Wjth the development of web technology and ever increasing users’ requlre用ent, it beco珊es a trend for the course selection system through , which has no time and space restriction, to substitute the tradi tional course selection system with C/S with article first gives a brief introduction of object—oriented development platform J2EE,object modeling 1anguage U~tL and object—oriented unified software deVelopment process RUP as well as some core J2EE design a detailed introduction was given on the development process of a course selection system through based on J2EE with UML as model ing language and RUP as process framework: constructing requirement model through using use case diagrams and activi ty diagrams to make clear

users require珊ent and system boundary: constructing analysis model
through designing analysis classes,analysis sequence diagrams,analysis activity diagrams and some collaboration diagrams if necessary: constructing design model through designing design classes, sequence diagrams and class diagrams:constructing implementation model through the establi shment ponent diagrams and deployment l these four models reflect system’s characteristic from different aspects and they together add up to the integrity of the system. Taking account ponents’ reusability and flexibility,many kinds of design patterns have been extensiVely applied during the deVelopment process. In the end,a reliable and practical security policy,inⅣhich container
based declarative security is dominant and progra舢atic security i s
complementary, is given respectively to the web tier,EJB tier and EIS tier of the svstem according to the system framework and deployment environment. This article also supplies a good idea on how to develop a reusable and safe web appl ication quickly with object—oriented
