| More and more mobile telephone and other wireless device take part in our work and our life. At the same time, it is imperative that mobile telephone and other wireless link with the network. There are many disadvantages in the software of conventional mobile telephone. On the other hand, the advantage of Java technology in wireless network service is very obvious.This scheme was founded just when Sun MicroSystems released Mobile Information Device Profile. When this scheme began to be put up, it is in the highest flight in China. Based on J2ME, the scheme integrates the serial technology of Java (J2ME, J2SE, servlet and JSP of J2EE), and composes a powerful and pure Java software system. It unites the innovative idea of the software of Java Mobile Telephone Base on J2ME and the rising vocation in China (football lottery vocation), and makes the last technology contribute to the last vocation.This scheme implements the whole system by module, basing on the rule of publishing and running football lottery, with focus on football lottery database, and from the point of view of manager and normal user.This paper introduces the Software of Java Mobile Telephone Base on J2ME -Chipping In System of Football Lottery in Mobile Telephone perfectly and clearly. The paper consists of its theory value and practicality value, process of designing and implementing, the key technology it has used. It enters principally into following content:CD Bring forward the whole architecture of the system. Basing on the design target and the rule of running football lottery, the paper brings forward the whole design blueprint, and enters into the problem needing solve and the key technology used.(2) Design the football lottery database. Basing on the restriction of database design and the reality of running football lottery, it sets up the football lottery database running on SQL Server 2000.(3) Design and implement the background maintenance system. The background maintenance system is bases on B/S structure, and the manager may handle the data of football lottery anywhere he can log in the web site of football lottery. The background maintenance system is separated into maintenance module of user information, team information, match information, score information. In these modules, some special technology is used, such as JavaBean, connection pool of database, and MVC mode.(D Implement MIDP client of the system. MIDP client is the exclusive device for chipping in football league matches. Its chief function involves managing local user, handling local data, chipping in, querying the integral of the league matches, querying record what users chip in, and querying win record. It uses much technology , such as servlet, connection pool of database, persistent storage of J2ME, and network characteristic of J2ME.For the restriction of research condition, this system is simulative. But it still has practical instruction and application value. |
