Web Applications Development Using J2EE Architecture

Abstract

Through Internet, it is more complex to develop Web-based application including all various ways of business logic on World Wide Web. It is important that development time and economy cost are key values of customer application to the enterprise. We will explain the advantage about J2EE, and show how to use J2EE’s architecture to build complex Web applications. Step by step, we bring up probable Web architectures including a flow for designing enterprise Web-based applications. We introduce J2EE’s Enterprise Java components including Servlet, JSP, and enterprise beans and comply J2EE’ blueprints to construct not only simply but also strongly functional dynamic pages contained dynamic content which would be deployed inside the presentation tier of Web applications and build reusable, manageable, maintainable, and high-performance enterprise business objects which would be deployed inside the middle-tier of its Web applications. And the UML that published by OMG noncommercial organization is most populating model language. So in this paper, we describe our system by UML. We propose building business objects with EJB-compliant to encapsulate business logic with synchronous and asynchronous operations. Enterprise business is multifaceted, but it always encompasses e-commerce (B2C) and business-to-business solution. So we implement and illustrate a simply Web-Store containing B2C and B2B which will be applied our technique and J2EE’s technology.
