It is similar to the lifecycle of a servlet only,
They are:
jsp:init()
jsp:service()
jsp:destroy()
 The init() method initializes the servlet within jsp and 
must be called before the servlet can service any requests. 
In the entire life of a servlet, the init() method is 
called only once. 

After initialization, the servlet can service client-
requests. Each request is serviced in its own separate 
thread. The container calls the service() method of the 
servlet for every request. The service() method determines 
the kind of request being made and dispatches it to an 
appropriate method to handle the request. The developer of 
the servlet must provide an implementation for these 
methods. If a request for a method that is not implemented 
by the servlet is made, the method of the parent class is 
called, typically resulting in an error being returned to 
the requester
. 
Finally, the container calls the destroy() method which 
takes the servlet out of service. The destroy() method like 
init() is called only once in the lifecycle of a Servlet.

jsp life cycle:
===============
1.Page translation - automatically translate the .jsp file 
in .java(servlet)file
2.Compilation   - automatically compile the .java(servlet) 
file and create .class file .
3.Loading - load the compiled servlet into container.
4.Create instance - create instance for loaded servlet 
(.java)
5.call jspInit method. (call only one time)
6.call _jspService method
7.call jspDestroy method.(call only one time)
