EL Implicit Object pageContext

 pageContext   

     

Introduction:

1.  This is the only one EL implicit object which matches with Jsp implicit objects.

2.  By using this implicit object we can bring all other implicit objects into EL and accessing servlet and JSP properties, such as a request's protocol or server port, or the major and minor versions of the servlet API your container supports.

3.  You can find out that information and much more with the pageContext implicit object, which gives you access to the request, response, session, and application (also known as the servlet context).

4.  Useful properties for the pageContext implicit object are listed in Table 2.6.

Property	Type	Description
request	ServletRequest	The current request
response	ServletResponse	The current response
servletConfig	ServletConfig	The servlet configuration
servletContext	ServletContext	The servlet context
session	HttpSession	The current session

Ex: 1.${pageContext.request.method}

       2.${pageContext.session.id}
