eXist-db is an open source database management system built using XML technology. It stores XML data according to the XML data model and features efficient, index-based XQuery processing.
XPath is used to navigate through elements and attributes in an XML document. XPath is a major element in W3C's XSLT standard - and XQuery and XPointer are both built on XPath expressions.
Jersey 1.0 is an open-source, production-ready reference implementation of JAX-RS, the Java API for RESTful Web Services (JSR-311). Jersey makes it easy to create RESTful web services in Java.
In an earlier Tech Tip, Implementing RESTful Web Services in Java, Paul Sandoz and I introduced RESTful Web Services, JAX-RS, and Jersey, and showed how to write RESTful web services in Java that conform to the JAX-RS specification. In this tip you will learn how to configure data in JSON (JavaScript Object Notation) using Jersey 1.0. JSON is a lightweight data-interchange format that is based on the object notation of the JavaScript language. Because of it's simple text format, JSON provides a good alternative to other data interchange formats such as XML and is particularly attractive as a data interchange format for RESTful web services.
In this tip you will build a Jersey-based web application that provides information about printer status. The application returns the information in JSON format. To build the application, you will use the Maven 2 software project management tool. For more information about Maven, see Welcome to Maven and Building Web Applications with Maven 2.
This project started from my frustration that I could not find any simple, portable XML Parser to use inside my tools (see CONDOR for example). Let's look at the well-known Xerces C++ library: the complete Xerces project is 53 MB! (11 MB compressed in a zipfile). I am currently developping many small tools. I am using XML as standard for all my input /ouput configuration and data files. The source code of my small tools is usually around 600KB.
APML allows users to share their own personal Attention Profile in much the same way that OPML allows the exchange of reading lists between News Readers.
