The implicit page variable is simply a "this" reference to the JSP instance that is being invoked by the servlet container. This is an object provided by the container that fulfils the JspPage interface, and normally the HttpJspPage interface too. These interfaces are similar to the Servlet and HttpServlet interfaces and implement JSP lifecycle methods jspInit, jspDestroy and _jspService(HttpServletRequest, HttpServletResponse).

The JSP pageContext variable refers to an object that implements the PageContext interface. The page context has convenience methods to access common Web application variables, including the servlet configuration and context objects, request and response objects, request attributes, and session object.
