Using and Understanding Java Data Objects is an application programmer's guide to the Java Data Objects (JDO) specification recently accepted by the Java Community Process. JDO provides a universal and transactional persistence service for objects. JDO will store and retrieve objects of nearly any application defined class using any data storage technology for which a JDO implementation is available. JDO completely encapsulates the details of the underlying data storage technology that is used. JDO has its own query language (JDOQL) that allows the programmer to find objects based on the fields and relationships of the object model. The syntax of JDOQL is similar to the syntax of Java itself. JDO increases programming productivity by simplifying and minimizing the code that must be written to store and retrieve object state. The use of JDO also allows the application to be ported across different data storage technologies. Like the servlet and EJB specification, JDO is a standard that will be implemented by competing software vendors. Several JDO implementations are currently available as third party products for relational databases and object oriented databases. of JDO. Part I is a guide to the JDO API, the JDO metadata, and JDO's byte code enhancement. Part II explains the use of JDO in several application deployment scenarios, including stand-alone, client-server, servlet, and EJBs. Part III is a tutorial explaining the example programs and learning tools supplied with the book.

ASP.NET is a wonderful new enabling technology that allows developers to create business solutions much more effectively than ever before. However, there is room for improvement. Developers often do not see the potholes and pitfalls related to this technology until they stumble. "Real World ASP.NET Best Practices" helps readers to avoid just such frustrations. The book's in-depth coverage includes data handling, caching, JavaScript, user and server controls, distributed programming, configuration, and deployment.

"Real World ASP.NET Best Practices" goes far beyond the documentation to teach ASP.NET development best practices based on the authors' real-world experience. The book's emphasis is on helping developers perform tasks correctly and avoid mistakes, not on teaching ASP.NET in general.

Genetic algorithms provide a powerful range of methods for solving complex engineering search and optimization algorithms. Their power can also lead to difficulty for new researchers and students who wish to apply such evolution-based methods. "Applied Evolutionary Algorithms in Java" offers a practical, hands-on guide to applying such algorithms to engineering and scientific problems. The concepts are illustrated through clear examples, ranging from simple to more complex problems domains; all based on real-world industrial problems. Examples are taken from image processing, fuzzy-logic control systems, mobile robots, and telecommunication network optimization problems. The Java-based toolkit provides an easy-to-use and essential visual interface, with integrated graphing and analysis tools. Topics and features: *inclusion of a complete Java toolkit for exploring evolutionary algorithms *strong use of visualization techniques, to increase understanding *coverage of all major evolutionary algorithms in common usage *broad range of industrially based example applications *includes examples and an appendix based on fuzzy logic This book is intended for students, researchers, and professionals interested in using evolutionary algorithms in their work. No mathematics beyond basic algebra and Cartesian graphs methods are required, as the aim is to encourage applying the Java toolkit to develop the power of these techniques.

Learning a complex new language is no easy task especially when it s an object-oriented computer programming language like Java. You might think the problem is your brain. It seems to have a mind of its own, a mind that doesn't always want to take in the dry, technical stuff you're forced to study. The fact is your brain craves novelty. It's constantly searching, scanning, waiting for something unusual to happen. After all, that's the way it was built to help you stay alive. It takes all the routine, ordinary, dull stuff and filters it to the background so it won't interfere with your brain's real work--recording things that matter. How does your brain know what matters? It's like the creators of the Head First approach say, suppose you're out for a hike and a tiger jumps in front of you, what happens in your brain? Neurons fire. Emotions crank up. Chemicals surge. That's how your brain knows.And that's how your brain will learn Java. "Head First Java" combines puzzles, strong visuals, mysteries, and soul-searching interviews with famous Java objects to engage you in many different ways. It's fast, it's fun, and it's effective. And, despite its playful appearance, Head First Java is serious stuff: a complete introduction to object-oriented programming and Java. You'll learn everything from the fundamentals to advanced topics, including threads, network sockets, and distributed programming with RMI. And the new. second edition focuses on Java 5.0, the latest version of the Java language and development platform. Because Java 5.0 is a major update to the platform, with deep, code-level changes, even more careful study and implementation is required. So learning the Head First way is more important than ever. If you've read a Head First book, you know what to expect--a visually rich format designed for the way your brain works. If you haven't, you're in for a treat. You'll see why people say it's unlike any other Java book you've ever read.By exploiting how your brain works, "Head First Java" compresses the time it takes to learn and retain--complex information. Its unique approach not only shows you what you need to know about Java syntax, it teaches you to think like a Java programmer. If you want to be bored, buy some other book. But if you want to understand Java, this book's for you.

