If you're up on the latest Java technologies, then you know that Enterprise JavaBeans (EJB) 3.0 is the hottest news in Java this year. In fact, EJB 3.0 is being hailed as the new standard of server-side business logic programming. And O'Reilly's award-winning book on EJB has been refreshed just in time to capitalize on the technology's latest rise in popularity.

This fifth edition, written by Bill Burke and Richard Monson-Haefel, has been updated to capture the very latest need-to-know Java technologies in the same award-winning fashion that drove the success of the previous four strong-selling editions. Bill Burke, Chief Architect at JBoss, Inc., represents the company on the EJB 3.0 and Java EE 5 specification committees. Richard Monson-Haefel is one of the world's leading experts on Enterprise Java.

Enterprise JavaBeans 3.0, 5th Edition is organized into two parts: the technical manuscript followed by the JBoss workbook. The technical manuscript explains what EJB is, how it works, and when to use it. The JBoss workbook provides step-by-step instructions for installing, configuring, and running the examples from the manuscript on the JBoss 4.0 Application Server.

Although EJB makes application development much simpler, it's still a complex and ambitious technology that requires a great deal of time to study and master. But now, thanks to Enterprise JavaBeans 3.0, 5th Edition, you can overcome the complexities of EJBs and learn from hundreds of practical examples that are largeenough to test key concepts but small enough to be taken apart and explained in the detail that you need. Now you can harness the complexity of EJB with just a single resource by your side.

SQL (Structured Query Language) is a standard programming language for generating, manipulating, and retrieving information from a relational database. If you're working with a relational database--whether you're writing applications, performing administrative tasks, or generating reports--you need to know how to interact with your data. Even if you are using a tool that generates SQL for you, such as a reporting tool, there may still be cases where you need to bypass the automatic generation feature and write your own SQL statements.

To help you attain this fundamental SQL knowledge, look to Learning SQL, an introductory guide to SQL, designed primarily for developers just cutting their teeth on the language.

Learning SQL moves you quickly through the basics and then on to some of the more commonly used advanced features. Among the topics discussed:
The history of the computerized databaseSQL Data Statements--those used to create, manipulate, and retrieve data stored in your database; example statements include select, update, insert, and deleteSQL Schema Statements--those used to create database objects, such as tables, indexes, and constraintsHow data sets can interact with queriesThe importance of subqueriesData conversion and manipulation via SQL's built-in functionsHow conditional logic can be used in Data StatementsBest of all, Learning SQL talks to you in a real-world manner, discussing various platform differences that you're likely to encounter and offering a series of chapter exercises that walk you through the learning process. Whenever possible, the book sticks to the features included in the ANSI SQL standards. This means you'll be able to apply what you learn to any of several different databases; the book covers MySQL, Microsoft SQL Server, and Oracle Database, but the features and syntax should apply just as well (perhaps with some tweaking) to IBM DB2, Sybase Adaptive Server, and PostgreSQL.
Put the power and flexibility of SQL to work. With Learning SQL you can master this important skill and know that the SQL statements you write are indeed correct.

When Microsoft releases Windows Vista, the new operating system will support applications that employ graphics now used by computer games--clear, stunning, and active. The cornerstone for building these new user interfaces is XAML ("Zammel"), the XML-based markup language that works with Windows Presentation Foundation (WPF), Vista's new graphics subsystem.

An acronym for Extensible Application Markup Language, XAML offers a wealth of new controls and elements with exciting capabilities, including animation and rendering of 3D graphics. Windows developers are already jazzed by the possibilities of using XAML for fixed and flow format documents like PDF and HTML, 2D and 3D vector-based graphics, form development, animation, audio and video, transparent layering, and a lot more. Many feel that XAML will eliminate the need for multiple file formats or plug-ins (read: Flash), while lowering development costs and reducing time to market.

The problem is, most developers don't know XAML. While it is fairly easy to understand, you still need a quick guide to bring you up to speed before Vista's release, and that's where this book's simple, no nonsense approach comes in.

XAML in a Nutshell covers everything necessary to design user interfaces and .NET applications that take advantage of WPF. Prerequisites such as Microsoft's new unified build system, MSBuild, and core XAML constructs and syntax--including shortcuts--are all presented with plenty of examples to get you started. The Core XAML Reference section lets you dig even deeper into syntax rules and attributes for all XAML elements with a series of quick-reference chapters. This section divides XAML elements into logical categories of elements, controls, shapes and geometry, layout, animations, and transformations for easy reference.

XAML in a Nutshell helps you learn, firsthand, how to use this XML-based markup language to implement the new generation of user interface graphics. As one reviewer noted, "Strong code examples and an efficient, conversational style take the tedium out of learning XAML and make the subject understandable--even interesting."

Have we entered the age of NoOps infrastructures? Hardly. Old-style system administrators may be disappearing in the face of automation and cloud computing, but operations have become more significant than ever. As this OReilly Radar Report explains, were moving into a more complex arrangement known as "DevOps."

Mike Loukides, OReillys VP of Content Strategy, provides an incisive look into this new world of operations, where IT specialists are becoming part of the development team. In an environment with thousands of servers, these specialists now write the code that maintains the infrastructure. Even applications that run in the cloud have to be resilient and fault tolerant, need to be monitored, and must adjust to huge swings in load. That was underscored by Amazons EBS outage last year.

From the discussions at OReillys Velocity Conference, its evident that many operations specialists are quickly adapting to the DevOps reality. But as a whole, the industry has just scratched the surface. This report tells you why.

Computer security is an ongoing process, a relentless contest between system administrators and intruders. A good administrator needs to stay one step ahead of any adversaries, which often involves a continuing process of education. If you're grounded in the basics of security, however, you won't necessarily want a complete treatise on the subject each time you pick up a book. Sometimes you want to get straight to the point. That's exactly what the new Linux Security Cookbook does. Rather than provide a total security solution for Linux computers, the authors present a series of easy-to-follow recipes--short, focused pieces of code that administrators can use to improve security and perform common tasks securely.The Linux Security Cookbook includes real solutions to a wide range of targeted problems, such as sending encrypted email within Emacs, restricting access to network services at particular times of day, firewalling a webserver, preventing IP spoofing, setting up key-based SSH authentication, and much more. With over 150 ready-to-use scripts and configuration files, this unique book helps administrators secure their systems without having to look up specific syntax. The book begins with recipes devised to establish a secure system, then moves on to secure day-to-day practices, and concludes with techniques to help your system stay secure.Some of the "recipes" you'll find in this book are:
Controlling access to your system from firewalls down to individual services, using iptables, ipchains, xinetd, inetd, and moreMonitoring your network with tcpdump, dsniff, netstat, and other toolsProtecting network connections with Secure Shell (SSH) and stunnelSafeguarding email sessions with Secure Sockets Layer (SSL)Encrypting files and email messages with GnuPGProbing your own security with password crackers, nmap, and handy scriptsThis cookbook's proven techniques are derived from hard-won experience. Whether you're responsible for security on a home Linux system or for a large corporation, or somewhere in between, you'll find valuable, to-the-point, practical recipes for dealing with everyday security issues. This book is a system saver.
