The Implementation And Application Of The Special Database Custom Tag Based On JSP/SERVLET2.3 Norm

With Internet technology fast developing, the applications of the Web become more and more broadly. At the same time, the technology of java, which possesses the character of crossing platform, also achieves extensive development space. Since 1999 years, sun&co. J2EE platform as a sort of Web application's development standard and norm which had gotten extensive popularization and consummation. Meanwhile, the implementation framework based on J2EE platform also appears continually. This thesis expect that the study can come to the aim of improving the J2EE Web application's development efficiency through studying a sort of the implementation framework (Struts) and the technology of JSP custom tag developing database tag.This paper introduceed J2EE correlation knowledge including JSP, Custom Tag , Servlet, Java Bean and J2EE architecture etc. On J2EE architecture, the author mostly discussed the relation among of J2EE components (client tier component, Web tier component, business logic tier component, business information system tier) .On JSP and Custom Tag, the feature, development flow, class, implementation interface of the Custom tag were analysed. The system adopted database source to connect database and used JDBC to develop database program, and developed a set of independent database Custom Tag library through the technology of JDBC. The database tag can rapidly connect database, visit database form and return data set, at last show data in client's JSP pages.This thesis emphasised on discussing the implement of a suit of technology project, which used the database custom tag library fast to develop a system that had the function of member registering, user logging on, product management, shopping car management, order management, product dynamic release etc.
