public abstract class Application

extends java.lang.Object

This abstract Application class a basic class for all EXT applications.

• providing the XML Namespaces naming services, like assigning a NS-qualified name an int code, used internally by SAXON NamePool.
• registering classes for dynamic instantiation of classes in derived applications (like in ServletApplication).
• logging
• setting the XML environment: DocumentBuilderFactory, default docBuilder, default encoding for transformation output, etc.
• providing the XML services: creating new DocumentBuilders, building a tree for actions attributes (HttpRequest, HttpSession, ServletConfig, ServletContext)
• setting the database environment: default SQL driver class
