Web services enable the new generation of Internet-based applications. These services support application-to-application Internet communication--that is, applications at different network locations can be integrated to function as if they were part of a single, large software system. Examples of applications made possible by Web services include automated business transactions and direct (nonbrowser) desktop and handheld device access to reservations, stock trading, and order-tracking systems. Several key standards have emerged that together form the foundation for Web services: XML (Extensible Markup Language), WSDL (Web Services Definition Language), SOAP (Simple Object Access Protocol), and UDDI (Universal Description, Discovery, and Integration). In addition, ebXML (Electronic Business XML) has been specified to facilitate automated business process integration among trading partners. This book introduces the main ideas and concepts behind core and extended Web services' technologies and provides developers with a primer for each of the major technologies that have emerged in this space. In addition, summarizes the major architectural approaches to Web services, examines the role of Web services within the .NET and J2EE communities, and provides information about major product offerings from BEA, Hewlett-Packard, IBM, IONA, Microsoft, Oracle, Sun Microsystems, and others. Understanding Web Services Key topics include: XML facilities for structuring and serializing data How WSDL maps services onto communication protocols and transports WSDL support for RPC-oriented and document-oriented interactions SOAP's required and optional elements Message processing and the role of intermediaries in SOAP UDDI data formats and APIs How ebXML offers an alternative to Web services that supports reliable messaging, security, and trading-partner negotiations With , you will be well informed and well positioned to participate in this vast, emerging marketplace.

Today MQSeries offers the programmer more choices than ever in which to write new MQSeries applications, from the most traditional Message Queue Interface API all the way through to the popular and highly portable JMS interface. Because of the many options available, it can sometimes be difficult for an application programmer new to MQSeries to easily understand the differences and benefits of each, or appreciate the implications of using one programming approach versus another. This redbook will help you install, tailor and configure specialist tools such as JMS admin, and will help you to design/create MQSeries applications. It gives a broad and general understanding of the currently available MQSeries APIs. We do this first by describing some of the more common examples and coding patterns, and then explaining each one in turn using the different APIs MQSeries supports to show the merits of each particular programming choice. This redbook positions the different MQSeries programming choices against each other in such a way as to help the application writer to make a clearer and more informed judgment as to which is the most suitable programming method for a particular situation.

As a developer new to Web Services, how do you make sense of thisemerging framework so you can start writing your own servicestoday? This concise book gives programmers both a concreteintroduction and a handy reference to XML web services, first byexplaining the foundations of this new breed of distributedservices, and then by demonstrating quick ways to create serviceswith open-source Java tools. Web Services make it possible fordiverse applications to discover each other and exchange dataseamlessly via the Internet. For instance, programs written in Javaand running on Solaris can find and call code written in C# thatrun on Windows XP, or programs written in Perl that run on Linux,without any concern about the details of how that service isimplemented. A common set of Web Services is at the core ofMicrosoft's new .NET strategy, Sun Microsystems's Sun One Platform,and the W3C's XML Protocol Activity Group. In this book, authorEthan Cerami explores four key emerging technologies: XML Remote Procedure Calls (XML-RPC) SOAP - The foundation for most commercial WebServices development Universal Discovery, Description and Integration(UDDI) Web Services Description Language (WSDL) For each of these topics, Web Services Essentials provides aquick overview, Java tutorials with sample code, samples of the XMLdocuments underlying the service, and explanations offreely-available Java APIs. Cerami also includes a guide to thecurrent state of Web Services, pointers to open-source tools and acomprehensive glossary of terms. If you want to break through theWeb Services hype and find useful information on these evolvingtechnologies, look no further than Web Services Essentials.

