The implicit JSP object pageContext is an instance of the implementation of the abstract javax.servlet.jsp.PageContext class . We can use the pageContext object to get and set attributes with different scopes and to forward requests to another resource. This object also has a link to another implicit object. This is the only object that is represented in JSP implicit objects and JSP EL implicit objects.
