Threads are essential to Java programming, but learning to use them effectively is a nontrivial task. This new edition of the classic Java Threads shows you how to take full advantage of Java's threading facilities and brings you up-to-date with the watershed changes in Java 2 Standard Edition version 5.0 (J2SE 5.0). It provides a thorough, step-by-step approach to threads programming. Java's threading system is simple relative to other threading systems. In earlier versions of Java, this simplicity came with tradeoffs: some of the advanced features in other threading systems were not available in Java. J2SE 5.0 changes all that: it provides a large number of new thread-related classes that make the task of writing multithreaded programs that much easier. You'll learn where to use threads to increase efficiency, how to use them effectively, and how to avoid common mistakes. This book discusses problems like deadlock, race conditions, and starvation in detail, helping you to write code without hidden bugs. Java Threads, Third Edition, has been thoroughly expanded and revised. It incorporates the concurrency utilities from java.util.concurrent throughout. New chapters cover thread performance, using threads with Swing, threads and Collection classes, thread pools, and threads and I/O (traditional, new, and interrupted). Developers who cannot yet deploy J2SE 5.0 can use thread utilities provided in the Appendix to achieve similar functionality with earlier versions of Java. Topics include: Lock starvation and deadlock detection; Atomic classes and minimal synchronization (J2SE 5.0); Interaction of Java threads with Swing, I/O, and Collection classes; Programmatically controlled locks and condition variables (J2SE 5.0); Thread performance and security; Thread pools (J2SE 5.0); Thread groups; Platform-specific thread scheduling; Task schedulers (J2SE 5.0); Parallelizing loops for multiprocessor machines In short, this new edition of Java Threads covers everything you need to know about threads, from the simplest animation program to the most complex applications. If you plan to do any serious work in Java, you will find this book invaluable.

You've probably heard the buzz about Eclipse, the powerful open source platform that gives Java developers a new way to approach development projects. It's like a shiny new car--no longer content to just admire Eclipse, you're now itching to get in and drive. Eclipse is to Java developers what Visual Studio is to .NET developers--it's an integrated development environment (IDE) that combines a code editor, compiler, debugger, text editor, graphical user interface (GUI) builder, and other components into a single, user-friendly application. It provides a solid foundation that enables Java developers to construct and run integrated software-development tools for web development, application design, modeling, performance, testing, and much more. As with any extensive programming tool, however, there's a lot to learn. And there s no better guy than well-known Java expert Steve Holzner to teach you. An award-winning and best-selling author who has been writing about Java topics since the language first appeared, Holzner delivers just the kind of targeted, practical, everyday knowledge you need to hone your mastery of Eclipse. Perfect as a companion to an Eclipse programming tutorial (such as Holzner's own Eclipse, O'Reilly, April 2004) or an ideal stand-alone for all those developers who either don't want or don't need the tutorial approach, the Eclipse Cookbook contains task-oriented recipes for more than 800 situations you may encounter while using this new Java platform--from deploying a web application automatically to reverse engineering compiled code, from re-naming all references to a class across multiple packages to initializing the SWT JNI libraries. Each recipe in the ever-popular and utterly practical problem-solution-discussion format for O'Reilly cookbooks contains a clear and thorough description of the problem, a brief but complete discussion of a solution, and in-action examples illustrating that solution. The Eclipse Cookbook will satiate Java programmers at all levels who are ready to go beyond tutorials--far beyond writing plug-ins and extensions--and actually use the powerful and convenient Eclipse day to day.