This concise book gives you the information you need to effectively use the Simple API for XML (SAX2), the dominant API for efficient XML processing with Java. With the SAX2 API, developers have access to the information in XML documents as they are read, without imposing major memory constraints or a large code footprint. SAX2 is often used by other APIs "under the covers", and provides a foundation for processing and creating both XML and non-XML information. While generally considered the most efficient approach to handling XML document parsing, SAX2 also carries a significant learning curve. In SAX2, author David Brownell explores the many details of managing XML parsers, filtering the information those parsers return, generating your own SAX2 events to convert non-XML information to an XML form, and developing strategies for using event-based parsing in a variety of application scenarios. Created in a public process by the XML-Dev mailing list, the SAX2 API is compact and highly functional. SAX2 uses callbacks to report the information in an XML document as the document is read, allowing you to create your own program structures around the content of documents. No intermediary model of an entire XML document is necessary, and the mapping from XML structures to Java structures and back is straightforward. Both developers learning about SAX2 for the first time and developers returning for reference and advanced material about SAX2 will find useful information in this book. Chapters provide detailed explanations and examples of many different aspects of SAX2 development, while appendices provide a reference to the API and an explanation of the relationships between the SAX2 API and the XML Information Set. While the core of the API is quite approachable, many of its more advanced features are both obscure and powerful. You can use SAX2 to filter, modify, and restructure information in layers of processing which make it easy to reuse generic tools. SAX2 also has some significant limitations that applications need to address in their own ways. This new book gives you the detail and examples required to use SAX2 to its full potential, taking advantage of its power while avoiding its limitations.

While the XML "buzz" still dominates talk among Internet developers, the critical need is for information that cuts through the hype and lets Java programmers put XML to work. Java & XML shows how to use the APIs, tools, and tricks of XML to build real-world applications, with the end result that both the data and the code are portable. This second edition of Java & XML adds chapters on Advanced SAX and Advanced DOM, new chapters on SOAP and data binding, and new examples throughout. A concise chapter on XML basics introduces concepts, and the rest of the book focuses on using XML from your Java applications. Java developers who need to work with XML, or think that they will in the future--as well as developers involved in the new peer-to-peer movement, messaging, or web services--will find the new Java & XML a constant companion. This book covers: The basics of XML, including DTDs, namespaces, XML Schema, XPath, and XSL The SAX API, including all handlers, the SAX 2 extensions, filters, and writers The DOM API, including DOM Level 2, Level 3, and the Traversal, Range, CSS, Events, and HTML modules. The JDOM API, including the core, a look at XPath support, and JDOM as a JSR Using web publishing frameworks like Apache Cocoon Developing applications with XML-RPC Using SOAP and UDDI for web services Data Binding, using both DTDs and XML Schema for constraints Building business-to-business applications with XML Building information channels with RSS and dynamic content with XSP Includes a quick reference on SAX 2.0, DOM Level 2, and JDOM.

Inside XSLT is designed to be a companion guide to Inside XML. This example oriented book covers XML to HTML, XML to Music, XML with Java, style sheet creation and usage, nodes and attributes, sorting data, creating Xpath expressions, using Xpath and XSLT functions, namespaces, names templates, name variables, designing style sheets and using XSLT processor API's, the 56 XSL formatting objects, the XSLT DTD, and much much more.

MySQL: Designing User Interfaces starts by introducing the functionality of GTK+ and how to migrate from Microsoft's Visual Basic. It then introduces MySQL as a simple, fast, reliable database for corporate applications. The book then flows into the how-to of combining GTK+ and MySQL through the coverage of the C API for MySQL because it is the "backend" to a GTK+ application. It then expands its coverage and teaches about heterogeneous network and deployment issues, as well as migration from existing systems to MySQL.

XML has been the biggest buzzword on the Internet community for the past year. But how do you cut through all the hype and actually put it to work? Java revolutionized the programming world by providing a platform-independent programming language. XML takes the revolution a step further with a platform-independent language for interchanging data. Java and XML share many features that are ideal for building web-based enterprise applications, such as platform-independence, extensibility, reusability, and global language (Unicode) support, and both are based on industry standards. Together Java and XML allow enterprises to simplify and lower costs of information sharing and data exchange. Java and XML shows how to put the two together, building real-world applications in which both the code and the data are truly portable. This book covers: The basics of XML Using standard Java APIs to parse XML Designing new document types using DTDs and Schemas Writing programs that generate XML data Transforming XML into different forms using XSL transformations (XSL/T) XML-RPC Using a web publishing framework like Apache-Cocoon This is the first book to cover the most recent versions of the DOM specification (DOM 2), the SAX API (SAX 2) and Sun's Java API for XML.

