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™

Written for anyone working in J2EE or using RUP, this book is an comprehensive guide that reveals how J2EE and the Rational Unified Process come together to produce a powerful, efficient, and effective approach to enterprise application development.

Forewords were prepared by John Crupi, Distinguished Engineer at Sun Microsystems (and coauthor of Core J2EE Patterns, Prentice Hall, 2001), and Philippe Kruchten, Director of RUP Development at Rational Software (and author of The Rational Unified Process, Addison-Wesley, 2000).

Preface

About This Book

This book is about developing Java 2 Platform, Enterprise Edition (J2EE) applications with the Rational Unified Process (RUP) and the Unified Modeling Language (UML). There are a number of books describing the J2EE platform and its associated technologies. There are also books about software development processes and about RUP, in particular. However, we could not find a book that described and exemplified how to use a subset of RUP that contains only the most relevant parts of an otherwise large and comprehensive process, to build J2EE applications. The book bridges this gap between the RUP and J2EE technologies.

A world that combines J2EE, RUP and UML is complex. This world requires a good map if you are to successfully navigate your way through it. This book provides such a map both metaphorically and literally. It is metaphorical because the very objective of the book is to provide a description of a "safe path" through the J2EE application development activities. It is also literal because we define a "J2EE Developer Roadmap," which is a process map, to guide us. We describe the content of the book in more detail in Chapter 1, Introduction.

Who This Book Is For

While writing the book we kept three audiences in mind. The first audience is software architects, designers and developers familiar with the J2EE platform and its technologies, wanting to understand how to apply them in the context of a software development process. The second audience is development team members familiar with RUP, looking for help in applying the process to J2EE development. The third audience is software professionals who are neither familiar with J2EE nor with RUP, and are looking for an example of how to use RUP in the development of a J2EE application.

Conventions Used in This Book

The book is roughly divided into two parts. The first part, Chapters 2–5, summarizes the J2EE technologies, introduces RUP and the J2EE Developer Roadmap, and briefly describes our sample application. The rest of the book is what we refer to as the "process chapters" and contains a guided tour through a J2EE application development project.

We structured the process chapters to make them easy to read "at a glance," and to make it easy to refer to specific topics of interest. Each process chapter is organized primarily by activities. We provide diagrams that indicate the overall flow between the activities and the key artifacts that are consumed and produced by the activities. For each activity, we provide an overview table that summarizes the purpose of the activity, its input and output artifacts, and a summary of the steps performed within the activity. Following the table, we then describe the details of each of these steps, using the sample application.

In the process chapters, we use only one simple editing convention: we emphasize all references to process elements such as activities, steps, and artifacts.

Chapter 2

  • Page 9: Figure 2.2. The text "Applet" is missing from the box in the box labeled "Applet Container". The text "Application" in the box in the "Application Client Container" box should read "Application Client". See corrected PDF file on this site.
  • Page 18: Figure 2.8. The box in the "Client Device" box should contain the text "HTML Client". See corrected PDF file on this site.
  • Page 31: Figure 2.13. The unlabeled box in the box containing "Servlets" and "Java Classes" should be labeled "JSPs". The unlabeled graphic in the box containing "Java Classes" should be labeled "EJBs". See corrected PDF file on this site.

Chapter 3

  • Page 49: "RUP as a Process Framework" section: Remove bold-faced character format for the word "customization" since this is not a RUP process element. The text should still be italicized.

Chapter 4

  • Page 54: Figure 4.1. The text "defined in" between the Implementation Model and the Deployment Model should read "deployment defined in". See corrected PDF file on this site.
  • Page 55: 1st paragraph: last sentence: Change "...the physical files of the Implementation Model can be maintained using roundtrip engineering" to "...the physical files and directories can be maintained using roundtrip engineering".

Chapter 6

  • Page 74: Figure 6.4: The arrows should not have plain arrowheads, but should have open triangles as their heads. See corrected PDF file on this site.
  • Page 83: 3rd paragraph: 1st sentence: Change "documented in the Requirements Review of the Software Architecture Document" to "documented in the Software Architecture Document".
  • Page 88: 1st paragraph after the bulleted list: 2nd sentence: Change "on relationships between Use Cases, see the Structure the Use-Case Model activity" to "on relationships between Use Cases, see the Structure the Use-Case Model activity". In other words, bold the activity name.

Chapter 7

  • Page 127: Footnote 12. Second sentence. The text "The stereotypes are only used..." should read "The stereotypes and icons are only used...".
  • Chapter 8
  • Page 148: Figure 8.5. The line between client and FrontController should not be a solid line, but a dashed line with an arrowhead at the FrontController end. This line should also be labeled with "send request." See corrected PDF file on this site.
  • Page 150: Figure 8.7. The line between client and FrontController should not be a solid line, but a dashed line with an arrowhead at the FrontController end. This line should also be labeled with "send request." The BusinessEntity element should have the stereotype ‹‹EJBEntityBean›› and not ‹‹EJBSessionBean››. See corrected PDF file on this site.
  • Page 161: Figure 8.16. The AuctionEJB, BidEJB and CategoryEJB elements should all have the stereotype ‹‹EJBEntityBean›› and not ‹‹EJBSessionBean››. See corrected PDF file on this site.
  • Page 166: Figure 8.20. The stereotyped "use" between the PresentationRequestController and the CreateAuctionDispatcher should be removed. The stereotype ‹‹use›› should be placed next to the dashed line between AuctionManagerDelegate and AuctionManagerHomeLocator, and next to the dashed line between UserAccountManagerDelegate and UserAccountManagerHomeLocator. See corrected PDF file on this site.
  • Page 182: Third paragraph. Third sentence. The stereotype ‹‹interface realization›› should read ‹‹InterfaceRealization››.

Chapter 10

  • Page 231: Footnote 3. This should read "The Deployment Model shows the allocation of implementation elements to system nodes".

Appendix C

Add the following term and definition at their correct position in the Glossary:

Enterprise Component     A software implementation of a business concept or business process. It is a collection of related elements that should be a unit of design, implementation and deployment.