The annoyance factor for individual users whose email is crammed with pitches for pornography, absurd moneymaking schemes, and dubious health products is fierce. But for organizations, the cost of spam in lost productivity and burned bandwidth is astronomical. While society is grappling with a solution to the burgeoning crisis of spam proliferation, the pressure is on system administrators to find a solution to this massive problem in-house. And fast. Sys admins can field scores of complaints and spend months testing software suites that turn out to be too aggressive, too passive, or too complicated to setup only to discover that SpamAssassin (SA), the leading open source spam-fighting tool, is free, flexible, powerful, highly-regarded, and remarkably effective. The drawback? SpamAssassin's lack of published documentation. SpamAssassin by Alan Schwartz, is the only published resource devoted to SpamAssassin and how to integrate it effectively into your networks. This clear, concise guide clarifies the installation, configuration, and use of the SpamAssassin spam-checking system (versions 2.63 and 3.0 ) for Unix system administrators using the Postfix, Sendmail, Exim, or qmail mail servers, helping administrators make the right integration decision for their particular environments. It covers concrete advice on how to: * Customize SpamAssassin's rules, and even create new ones Train SpamAssassin's Bayesian classifier, a statistical engine for detecting spam, to optimize it for the sort of email that you typically receive * Block specific addresses, hosts, and domains using third-party blacklists like the one maintained by Spamcop.net. * Whitelist known good sources of email, so that messages from clients, coworkers, and friends aren't inadvertently lost. * Configure SpamAssassin to work with newer spam-filtering methods such as Hashcash (www.hashcash.org) and Sender Policy Framework (SPF). Sys admins, network administrators, and ISPs pay for spam with hours of experimentation and tedious junk email management, frayed user tempers, and their sanity. SpamAssassin, together with this essential book, give you the tools you need to take back your organization's inboxes. "Detailed, accurate and informative--recommended for spam-filtering beginners and experts alike." --Justin Mason, SpamAssassin development team

Sometimes the simplest answer is the best. Many Enterprise Java developers, accustomed to dealing with Java's spiraling complexity, have fallen into the habit of choosing overly complicated solutions to problems when simpler options are available. Building server applications with "heavyweight" Java-based architectures, such as WebLogic, JBoss, and WebSphere, can be costly and cumbersome. When you've reached the point where you spend more time writing code to support your chosen framework than to solve your actual problems, it's time to think in terms of simplicity. In Better, Faster, Lighter Java authors Bruce Tate and Justin Gehtland argue that the old heavyweight architectures are unwieldy, complicated, and contribute to slow and buggy application code. As an alternative means for building better applications, the authors present two "lightweight" open source architectures: Hibernate--a persistence framework that does its job with a minimal API and gets out of the way, and Spring--a container that's not invasive, heavy or complicated. Hibernate and Spring are designed to be fairly simple to learn and use, and place reasonable demands on system resources. Better, Faster, Lighter

More often than not, the words "sendmail configuration" strike dread in the hearts of sendmail and system administrators--and not without reason. sendmail configuration languages are as complex as any other programming languages, but used much more infrequently--only when sendmail is installed or configured. The average system administrator doesn't get enough practice to truly master this inscrutable technology. Fortunately, there's help. The sendmail Cookbook provides step-by-step solutions for the administrator who needs to solve configuration problems fast. Say you need to configure sendmail to relay mail for your clients without creating an open relay that will be abused by spammers. A recipe in the Cookbook shows you how to do just that. No more wading through pages of dense documentation and tutorials and creating your own custom solution--just go directly to the recipe that addresses your specific problem. Each recipe in the sendmail Cookbook outlines a configuration problem, presents the configuration code that solves that problem, and then explains the code in detail. The discussion of the code is critical because it provides the insight you need to tweak the code for your own circumstances. The sendmail Cookbook begins with an overview of the configuration languages, offering a quick how-to for downloading and compiling the sendmail distribution. Next, you'll find a baseline configuration recipe upon which many of the subsequent configurations, or recipes, in the book are based. Recipes in the following chapters stand on their own and offer solutions for properly configuring important sendmail functions such as: Delivering and forwarding mail Relaying Masquerading Routing mail Controlling spam Strong authentication Securing the mail transport Managing the queue Securing sendmail sendmail Cookbook is more than just a new approach to discussing sendmail configuration. The book also provides lots of new material that doesn't get much coverage elsewhere--STARTTLS and AUTH are given entire chapters, and LDAP is covered in recipes throughout the book. But most of all, this book is about saving time--something that most system administrators have in short supply. Pick up the sendmail Cookbook and say good-bye to sendmail dread.

With the spread of Web-enabled desktop clients and web-server based applications, developers can no longer afford to treat security as an afterthought. It's one topic, in fact, that .NET forces you to address, since Microsoft has placed security-related features at the core of the .NET Framework. Yet, because a developer's carelessness or lack ofexperience can still allow a program to be used in an unintended way, Programming .NET Security shows you how the various tools will help you write secure applications. The book works as both a comprehensive tutorial and reference to security issues for .NET application development, and contains numerous practical examples in both the C# and VB.NET languages. With Programming .NET Security, you will learn to apply sound security principles to your application designs, and to understand the concepts of identity, authentication and authorization and how they apply to .NET security. This guide also teaches you to: use the .NET run-time security features and .N ET security namespaces and types to implement best-practices in your applications, including evidence, permissions, code identity and security policy, and role based and Code Access Security (CAS); use the .NET cryptographic APIs , from hashing and common encryption algorithms to digital signatures and cryptographic keys, to protect your data; and use COM+ component services in a secure manner. If you program with ASP.NET will also learn how to apply security to your applications. And the book also shows you how to use the Windows Event Log Service to audit Windows security violations that may be a threat to your solution.

