XMLContentHandler provides a structured approach to building a data structure from XML content using SAX parser. Generally most of the data structures can be built in a top down approach where a parent gets created first and then children add themselves to the parent. This utility class facilitates building data structures in such a top down approach. ... more »

This article introduces a Java-XML binding technique based on VTD-XML and XPath. This approach doesn't mandate a schema, takes advantage of XML's inherent loose encoding, and avoids needless object creation, so it is much more efficient for lightweight data binding.... more »

Using Java API for XML Web Services (JAX-WS) technology to design and develop Web services yields many benefits, including simplifying the construction of Web services and Web service clients in Java, easing the development and deployment of Web services, and speeding up Web services development. This tutorial walks you through how to do all of this and more by developing a sample order-processing application that exposes its functionality as Web services. After going through this tutorial, you'll be able to apply these concepts and your newly acquired knowledge to develop Web services for your application using JAX-WS technology.... more »

You can do all sorts of interesting things with XML, but if you can't persist it to a file, it's all for naught. Brett McLaughlin discusses different tactics for XML persistence, and the pros and cons of each.... more »

Looking back over the last six years, it is hard to imagine networked computing without the Web. The reason why the Web succeeded where earlier hypertext schemes failed can be traced to a couple of basic factors: simplicity and ubiquity. From a service provider's (e.g. an e-shop) point of view, if they can set up a web site they can join the global community. From a client's point of view, if you can type, you can access services. From a service API point of view, the majority of the web's work is done by 3 methods (GET, POST, and PUT) and a simple markup language. The web services movement is about the fact that the advantages of the Web as a platform apply not only to information but to services.... more »
