Developing Car Saling System By J2EE Technology

Today, more ande more developer want to write distributed transactionalapplications for enterprise and thereby leverage the speed ,security and reliability ofserver-sid technology.Enterprise system includes distributing, scaling andmulti-customer business system. These systems essentially shall improve the productefficiency by information technology. This article discuss J2EE technology and theprocess which use J2EE to develop scalable, security and web function enterprisesystem. Since J2EE is big and complex, this article tries to introduce the developmethod and programming technique by constructing a web car-saling on linesystem.In the process of development, we use the software thinking method whichinclude the requirement analysis,general design and detail design, test and so on. Weuse the rational rose to capture the requirement, Jbuilder as well as Weblogic toconstruct the system. For the sake of using J2EE technique, the system is robust,platform-indepent and easy to integrate with existing system and could serve thecustomer all day long.The first part of this article will introduce you the meaning of this project andsome of the reference technologies. The following parts are order by the software'sdevelopment procedure: requirement analysis, conceptual design, coding, testing anddeployment. In this article, we emphasize applying the technology of EnterpriseJavaBeans, a kind of component-based development technology on J2EE platform.Some examples are also given there.