Architects of buildings and architects of software have more in common than most people think. Both professions require attention to detail, and both practitioners will see their work collapse around them if they make too many mistakes. It's impossible to imagine a world in which buildings get built without blueprints, but it's still common for software applications to be designed and built without blueprints, or in this case, design patterns. A software design pattern can be identified as "a recurring solution to a recurring problem." Using design patterns for software development makes sense in the same way that architectural design patterns make sense--if it works well in one place, why not use it in another? But developers have had enough of books that simply catalog design patterns without extending into new areas, and books that are so theoretical that you can't actually do anything better after reading them than you could before you started. Crawford and Kaplan's J2EE Design Patterns approaches the subject in a unique, highly practical and pragmatic way. Rather than simply present another catalog of design patterns, the authors broaden the scope by discussing ways to choose design patterns when building an enterprise application from scratch, looking closely at the real world tradeoffs that Java developers must weigh when architecting their applications. Then they go on to show how to apply the patterns when writing realworld software. They also extend design patterns into areas not covered in other books, presenting original patterns for data modeling, transaction / process modeling, and interoperability. J2EE Design Patterns offers extensive coverage of the five problem areas enterprise developers face: * Maintenance (Extensibility) * Performance (System Scalability) * Data Modeling (Business Object Modeling) * Transactions (process Modeling) * Messaging (Interoperability) And with its careful balance between theory and practice, J2EE Design Patterns will give developers new to the Java enterprise development arena a solid understanding of how to approach a wide variety of architectural and procedural problems, and will give experienced J2EE pros an opportunity to extend and improve on their existing experience.

Many serious Java programmers, especially enterprise Java programmers, consider the new I/O API--called NIO for New Input/Output--the most important feature in the 1.4 version of the Java 2 Standard Edition. The NIO package includes many things that have been missing from previous editions of Java that are critical to writing high-performance, large-scale applications: improvements in the areas of buffer management, scalable network and file I/O, character-set support, and regular expression matching. Most of all, it boosts performance and speed dramatically. Java NIO explores the new I/O capabilities of version 1.4 in detail and shows you how to put these features to work to greatly improve the efficiency of the Java code you write. This compact volume examines the typical challenges that Java programmers face with I/O and shows you how to take advantage of the capabilities of the new I/O features. You?ll learn how to put these tools to work using examples of common, real-world I/O problems and see how the new features have a direct impact on responsiveness, scalability, and reliability. The book includes: * A rundown of the new features in NIO * Basic and advanced I/O Concepts * Binary I/O and the new buffer classes * Memory mapped files and file locking * Character I/O: encoding, decoding and transforming character data * Regular Expressions and the new java.util.regex package * Muliplexing with java.nio Because the NIO APIs supplement the I/O features of version 1.3, rather than replace them, you'll also learn when to use new APIs and when the older 1.3 I/O APIs are better suited to your particular application. Java NIO is for any Java programmer who is interested in learning how to boost I/O performance, but if you're developing applications where performance is critical, such as game computing or large-scale enterprise applications, you'll want to give this book a permanent spot on your bookshelf. With the NIO APIs, Java no longer takes a backseat to any language when it comes to performance. Java NIO will help you realize the benefits of these exciting new features.

Mark provides insights into the workings of the rule-based optimizer that go well beyond what the rules tell you. He also provides solutions to many common problems that occur with both the rule-based and cost-based optimizers. In addition to the specific problem/solution scenarios for the optimizers, the book provides a number of SQL tuning tips. It discusses the various optimizer hints, telling you when they can be used to good effect. Finally, it discusses the use of the DBMS_STATS package to manage database statistics, and the use of outlines to specify execution plans for SQL statements in third-party applications that you can't otherwise modify..

