Two of the most significant technological development trends of the past few years have been the Java 2 Platform, Enterprise Edition (J2EE), a platform specifically geared to the needs of enterprise systems, and the Rational Unified Process (RUP), a comprehensive development methodology.Building J2EE™ Applications with the Rational Unified Process is the first book to bring these two key development concepts together. Featuring a non-trivial sample application, the book demonstrates a customized subset of RUP that is relevant and essential to J2EE development. The text guides readers through the entire development process, from initial requirements gathering through system implementation, illuminating real-world intricacies, complications, tradeoffs, and decision making.The book presents a review of the latest releases of J2EE and RUP, emphasizing the rationale behind their content. A developer roadmap helps readers navigate the development process successfully, and detailed discussions of each aspect of the process reveal practical strategies and techniques.Also provided is detailed coverage of the key aspects behind any successful software development effort:Requirements, including use-case modeling and the gathering of architecturally significant requirements Analysis, including the transformation of requirements into a first-cut design model and a user-experience model Design, including the refinement of a design model, introducing interfaces, framework components, design classes, and use-case realizations Implementation, including the creation of source code and executable code based on the design, and the production of J2EE modules necessary for deployment Architectural concerns, including the production of a Software Architecture Document, Deployment Model, and Data Model The use of patterns, in particular J2EE design patterns The use of UML to model J2EE technologies such as Enterprise JavaBeans™
