As a software architect or developer involved in industrial projects, you should understand and be able to utilize critical software sub-disciplines such as architecture, engineering analysis and design, process development, visual modeling, and the underlying technology to be successful. In particular, this book tries to answer the following key questions: What is UML and how it is relevant to J2EE development? How do Java and UML related to each other? Are the key concepts in software architecture? How do software development as the process into the equation J2EE software development? How does the analysis and design to help you in arriving at the J2EE application design is better? What are the key J2EE technologies, and how they fit together? How do you leverage the UML for J2EE development? To give practical illustrations of the topics covered, this book guides the reader through a sample J2EE application development project using the Rational Unified Process and UML. Current J2EE application developers will learn how to apply UML to J2EE application development. After reading the book, you will: Be able to effectively use the UML for developing J2EE applications Learn about the key J2EE technologies (EJB, JSP, Servlets) at the technical level. Model 2 architecture, and situations where patterns such as objects of value and session bean chaining may be appropriate Understanding the concepts of software architecture, such as decomposition, layering, components, frameworks, patterns, and levels Can apply techniques such as use case analysis, analysis object discovery, and analysis to design transformation to your J2EE project Understand the concept of software development process and the basics of several processes that are popular Learn how to start using the Rational Unified Process for your J2EE project This book only covers the Java language to the extent provided key concept mapping Java to UML.
