Sportwire is an archiving and presentation system for XML documents distributed by sports newswire services. Sportwire is specifically designed for the Sportsticker, SportsNetwork and AFP XML feeds, but should be adaptable to any XML-based news feed which provides an event-centric description of sports news. This document describes the software components of the Sportwire system.

Servlet/JSP Terminology

Bean Scope

JavaBeans are Java classes available from within Java Server Pages. The scope of a bean can be set to persist over the entire server, the current application, the current page, or the current session; Sportwire uses singleton bean classes with page scope so every reference from a given JSP page accesses the same report cache object.


Java packages for transferring data between XML documents and relational databases. XMLDBMS supports schemas written in Data Definition Markup Language (DDML). For more information, visit the XMLDBMS Website.


An alternative XML Document model providing more Java-friendly access container methods. JDOM also provides methods to interoperate with W3C Document software.
