All Implemented Interfaces:

JAXXContext

public class DefaultApplicationContext
extends DefaultJAXXContext

The default context to be used for an application. This extends the DefaultJAXXContext and add a possibility to auto-instanciate some classes asked via DefaultJAXXContext.getContextValue(Class) and getContextValue(Class, String) methods. To registred a such class, just annotate your class with DefaultApplicationContext.AutoLoad.
