All Implemented Interfaces:: java.io.Serializable, java.lang.Cloneable, java.util.Map, Context

public class ServletWebContext
extends WebContext
extends WebContext

Concrete implementation of WebContext suitable for use in Servlets and JSP pages. The abstract methods are mapped to the appropriate collections of the underlying servlet context, request, and response instances that are passed to the constructor (or the initialize method).
