What are the difference between ServletContext and PageContext?
In JSP, the ServletContext shares information about the container in which the servlet is running in. This can be set up in the web application descriptor. There can be only one v ServletContext per web application. Compared to this, the PageContext gives the servlet information about the request that it is currently managing and contains information about the request, the response object, the session, and also a reference to the ServletContext of the web application.
