Research On The Application Of Core J2EE Technologies In E-commerce

With the increasing popularization and extensive application of E-commerce, the traditional enterprise development platform is now facing flinty chanllenges. Because of the complex internal logic of E-commerce, the rigorous security demand and the quick changes of the commercial form, the development platform should provide enough complexity and flexibility to adapt the demand of E-commerce. In order to adapt this kind of demand, J2EE appears and makes itself perfect step by step. J2EE is a kind of architecture which is proposed by Sun Corporation in order to simplify the development and the deployment of the enterprise solution and manage related complex questions by using Java 2 platform. J2EE has provided the good mechanism in the way of building the expandable, flexible and easily maintained E-commerce platform.Firstly, the paper reviews the development course of enterprise application architecture. It discusses and compares the traits of three different kinds of enterprise application architecture. And then the paper carries on the analysis to J2EE platform from several aspects such as the hiberarchy, the application module, the structure, the superiority, the core technologies and the developmental direction. The paper also thoroughly discusses EJB which is the core technology of J2EE platform. Then this paper takes "B2B E-commerce platform" as a background and discusses in detail the analysis, the design, the actual development as well as the deployment of the project which is carried on under J2EE architecture. At last, the paper dissertates the key technologies of the system realization combining the concrete problem in the course of the development.Chapterl, introduction, discusses the background and the research meaning of the project.Chapter2, brief description of enterprise application architecture, focuses on three different types of enterprise application architecture and shows that the multi-tier distributed application architecture is the preferred one when buildingenterprise application platform.Chapter3, J2EE platform, focused on the hiberarchy, application component, structure, superiority, the core technologies and the developmental direction of J2EE platform.Chapter4, EJB technology, focuses on EJB which is the core technology of J2EE platform.Chapter5, system analysis and structure design, mainly introduces the demand of B2B E-commerce platform system, the function module and the network design and focuses on the analysis of the system by using 00 method and UML.Chapter6, development and deployment of the system, focuses on the component development and deployment of the system under J2EE architecture.Chapter7, key technologies of system realization.Chapter8, summarize of research work, mainly summarizes the development of the system, points out the defects, and describes the improved way of the system.