Design Patterns for Web Services in Java describes the architectural patterns that guide developers through design patterns (service implementation and usage) and illustrates different ways in which Web services can and will be used. Design Patterns for Web Services in Java is not the typical narrative tome. Instead, after some introductory text, author Paul Monday provides a catalog of approximately 20 patterns that are typically needed in the development of Web services-based systems.

XHTML is a flexible XML-based markup language for designing Web sites. In January 2000, the W3C announced that it was supporting the development of XHTML as a replacement to HTML. HTML will continue to be around for a while, but if you want to develop Web sites for the future you need to switch to XHTML. Designers who make the change find that they can develop faster, better sites using XHTML. Most Web sites are interactive, responding to the viewer. To do this you need to use a scripting language - JavaScript is the most popular scripting language and interfaces easily with XHTML. To develop powerful interactive Web sites you need to understand these technologies and how they work together. Essential XHTML fast gives you everything you need to develop great Web sites in XHTML, including an introduction to scripting with JavaScript so that you can create dynamic interactive Web pages. There are many step-by-step examples, which you can download from the series Web site. It covers key aspects such as: - The relationship between XML and XHTML - Cascading Style sheets for formatting layout - Using text, images and image maps as links- Creating and using tables - The new standard for frames - Interactive XHTML forms - The JavaScript language- Incorporating JavaScript into XHTML pages- Handling events in JavaScript The source code for the examples in this book is available at the Essential series web site http://www.essential-series.com

Smart web developers will tell you that the sooner you detect your code mistakes, the quicker you can fix them, and the less the project will cost in the long run. Well, the most efficient way to detect your mistakes in PHP is with PHPUnit, an open source framework that automates unit testing by running a battery of tests as you go. The benefits of PHPUnit are significant, they are: a reduction in the effort required to frequently test code; fewer overall defects; added confidence in your code; and improved relations with your open source teammates. The only problem with this popular testing tool was its lack of documentation-until now, that is. For this, "O'Reilly" went right to the source, as Sebastian Bergmann, the author of "PHPUnit Pocket Guide", also happens to be PHPUnit's creator. This little book brings together hard-to-remember information, syntax, and rules for working with PHPUnit. It also delivers the insight and sage advice that can only come from the technology's creator. The coverage of testing under agile methodologies and Extreme Programming (XP) is also included. The latest in "O'Reilly's" series of handy Pocket Guides, this quick-reference book puts all the answers are right at your fingertips. It's an invaluable companion for anyone interested in testing the PHP code they write for web applications.

This volume describes the status of fractal imaging research and looks to future directions. It will be useful to researchers in the areas of fractal image compression, analysis, and synthesis, iterated function systems, and fractals in education. In particular it includes a vision for the future of these areas. It aims to provide an efficient means by which researchers can look back over the last decade at what has been achieved, and look forward towards second-generation fractal imaging. The articles in themselves are not meant to be detailed reviews or expositions, but to serve as signposts to the state of the art in their areas. What is important is what they mention and what tools and ideas are seen now to be relevant to the future. The contributors, a number of whom have been involved since the start, are active in fractal imaging, and provide a well-informed viewpoint on both the status and the future. Most were invited participants at a meeting on Fractals in Multimedia held at the IMA in January 2001. Some goals of the mini-symposium, shared with this volume, were to demonstrate that the fractal viewpoint leads to a broad collection of useful mathematical tools, common themes, new ways of looking at and thinking about existing algorithms and applications in multimedia, and to consider future developments. This book should be useful to commercial and university researchers in the rapidly evolving field of digital imaging, specifically, chief information officers, professors, software engineers, and graduate students in the mathematical sciences. While much of the content is quite technical, it contains pointers to the state-of-the-art and the future in fractal imaging.

