| Along with Internet and enterprise counting in the development of the 90's, HTTP, HTML and Java' s platform develops becomes the standard of client calculation gradually. This has driven the development of concentrated commerce logic and the popularization of e-commerce in the server. At the server, the popularity of many kinds of program model of CGI etc has greatly increased the effort of programming and maintenance. The J2EK is the architectural structure that one kind of uti lization of Java2 that I.he Sun corporation introduced to simplify the complicated prob'.em that related to the development, deployment and management of many stages enterprise settlement scheme. The J2EE has provided the computation module and computational mode to develop and dispose the application of multilayer architectural, structure. By way of provides the question the essential various services of environment to it, and making to dispose, high reusability, safe nature, expandability and reliability can be realized in multilayer on the J2EE' s application. But develops based on the Web's application of J2EE, and still exists that the code structure is confusion.On the research of the design patterns, a frame structure of the Web' s application development of J2EE is proposed. Based on the Web's development of J2EE, multiple layer architecture has been usually used at the server. This frame uses the multitechnologys such as Jsp, Servlet, Taglib etc , and the presentation layer in the three layers of structure of model has been realized MVC' s model . Better having realized the application logic and code separates, and is easy to put in an important oosition of system maintenance and code. Debate the question thoroughly, finally has been in progress the certification to this frame, and gain expected effect by way of the living example.