Given Perl's natural fit for web applications development, it's no surprise that Perl is also a natural choice for web services development. It's the most popular web programming language, with strong implementations of both SOAP and XML-RPC, the leading ways to distribute applications using web services. But books on web services focus on writing these applications in Java or Visual Basic, leaving Perl programmers with few resources to get them started. Programming Web Services with Perl changes that, bringing Perl users all the information they need to create web services using their favorite language. Programming Web Services with Perl steers clear of the hype surrounding web services and concentrates on what is useful and practical. The book introduces the major web services standards, such as XML-RPC, SOAP, WSDL, and UDDI, and shows how to implement Perl servers and clients using these standards. You'll find detailed references on both the XML and SOAP toolkits, and learn when to use one technology in favor of the other. The book is rich with programming examples that you'll find useful well past the learning stage. And, moving beyond the basics, the book offers solutions to problems of security, authentication, and scalability. Some of the topics covered in the book are: * HTTP and XML basics * XML-RPC and the toolkits * SOAP and toolkits * SOAP::Lite * Using SOAP with SMTP and other protocols * Advertising and discovering with UDDI and WSDL * The REST methodology * The future of web services Programming Web Services with Perl was written for Perl programmers who have no prior knowledge of web services. You can pick up this book without any understanding of XML-RPC or SOAP and be able to apply these technologies easily, through the use of publicly available Perl modules detailed in the book. If you're interested in applying XML-RPC and SOAP technologies to distributed programming applications, then Programming Web Services with Perl is a book you'll want to have.

Java and SOAP provides Java developers with an in-depth look at SOAP (the Simple Object Access Protocol). Of course, it covers the basics: what SOAP is, why it's soared to a spot on the Buzzwords' Top Ten list, and what its features and capabilities are. And it shows you how to work with some of the more common Java APIs in the SOAP world: Apache SOAP and GLUE. In addition to covering the basics such as the structure of a SOAP message, SOAP encoding, and building simple services using RPC and messaging, Java and SOAP covers many topics that are essential to real-world development. Although SOAP has native support for an impressive number of object types, the nature of modern programming means that whatever SOAP gives you is not enough. When do you need to add support for your own object types, and how do you do it? How do you handle errors, and how do you add your own information to Fault messages? How do you handle attachments? In an ideal world, you could live entirely within Java, and ignore the SOAP messages being send back and forth: you'd be able to write Java code and let the SOAP APIs work behind the scenes. However, we're not yet in that ideal world, and won't be for some time. Therefore, Java and SOAP pays particular attention to how SOAP messages are encoded. It doesn't just explain the document types, but shows how the documents are used in practice as they are generated by the different APIs. If you ever have to debug interoperability problems, you'll find that this information is indispensable. We've always found that the best software is written by people who understand what's happening under the hood. SOAP is no different. Let's say you need to write a custom serializer to create a SOAP representation of a structure. How do you know that your encoding is efficient? There's one definitive answer: look at the SOAP documents it produces! Java and SOAP also discusses interoperability between the major SOAP platforms, including Microsoft's .NET, SOAP messaging, SOAP attachments, message routing, and a preview of the forthcoming AXIS APIs and server. If you're a Java developer who would like to start working with SOAP, this is the book you need to get going.

This text offers a vendor-neutral approach for designing large local area networks according to business or organizational needs, rather than from a product perspective. Kevin Dooley outlines "top-down network design" for building a technological infrastructure to fit your organization's requirements. Dooley argues that the design of a network is largely independent of the products used. Whether you use a Cisco or Juniper router, the same security issues and protocols apply. The questions he addresses in this book are need-specif ic: Do I use a router or a switch? Should I route between switched areas or switch between routed areas? The book covers topics from from security, bandwidth and scalability to network reliability, which includes backup, redundancy, and points of failure. Specific technologies are analyzed in detail: network topologies, routing and switching strategies, wireless, virtual LANs, firewalls and gateways, security, Internet protocols, bandwidth, and multicast services. The book also discusses proprietary technologies that are ubiquitous, such as Cisco's IOS and Novell's IPX.

Oracle database administration is a complex and stressful job. In a series of easy-to-use checklists, this concise pocket reference summarizes the enormous number of tasks you must perform as an Oracle DBA. Each section takes a step-by-step "cookbook" approach to presenting DBA quick-reference material. This reference guide is divided into three major sections covering the main areas of an Oracle DBA's responsibilities. The first, on database management, describes how to maintain existing databases (with a checklist of daily, weekly, and monthly activities), prepare new databases for production, and back up and recover databases (with checklists for how to recover tables, data files, index files, control files, rollback segments, and active and inactive redo logs). The section on installation and configuration contains a summary of key procedures for installation on Unix, Windows NT, and VMS platforms. It also includes special steps for configuring a parallel database. Finally, the section on network management helps with installing, configuring, and testing Net8 software on server and client machines. Tasks include confirming network availability and Net8 connectivity, verifying Net8 name resolution, configuring Net8 clients (with LDAP or Oracle Names), configuring Net8 on the server, configuring the Multi-Threaded Server (MTS), tracing client connections, and tracing the Net8 listener. This book's quick-reference, step-by-step approach aims to take the stress out of DBA problem solving.

