Two hot topics come together in this developer's guide from Brett McLaughlin, Java and XML. Both Java and XML are cross-platform technologies; by using Java for code and XML for transporting data, you can build truly portable applications. This title is aimed at intermediate to advanced programmers; while XML topics are explained more or less from scratch, readers will need prior knowledge of Java.
The book begins with an overview of XML and its uses, and goes on to explain how to parse XML by using the Simple API for XML (SAX 2). Next, there is coverage of how XML is validated by using Document Type Definitions (DTDs) and XML Schema, and transformed by using eXtensible Stylesheet Language (XSL). Brief coverage of Sun's Java API for XML is followed by a detailed look at the Java Document Object Model (JDOM), a new API devised by the author in association with O'Reilly, the publisher.
The last part of the book is more advanced, and covers applications of XML and Java. There are chapters on Web-publishing frameworks, XML Remote Procedure Calls (RPCs), using XML to read and write configuration data, and generating XML with Java. There is also a short business-to-business example. Appendices provide an API reference to the various specifications discussed in the book.
The strengths of Java and XML include the author's deep knowledge of his subject, and a writing style that is both clear and enthusiastic. If you happen to know a lot about Java and not much about XML, this is the ideal title. Readers who already have a good grasp of XML basics might be frustrated by the amount of introductory material. --Tim Anderson
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)
- 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.
