the following aspects:Firstly, I explain in detail the operating principles of two key technologies: J2ME and extensible Markup Language, which are needed in developing Mobile Web Service.Secondly, I analyze the main programming thoughts that MIDP network program design, J2ME and extensible Markup Language are combined, utilizing my own development instance.Thirdly, the paper is shown how to realize the client of Mobile Web Service, which includes the following work.1. First of all, I put forward an integrated solution for Mobile Web Service which includes the structure frames of server and client.2. It realizes quintet game function in moving network services.3. It realizes news-examining function in Mobile Web Service. The procedure of this paper involves 67 classes of J2MEs and kXMls, 17 files, about 5000 lines of codes.Fourthly, I analyze in depth two key technologies of Mobile Web Service: wireless network conversation and security of wireless communication. As to the former, I design a solution which is exercised in extensible Markup Language technology and realizes the whole process. As to the latter, I explain several possible solutions, however, the realization of these solutions needs a further study.The structure of this paper is as follows: In chapter one, I introduce the basic conception and system structure of J2ME, and its advantages and disadvantages. In chapter two, I explain the basic conception and main functions of extensible Markup Language, and the application advantages in Mobile Web Service. In chapter three, I explain the development principle of MIDP network procedure, utilizing my development instance. In chapter four, I introduce the great advantage of combining and applying Java and extensible Markup Language, and put forward the solution for Mobile Web Service of J2ME + XML. In chapter five which is the emphasis of the paper, I explain in detail the operating principle and realization process of Mobile Web Service. In chapter six, I analyze in depth two key technologies of the services, wireless network conversation and security of wireless communication. In chapter seven, I summarize the whole paper.
