When people view the J2EE (Java 2 Platform, Enterprise Edition) specifications, too often all they see is a “bag of APIs” without a way to understand how the specifications work together in an application server. In this tutorial we will examine some template architectures for successful J2EE systems and show how a common set of design patterns can be applied to help designers navigate through the J2EE problem space. We will examine common client-side pitfalls and discuss the pros and cons of different design options, discuss how Java Servlets and JavaServerPages (JSPs) can work with and within technologies like Apache Struts, XML, and Extensible Style Sheets (XSL), and discuss how EJB (Enterprise JavaBean) systems can be structured to maximize component reuse while reducing wasted programmer effort. Attendee Background: This tutorial is targeted to Java programmers and designers, with at least some exposure to J2EE technologies (a reading knowledge of the J2EE specification and the associated API specifications will be sufficient). Programmers who have had experience with one or more of the J2EE technologies will gain the most from this review of how all the technologies fit together and how problems are solved using the entire J2EE framework. Presenter: Kyle Brown is an Executive Java Architect with IBM’s WebSphere Services unit. He is an experienced presenter at OOPSLA and other industry conferences. He has over twelve years of experience with object-oriented systems, and has been specializing in Enterprise Java systems since 1997. He is a co-author of The Design Patterns Smalltalk Companion and Enterprise Java Programming with IBM WebSphere, both published by Addison Wesley Longman.
