Bug Patterns in Java presents a methodology for diagnosing and debugging computer programs. The act of debugging will be presented as an ideal application of the scientific method. Skill in this area is entirely independent of other programming skills, such as designing for extensibility and reuse. Nevertheless, it is seldom taught explicitly. Eric Allen lays out a theory of debugging, and how it relates to the rest of the development cycle. In particular, he stresses the critical role of unit testing in effective debugging. At the same time, he argues that testing and debugging, while often conflated, are properly considered to be distinct tasks. Upon laying this groundwork, Allen then discusses various "bug patterns" (recurring relationships between signaled errors and underlying bugs in a program) that occur frequently in computer programs. For each pattern, the book discusses how to identify them, how to treat them, and how to prevent them.

This book is about patterns for the Java 2 Platform, Enterprise Edition (J2EE). The J2EE patterns documented in this edition provide solutions for problems typically encountered by designers of software applications for the J2EE platform. All the patterns documented in the catalog have been discovered in the field, where they have been used to create successful J2EE applications for our customers. This book describes proven solutions for the J2EE platform with a particular emphasis on such key J2EE technologies as: JavaServer Pages (JSP), servlets, Enterprise JavaBeans (EJB) components, Java Message Service (JMS), JDBC, and Java Naming and Directory Interface (JNDI). We offer solutions for recurring problems for the J2EE platform through the J2EE Pattern Catalog and J2EE refactorings. You can apply these ideas when developing new systems or when improving the design of existing systems. The patterns in this book will help you quickly gain the proficiency and skills to build robust, efficient enterprise applications.

This book is an introduction to computer programming using the Java programming language. No prior knowledge of computers or programming is assumed, but the reader must be confident with high school algebra. This book does not claim to completely cover either the Java language or its standard libraries. We have confined the use of the static keyword to testing classes and enumeration classes, to help students avoid non-object-oriented programming, and we have omitted coverage of Java’s features for reflection, packages, multithreading, networking, applets, and graphical user interfaces. Instead, our emphasis is placed on writing programs of high quality using the best techniques, with extensive coverage of design, collection classes, code cliches, verification, testing, general software engineering, scalability, ethics, and recursion (including an application to recursive descent parsing). This book is divided into two parts. At the University of Sydney, each part serves as the text for one semester. We have delayed introducing inheritance to second semester, not because we think it cannot be mastered earlier, but because novice programmers have a lot to learn, and since inheritance can be deferred, we think it should be.

The authors pay special attention to testing, optimizing and debugging within WebLogic, to implementing security features, and to administering WebLogic applications.

In JavaServer Faces, developers learn how to use the new JavaServer Faces framework to build real-world web applications. The book contains everything you'll need: how to construct the HTML on the front end; how to create the user interface components that connect the front end to your business objects; how to write a back-end that's JSF-friendly; and how to create the deployment descriptors that tie everything together. This book is a complete guide to the crucial new JSF technology.

JavaServer Pages, Third Edition is completely revised and updated to cover the substantial changes in the 2.0 version of the JSP specification. It also includes detailed coverage of the major revisions to the JSP Standard Tag Library (JSTL) specification. Combining plenty of practical advice with detailed coverage of JSP syntax and features and clear, useful examples, JavaServer Pages, Third Edition demonstrates how to embed server-side Java into Web pages, while also covering important topics such as JavaBeans, Enterprise JavaBeans (EJB), and JDBC database access.

In the tradition of Effective Java™, Bloch and Gafter dive deep into the subtleties of the Java programming language and its core libraries. Illustrated with visually stunning optical illusions, Java™ Puzzlers features 95 diabolical puzzles that educate and entertain. Anyone with a working knowledge of Java will understand the puzzles, but even the most seasoned veteran will find them challenging.

If you already have experience programming games with Java, this book is for you. David Brackeen, along with co-authors Bret Barker and Lawrence Vanhelsuwe, show you how to make fast, full-screen action games such as side scrollers and 3D shooters. Key features covered in this book include Java 2 game programming techniques, including latest 2D graphics and sound technologies, 3D graphics and scene management, path-finding and artificial intelligence, collision detection, game scripting using BeanShell, and multi-player game engine creation.

Beyond covering JSP and Servlet APIs, this book shows you how to choose and implement the best persistence option for your web applications, how to secure web sites, improve the performance and scalability of your JSP pages, and much more.

The Eclipse Modeling Framework unifies Java(TM), XML, and UML-enabling developers to rapidly construct robust applications based on surprisingly simple models. In this book, leading EMF implementers illuminate every facet of using EMF for both modeling and code generation. Discover how EMF makes modeling easy and practical enough for virtually any Java project-and why EMF modeling provides a solid foundation for fine-grained interoperability and data sharing across multiple tools and applications.

Brimming with over 100 "recipes" for getting down to business and actually doing XP, the Java Extreme Programming Cookbook doesn't try to "sell" you on XP; it succinctly documents the most important features of popular open source tools for XP in Java-- including Ant, Junit, HttpUnit, Cactus, Tomcat, XDoclet-- and then digs right in, providing recipes for implementing the tools in real-world environments.

Combining the two key types of Java programming, Garg (Electrical and Computer Engineering Department, University of Texas) offers both professionals and students a guide to fundamental concepts necessary for mastering Java programming. Early chapters deal with techniques for programming in shared-memory based systems and cover concepts in Java such as threads and synchronized methods. Later chapters look at programming in a message-passing system, covering resource allocation problems, logical clocks, global property detection, leader election, and message ordering and logging. Treatment avoids excessive mathematical notation while explaining important concepts. Chapter problems are included. The book is copublished with IEEE Press.

Еще до появления XML существовала Объектная Модель Документа, Document Object Model или DOM. Она позволяет разработчику обращаться к компонентам в XML-структуре, выбирать и изменять их и является важной для работы с XML. В этом учебнике вы узнаете о структуре документа DOM. Вы также узнаете о том, как использовать технологию Java для создания объекта Document из XML_файла, изменения его и выборки результатов.

В этом учебнике исследуется Simple API for XML версии 2.0.x или SAX 2.0.x. Он предназначен для разработчиков, которые понимают XML и хотят изучить этот легкий событийно-базированный API для работы с XML-данными. Предполагается, что вы знакомы с такими концепциями, как правильное форматирование и с теговой природой XML-документа. (Вы можете получит базовые представления о самом XML из учебника Введение в XML.) В этом учебнике вы узнаете, как использовать SAX, чтобы выбирать, манипулировать и выводить XML-данные. Предварительные замечания: SAX доступен во многих языках программирования, таких, как Java, Perl, C++ и Python. Этот учебник использует для демонстраций язык Java, но концепции в разных языках, по существу, одинаковы, и вы можете получить понимание SAX, даже не работая на самом деле с этими примерами.
