JSP Implicit Objects
Actually Servlet don't have these implicit Objects After introducing of JSP it contains by default and with readymade Objects to use in our web applications.
These are available for programmer through Container. The implicit objects are parsed by the container and inserted into the generated servlet code. They are available only within the jspService method and not in any declaration. Implicit objects are used for different purposes. Our own methods (user defined methods) can't access them as they are local to the service method and are created at the conversion time of a jsp into a servlet.
These are 9 implicit Objects
