Research And Application Of Based On J2ME Technology Handset Software

Nowadays the domestic single soccer lottery ticket has been distributed in three provinces and cities for only two years, but it develops very rapidly and the total sales actually rise steadily. Taking this into consideration, Guangdong CMCC builds the jot handset payment platform to be paid for single field soccer lottery ticket by using SMS. However the large quantity ticket is the main part of sales in the single soccer lottery ticket sales, and the present handset concentrates pattern certainly cannot solve how to purchase the large quantity ticket. In order to solve this problem, it needs to develop the mobile software second time, because the traditional mobile software was set by the handset manufacturer when the handset was manufactured. Nowadays J2ME is the main technology to develop the handset software second time.This paper has conducted the research to the handset software development, using J2ME to design and develop the single soccer lottery ticket handset concentrates system which the user can use handset to concentrate directly. The system stressed to solve the problem of the large quantity ticket, the user account secure and the realization of automatically exchanges the bonus. It has finished the functions that the user can purchase single soccer lottery ticket real-time by the handset, inquiry the concentrated records, inquiry all the winning tickets, and the server could exchange the winning bonus automatically to the use's bank account.The single soccer lottery ticket handset concentrates system is composed by the handset client terminal, the system server and the system database. The handset client terminal enables the user to fill his information, to inquiry competition schedule, to concentrate, to inquiry concentrated records and to inquiry the winning ticket and so on. Considered to operate simple, the operating speed and the storage capacity of the handset, the design of client terminal reduced the operand and the space. The server connects to the handset client terminal and the database, receives different kinds of request information, transmits data, accesses the database and returns the result. Simultaneously it also can concentrate users' individual information and their tickets, send winning announcement, calculate bonus, and deposit jot bonus automatically into the winners' bank account. The database centralizes users' information, competition information and all the concentrates records so that it can manage and backup them easily.The system uses J2ME to develop the handset client terminal, the MVC pattern to design the server, the network characteristic of J2ME to realize the communication between the handset client terminal and the server, the Servlet technology to process the messages from the client terminal to the server, to transmit data, and to return the results, JDBC to realize the connection between the server and the database and MySQL to design and develop the database.The system emphasizes the research of purchasing large quantity ticket of the single soccer lottery ticket directly by handset. It ties up the user account and the user bank information, adopts the method which drew money from the user bank account to carry on concentrates, so that it solves the large quantity concentrated problem. In order to guarantee the user bank information processes security in the transmission, the system has conducted the secure research to user's bank information. The way of tied up the information reduces the transmission times greatest, simultaneously carries on the encryption to the user bank information, has guaranteed the data transmission security. The system also realizes to send winning announcement, calculate bonus, and deposit jot bonus automatically into the winners' bank account.This paper introduced the system overall structure, the handset client terminal design, the large quantity concentrated function, the system server function and the system database design in detail.
