Design And Implementation Of Mobile Forum

In recent years, internet technology has brought a revolutionary impact on the global economy; it also changes the understanding of people about the world. But, its influence is limited to the computer terminal. And the mobile Internet technology which uses mobile phone as the terminals has made up for its shortages. It extends the network to everyone's pocket and makes the network be truly ubiquitous, and brings more opportunities to the high-speed development network. So, extending the network to wireless network has become a hot point. The Mobile forum system based on J2ME and J2EE is built in this environment.Firstly, this paper analyzes the background of mobile Internet application, which introduces the gap in the field between our country and the overseas countries. Secondly, introduces the relevant background knowledge and comparison between different technologies. This paper designs a mobile forum system based on J2ME and J2EE which uses the advantages of J2ME and J2EE in the mobile application. Thirdly, basing on the above discussion and analysis of the characteristics of the system and considering the maintainability, scalability and practicality, determines that the system uses three-layer framework. That is mobile client layer, application layer and data storage layer. Finally, presents the designation and implementation of the key part of the system in each layer.A mobile forum system based on J2ME and J2EE is built in this paper, and it can provide several functions for users, such as online register, figure validate, personal information management, friends management, accessing forum, personal mail box, etc. With the functions of personal information management, it includes these modules: users' data, bulletin board and message board, etc. This system uses six degrees of separation theory to manage the users, and then users can divide their friends into different degrees, with this management, the six dimension relationship between current user and any other one can be easily seen. Beside the two above, when the user accesses the forum, he can appear a new topic with the tree structure, except this, he can also use the same theme style to browse the forum, open the interesting topic from the searching results by key words.This system based on J2ME and J2EE is great flexibility, interchangeable, compatible. According the result of this paper researched, many other systems can be built such as mobile professor system, mobile electronic commerce, mobile games online and so on.
