What are the life-cycle methods of JSP ?

jspInit()

The container calls the jspInit() to initialize the servlet instance.

It is called before any other method, and is called only once for a servlet instance.

_jspService()

The container calls the _jspservice() for each request and it passes the request and the response objects.

_jspService() method cann't be overridden.

jspDestroy()

The container calls this when its instance is about to destroyed.

The jspInit() and jspDestroy() methods can be overridden within a JSP page.
