JSP implicit objects

Every JSP file has 9 implicit object which you can use directly without being declared.
Implicit objects are the objects that are available for the use in JSP documents without being declared first. These objects are parsed by the JSP engine and inserted into the generated Servlet.
JSP implicit objects are as below:

Implicit object	Scope	comment
request	Request	request
response	Page	response
pageContext	Page	page environment
session	Session	session
application	Application	same as ServeletContext
out	Page	Writing to the outputstream
config	Page	same as ServeletConfig
page	Page	this pasge's Servlet
exception	Page	exception created on this page

Note: If you have your own object defined with same name as the implicit Object, then Implicit objects take precedence over your object. So, avoid to use implicit object name as your own object.