XML by Example teaches Web developers to make the most of XML with short, self-contained examples every step of the way. The book presumes knowledge of HTML, the Web, Web scripting, and covers such topics as: Document Type Definitions, Namespaces, Parser Debugging, XSL (Extensible Stylesheet Language), and DOM and SAX APIs. At the end, developers will review the concepts taught in the book by building a full, real-world e-commerce application.

MySQL and mSQL are popular and robust database products that support key subsets of SQL on both Linux and Unix systems. Both products are free for nonprofit use and cost a small amount for commercial use. Even a small organization or web site has uses for a database. Perhaps you keep track of all your customers and find that your information is outgrowing the crude, flat-file format you started with. Or you want to ask your web site's visitors for their interests and preferences and put up a fresh web page that tallies the results. Unlike commercial databases, MySQL and mSQL are affordable and easy to use. If you know basic C, Java, Perl, or Python, you can quickly write a program to interact with your database. In addition, you can embed queries and updates right in an HTML file so that a web page becomes its own interface to the database. This book is all you need to make use of MySQL or mSQL. It takes you through the whole process from installation and configuration to programming interfaces and basic administration. Includes reference chapters and ample tutorial material. Topics include: Introductions to simple database design and SQL Building, installation, and configuration Basic programming APIs for C, C++, Java (JDBC), Perl, and Python CGI programming with databases in C and Perl Web interfaces: PHP, W3-mSQL, Lite, and mSQLPerl

Oracle is the most popular database management system in use today, and PL/SQL plays a pivotal role in current and projected Oracle products and applications. PL/SQL is a programming language providing procedural extensions to the SQL relational database language and to an ever-growing number of oracle development tools. originally a rather limited tool, PL/SQL became with Oracle7 a mature and effective language for developers. now, with the introduction of Oracle8, PL/SQL has taken the next step towards becoming a fully realized programming language providing sophisticated object-oriented capabilities. Steven Feuerstein's Oracle PL/SQL Programming is a comprehensive guide to building applications with PL/SQL. That book has become the bible for PL/SQL developers who have raved about its completeness, readability, and practicality. Built-in packages are collections of PL/SQL objects built by Oracle Corporation and stored directly in the Oracle database. The functionality of these packages is available from any programming environment that can call PL/SQL stored procedures, including Visual Basic, Oracle Developer/2000, Oracle Application Server (for web-based development), and, of course, the Oracle database itself. Built-in packages extend the capabilities and power of PL/SQL in many significant ways. for example: DBMS_SQL executes dynamically constructed SQL statements and PL/SQL blocks of code. DBMS_PIPE communicates between different Oracle sessions through a pipe in the RDBMS shared memory. DBMS_JOB submits and manages regularly scheduled jobs for execution inside the database. DBMS_LOB accesses and manipulates Oracle8's large objects (LOBs) from within PL/SQL programs. 1. Introduction Executing Dynamic SQL and PL/SQL Intersession Communication User Lock and Transaction Management Oracle Advanced Queuing Generating Output from PL/SQL Programs Defining an Application Profile Managing Large Objects Datatype Packages Miscellaneous Packages Managing Session Information Managing Server Resources Job Scheduling in the Database Snapshots Advanced Replication Conflict Resolution Deferred Transactions and Remote Procedure Calls The first edition of Oracle PL/SQL Programming contained a chapter on Oracle's built-in packages. but there is much more to say about the basic PL/SQL packages than Feuerstein could fit in his first book. In addition, now that Oracle8 has been released, there are many new Oracle8 built-in packages not described in the PL/SQL book. There are also packages extensions for specific oracle environments such as distributed database. hence this book. Oracle Built-in Packages pulls together information about how to use the calling interface (API) to Oracle's Built-in Packages, and provides extensive examples on using the built-in packages effectively. The windows diskette included with the book contains the companion guide, an online tool developed by RevealNet, Inc., that provides point-and-click access to the many files of source code and online documentation developed by the authors. The table of contents follows: Preface Part I: Overview Part II: Application Development Packages Part III: Server Management Packages Part IV: Distributed Database Packages Appendix.
