| The greate development changed with each passing day to the computer technique offer well base of the development of the distance education. This article, beginned with the development and the features of the distance education,proposes that distance education is distinct from the traditional education,having opening, elasticity, lifelong-study, community resource sharing. During the course of education there exist the instruction mould pattern,specific guidance pattern,discussion training pattern,probe pattern and coordination pattern and so on.At the same time, it shows the requirement and principle to put up the Distance Education and Teaching Management System(DETMS).All education activities of distince education should be considered about when designing and developing the DETMS,which DETMS should support.And then propose the rule that apply to the design and development of the DETMS as below.taking human as the essential factor .The rule of modularization standardization .the rule of Integration synthesisMultimode style support rule;The DETMS should be consising of hardware and software, and this article exhaustively introducs the function demand of it ,Point out that the roles which the system should be achieved are these: super media learning system of adaptiveness, multi-medium teaching system, tools of intercourse between teacher and student, management system of the network test question library, the examination and evaluation system, the managing system of education resource, answer and questions system, student studying and administration system, the network development system of courseware, the teaching management system, the fictitious laboratory based on web and so on.In the second section, now detailedly elaborates that the technique preponderance of J2EE lies in that be able to reserve available resources,can realize high efficiency of development, support defferent form of environment ,can be expanded and contranted quality and have steady usability,which is the foundation for the future upgrades and further development.Now describes the architecture of J2EE—client-layer module of client-side,web straturm module on J2EE server,logical layer module on J2EE's server and enterprise information system .The composition of J2EE is chiefly to explain the containers and the services in J2EE ,and it introduces the 13 kinds of core APIs module of J2EE .The following is the detail introduction to the JSP's mechanism, how employ JavaBean in JSP web page, characteristic of JavaBean ,the distinguish between JavaBean and EJB,the Servlet's high efficiency,convenient, powerful,a good transplant property and saving the investment. Afterwards carry on the fundamental step of using JDBC ,including loading the JDBC's driver,the definition connection of URL ,the establishment of connection,creating statement object,excuting query and updating database,handling the result set. As to how to choose the JDBC driver, the use JDBC connection pool Carrying on the batch updating database, the correct usage of result set and so on. All this optimizations are expatiated on this article.In the third section, it introduces the development environment of DETMS of Jilin University distince education of college,which is the technique of Apache+Resin+JSP+JavaBean,and meanwhile it also illustrates the installation process of Resin and Apache .Afterwards carries on the requirement analysis, and draws up the development scheme; currently the base of Jilin University DETMS is the Beijing Whaty system,and the reason for developing once again is that the old system dosen't suit for the need of the college's development,and its module must be upgraded and add new module roles into it.After that it points out that three design developing schemes have been compared ,and then chooses the third scheme which fits for most to present actual situation.The system supporting technique of distince education consist of the systematic pattern selection—choose B/S structure, and syst...
