All of Java's Input/Output (I/O) facilities are based on streams, which provide simple ways to read and write data of different types. Java provides many different kinds of streams, each with its own application. The universe of streams is divided into four large categories: input streams and output streams, for reading and writing binary data; and readers and writers, for reading and writing textual (character) data. You're almost certainly familiar with the basic kinds of streams--but did you know that there's a CipherInputStream for reading encrypted data? And a ZipOutputStream for automatically compressing data? Do you know how to use buffered streams effectively to make your I/O operations more efficient? Java I/O, 2nd Edition has been updated for Java 5.0 APIs and tells you all you ever need to know about streams--and probably more. A discussion of I/O wouldn't be complete without treatment of character sets and formatting. Java supports the Unicode standard, which provides definitions for the character sets of most written languages. Consequently, Java is the first programming language that lets you do I/O in virtually any language. Java also provides a sophisticated model for formatting textual and numeric data. Java I/O, 2nd Edition shows you how to control number formatting, use characters aside from the standard (but outdated) ASCII character set, and get a head start on writing truly multilingual software. Java I/O, 2nd Edition includes: * Coverage of all I/O classes and related classes * In-depth coverage of Java's number formatting facilities and its support for international character sets

Rather than present you with another reference, Harnessing Hibernate lets you explore the system, from download and configuration through a series of projects that demonstrate how to accomplish a variety of practical goals. The new edition of this concise guide walks you through Hibernate's primary features, which include mapping from Java classes to database tables, and from Java data types to SQL data types. You will also learn about Hibernate's data query and retrieval facilities, and much more. By reading and following along with the examples, you can get your own Hibernate environment set up quickly and start using it for real-world tasks right away. Harnessing Hibernate teaches you how to: * Perform Object/Relational mapping * Work with persistent data from Java code * Work with groups and relationships between objects * Extend Hibernate's rich type support for your own needs * Simplify query creation using criteria and examples * Use the Hibernate Query Language (HQL) and understand how it differs from SQL * Use Hibernate in conjunction with Spring * Use Hibernate in conjunction with other packages, such as the Stripes web framework and the Eclipse IDE Once you're past the first few chapters, you can jump to topics that you find particularly interesting or relevant. All background material and explanations of how Hibernate works and why is in the service of a focused task. Source code can be downloaded from the book's website. If using SQL is an uncomfortable chore, Harnessing Hibernate offers you an effective and trouble-free method for working with the information you store in your applications.

In this compact book, Steven Feuerstein, widely recognized as one of the world's leading experts on the Oracle PL/SQL language, distills his many years of programming, teaching, and writing about PL/SQL into a set of best practices-recommendations for developing successful applications. Covering the latest Oracle release, Oracle Database 11gR2, Feuerstein has rewritten this new edition in the style of his bestselling Oracle PL/SQL Programming. The text is organized in a problem/solution format, and chronicles the programming exploits of developers at a mythical company called My Flimsy Excuse, Inc., as they write code, make mistakes, and learn from those mistakes-and each other. This book offers practical answers to some of the hardest questions faced by PL/SQL developers, including: * What is the best way to write the SQL logic in my application code? * How should I write my packages so they can be leveraged by my entire team of developers? * How can I make sure that all my team's programs handle and record errors consistently? Oracle PL/SQL Best Practices summarizes PL/SQL best practices in nine major categories: overall PL/SQL application development; programming standards; program testing, tracing, and debugging; variables and data structures; control logic; error handling; the use of SQL in PL/SQL; building procedures, functions, packages, and triggers; and overall program performance. This book is a concise and entertaining guide that PL/SQL developers will turn to again and again as they seek out ways to write higher quality code and more successful applications. "This book presents ideas that make the difference between a successful project and one that never gets off the ground. It goes beyond just listing a set of rules, and provides realistic scenarios that help the reader understand where the rules come from. This book should be required reading for any team of Oracle database professionals." --Dwayne King, President, KRIDAN Consulting

"We the Media, has become something of a bible for those who believe the online medium will change journalism for the better." - "Financial Times". Big Media has lost its monopoly on the news, thanks to the Internet. Now that it's possible to publish in real time to a worldwide audience, a new breed of grassroots journalists are taking the news into their own hands. Armed with laptops, cell phones, and digital cameras, these readers-turned-reporters are transforming the news from a lecture into a conversation. In "We the Media", nationally acclaimed newspaper columnist and blogger Dan Gillmor tells the story of this emerging phenomenon and sheds light on this deep shift in how we make - and consume - the news. Gillmor shows how anyone can produce the news, using personal blogs, Internet chat groups, email, and a host of other tools. He sends a wake-up call to newsmakers - politicians, business executives, celebrities - and the marketers and PR flacks who promote them. He explains how to successfully play by the rules of this new era and shift from "control" to "engagement." And, he makes a strong case to his fell journalists that, in the face of a plethora of Internet-fueled news vehicles, they must change or become irrelevant. Journalism in the 21st century will be fundamentally different from the Big Media oligarchy that prevails today. "We the Media" casts light on the future of journalism, and invites us all to be part of it. Dan Gillmor is founder of Grassroots Media Inc., a project aimed at enabling grassroots journalism and expanding its reach. The company's first launch is Bayosphere.com, a site "of, by, and for the San Francisco Bay Area." From 1994-2004, Gillmor was a columnist at the "San Jose Mercury News", Silicon Valley's daily newspaper, and wrote a weblog for SiliconValley.com. He joined the "Mercury News" after six years with the Detroit Free Press. Before that, he was with the "Kansas City Times" and several newspapers in Vermont. He has won or shared in several regional and national journalism awards. Before becoming a journalist, he played music professionally for seven years.

This practical guide shows you how to make your Java web applications more responsive and dynamic by incorporating new Ajaxian features, including suggestion lists, drag-and-drop, and more. Java developers can choose between many different ways of incorporating Ajax, from building JavaScript into your applications "by hand" to using the new Google Web Toolkit (GWT). "Ajax on Java" starts with an introduction to Ajax, showing you how to write some basic applications that use client-side JavaScript to request information from a Java servlet and display it without doing a full page reload. It also presents several strategies for communicating between the client and the server, including sending raw data, and using XML or JSON (JavaScript Object Notation) for sending more complex collections of data. The book then branches out into different approaches for incorporating Ajax, which include: the Prototype and script.aculo.us Javascript libraries, the Dojo and Rico libraries, and DWR; integrating Ajax into Java ServerPages (JSP) applications; using Ajax with Struts; integrating Ajax into Java ServerFaces (JSF) applications; and, using Google's GWT, which offers a pure Java approach to developing web applications: your client-side components are written in Java, and compiled into HTML and JavaScript. Ajax gives web developers the ability to build applications that are more interactive, more dynamic, more exciting and enjoyable for your users. If you're a Java developer and haven't tried Ajax, but would like to get started, this book is essential. Your users will be grateful.
