There are certain implicit variables available to a JSP:

• request – reference to the HttpServletRequest
• response – reference to the HttpServletResponse
• pageContext – provides access to the namespaces within the JSP
• session – reference to the HttpSession
• application – reference to the ServletContext
• config – reference to the ServletConfig
• page – reference to the current instance of the JSP being accessed; analogous to using this in the generated Servlet for this JSP
• exception – reference to the uncaught exception thrown by a JSP; only available on JSPs with the isErrorPage set to true