The term "peer-to-peer" has come to be applied to networks that expect end users to contribute their own files, computing time, or other resources to some shared project. Even more interesting than the systems' technical underpinnings are their socially disruptive potential: in various ways they return content, choice, and control to ordinary users. While this book is mostly about the technical promise of peer-to-peer, it also talks about its exciting social promise. Communities have been forming on the Internet for a long time, but they have been limited by the flat interactive qualities of email and Network newsgroups. People can exchange recommendations and ideas over these media, but have great difficulty commenting on each other's postings, structuring information, performing searches, or creating summaries. If tools provided ways to organize information intelligently, and if each person could serve up his or her own data and retrieve others' data, the possibilities for collaboration would take off. Peer-to-peer technologies along with metadata could enhance almost any group of people who share an interest - technical, cultural, political, medical, you name it. This book presents the goals that drive the developers of the best-known peer-to-peer systems, the problems they've faced, and the technical solutions they've found.

With COM and .NET Component Services, skilled COM developers can leverage their knowledge for the next generation of components to be built for Microsoft's new .NET framework. A primary goal of Microsoft's COM+ is to provide proven design solutions for scalable systems. Assuming experience with classic COM, COM and .NET Component Services focuses on the added services of COM+, including support for transactions, queued components, events, concurrency management, and security. Along the way, it ably demonstrates that COM+ is a masterpiece of design and usability from the ground up--truly a mature set of component services oriented for the middle tier. COM+ provides a foundation for robust, enterprise-wide, mission-critical distributed applications. And it's not limited to Internet applications. You can use COM+ services in the same places as classic COM components: in-house two-tier information systems, client-tier controls, desktop applications, machine control components, and every other conceivable application of COM. COM and .NET Component Services is the first book to stress the importance of learning to use COM+ services for both .NET and COM component-based applications. Since most companies have considerable investment in existing code base and development skills, COM+ can serve as a migration path for companies and developers. Companies can start (or continue) their projects in COM, using COM+ as a supporting platform for component services, and then when the time comes to move to .NET, they can start plugging .NET components seamlessly into the same architecture, reusing and interacting with their existing COM components.

This reference describes the functions, classes, and templates in that part of the C++ standard library of ten referred to as the Standard Template Library (STL). The STL encompasses containers, iterators, algorithms, and function objects, which collectively represent one of the most important and widely used subsets of standard library functionality. The C++ standard library, even the subset known as the STL, is vast. It's next to impossible to work with the STL without some sort of reference at your side to remind you of template parameters, function invocations, return types - indeed, the entire myriad of details you need to know in order to use the STL effectively and get work done. You need a memory-aid. Programmers familiar with the STL need a small, lightweight memory-aid. That's what the STL Pocket Reference is. It's small, lightweight, and chock-full of information that you can take in at a glance, so you can get on with your work.

Linux is a powerful open-source operating system that has been around for many years and is widely used for running servers and websites. But most students and Makers encounter it for the first time when they are working on projects with their Raspberry Pi or similar single-board computers (SBCs) such as BeagleBone Black or Intel Galileo. Linux for Makers is the first book that explains the Linux operating system specifically for Makers, as opposed to programmers and administrators. By gaining a deeper understanding of Linux, Makers can add another useful tool to their kit that will help them build their projects more easily. Written with the Maker in mind, this book will focus mostly on Rasbian running on the Raspberry Pi as it is the most prolific in the ecosystem today. However most of the topics covered will apply broadly to other Linux distributions and will be called out when they may differ. Many times users cut and paste from a website tutorial into the Linux command line without understanding what they are actually doing only to be frustrated when they want to modify or tweak something to suit their needs. Also, many Makers shy away from using the Raspberry Pi or similar board because they feel Linux is too foreign and they think using a command line will be more difficult than using a GUI. This book aims to overcome those fears and provide a foundation for further learning and exploration. To that end, this book will focus on the basic principles that a Maker would need to know as opposed to other resources that go into detail that is not particularly relevant to building projects.
