Operational Support System Of Wireless Dispenser

In this paper the Operational Support System of Wireless Dispenser is analyzed and implemented. It realizes 4 functions as configuration for the basic information of the system, monitor for the Wireless Dispenser and statistic for the information of trading, management of logistics of the goods, account-checking management systems of point-exchanging used in the system towards CICS interface and micro-payment, which are both for China mobile of Liaoning.Firstly, it is compared and analyzed in the paper among these schemes, CGI and ActiveX, and comes to conclusion that it is predominant for the system to adopt the scheme of J2EE multi-tier construction. Then, the thinking and main technology for designing the system is referred---OOP (Object Oriented Programming) thought and J2EE multi-tier construction, JSP, JDBC, JavaBeans, JavaScript, JAVA design patterns. Subsequently, the method that design and realize the 4 function-modules of the system, as it is called system configuration, monitor and query,- account-checking management and logistics management, by means of software engineering is stated. JDBC is encapsulated in JavaBeans, which in charge of handling the database data. These beans realized the business tier of J2EE. JSP is counted on to implement the result of displaying dynamic pages; JavaScript falls to implement the qualified restriction. They are the web tier of J2EE. In the designing of account-checking management, JAVA design patterns are turned to design the software that is used for micro-payment account checking. For the sake of the security of the management of the system, there are various privileges for various users to manage the system. And what's more, the Oracle9i database, which is the enterprise information system tier of J2EE, is backed up in the system.Finally, the process of the unit test and integrated test of the system are introduced at length, and the conclusion is drawn. After more than half year of applications, operational support system of wireless dispenser runs stable and reliable, and it has the good qualities of operation to be simple and maintenance to be convenient.
