All Implemented Interfaces:

java.lang.Cloneable, java.util.Map, java.io.Serializable

public class StrutsCXPropertiesReader

extends com.oreilly.javaxml2.XMLProperties

A helper class which reads in the properties.xml and writes a XMLProperties object into the ServletContext. Make sure the /WEB-INF/properties.xml is present!

Caching & Performance Tuning:
The properties are read once at first call to the StrutsCXBaseAction and saved there as a field parameter available to all Action classes.

NOTE: Changes to the properties.xml afford to reload the application!

Future Improvements: A future release should and will replace this mechanism with the new JDK 1.4 Preferences!