Java developers have adapted to a world in which everything is an object, resources are reclaimed by a garbage collector, and multiple inheritance is replaced by interfaces. All of these things have prepared developers to thrive in Microsoft's new .NET environment using C#.

Despite similarities between Java and C#, complex differences still lurk. This book will walk you through both language and library differences, to help you develop enterprise applications requiring mastery. You will then be able to build applications that communicate with databases and include network components, web pages, and many other features.

Ordinarily, Java developers rely on Java 2 Enterprise Edition (J2EE) to provide these libraries, and C# developers rely on the .NET Framework. At first glance, there seems little similarity between the two, but author Paul Gibbons shows how a Java developer's J2EE skills transfer smoothly when tackling the .NET Framework.

Early chapters highlight C#'s differences from Java, and discuss differences between the .NET CLR and JVM. Subsequent chapters cover various technologies in which J2EE development translates into .NET enterprise development. These middle chapters also explain .NET technologies that Java developers can begin using immediately. The final chapter examines migration of existing Java applications to C#, and the available tools and techniques. By the end of ."NET Development for Java Programmers," a professional Java developer will be able to tackle a real software project in .NET, using C#.

"XML Programming: Web Applications and Web Services with JSP and ASP" provides a fast-moving introduction to the XML family of technologies for programmers. Although written with a focus upon JSP- and ASP-based XML solutions, the book presents the material from a language-independent point of view that benefits all developers, whatever their language. The code is written to be readable by all.

Chapters 1 through 3 cover the foundations of XML well-formed and valid documents, DTDs and namespacesbut XLink, XPointer, and elements of XSLT are introduced early so the examples can be interesting and useful. Chapters 4 through 6 cover XML processing using SAX, DOM, and XSLT, separately and in various combinations. Each chapter progresses from simple to advanced examples.

Chapter 7 is devoted to the development of a real world project involving the use of various XML technologies to create an information repository. In the context of the project, the authors present RDF and the Dublin Core; revisit XPath, XLink, and XPointer; and show how XML data can live inside a relational database. Chapter 8 introduces the newer validation technologies (RELAX NG and XML Schema), in preparation for the final chapter on Web services. In the concluding chapter, the authors not only explain the specifications, but also build working examples: You're shown, step-by-step, how to convert a software module into a Web service, how to generate a WSDL description from code, how to use WSDL to generate stubs and skeletons for distributed language-independent applications, and how to register such applications with a UDDI repository, either local or on the Internet.

"XML Programming: Web Applications and Web Services with JSP and ASP" is an indispensable resource for programmers who wish to become proficient in XML technologies and use them for solving large-scale, real-life problems.

This second edition of Foundations of Python Network Programming targets Python 2.5 through Python 2.7, the most popular production versions of the language. Python has made great strides since Apress released the first edition of this book back in the days of Python 2.3. The advances required new chapters to be written from the ground up, and others to be extensively revised. You will learn fundamentals like IP, TCP, DNS and SSL by using working Python programs; you will also be able to familiarize yourself with infrastructure components like memcached and message queues. You can also delve into network server designs, and compare threaded approaches with asynchronous event-based solutions. But the biggest change is this edition's expanded treatment of the web. The HTTP protocol is covered in extensive detail, with each feature accompanied by sample Python code. You can use your HTTP protocol expertise by studying an entire chapter on screen scraping and you can then test lxml and BeautifulSoup against a real-world web site. The chapter on web application programming now covers both the WSGI standard for component interoperability, as well as modern web frameworks like Django. Finally, all of the old favorites from the first edition are back: E-mail protocols like SMTP, POP, and IMAP get full treatment, as does XML-RPC. You can still learn how to code Python network programs using the Telnet and FTP protocols, but you are likely to appreciate the power of more modern alternatives like the paramiko SSH2 library. If you are a Python programmer who needs to learn the network, this is the book that you want by your side.

While most other books merely instruct on basic JSP and servlet development, "JSP Examples and Best Practices "gives you some of the best practices and design principles, enabling you to build scalable and extensible enterprise Java applications.
