What is ExternalContext?
The ExternalContext class, a member of javax.faces.context package, is there so that JSF does not need to depend on any particular container. Thanks to this class, JSF can run in either a servlet or a portlet. In a servlet environment, you can get information contained in the ServletContext, ServletRequest, and ServletResponse objects through the instance of ExternalContext.
