Answer / srinivasa kumar meda
The life cycle of a servlet is controlled by the container
in which the servlet has been deployed. When a request is
mapped to a servlet, the container performs the following steps.
If an instance of the servlet does not exist, the Web container
1. Loads the servlet class.
2. Creates an instance of the servlet class.
3. Initializes the servlet instance by calling the
init method.
Invokes the service method, passing a request and response
object.

Answer / nishita
The request mapping is done in web.xml which maps URL to
the Servlet which should handle the request. When the user
hits the URL on the browser, the request is redirected to
Webserver from the code. The Web container decides which
Servlet to call based on the mapping in Web.xml. This
servlet (if it was not loaded at server startup) will first
get loaded then, it gets instantiated and then its init()
method is called. This is called only once. The
initialization happens here. After that the servlet is
ready for service, service() method is called. The service
() method can be called any number of times. Hence, without
a main method the servlet is called.

objects then it will match the url pattern in web.xml ,

no man first the constructor will run then the init()
method
which are used to intialization step likee servletconfig
then after service() method for all thread which will
create for the only on instance of servlet
what the mean is it people think that always the instance
of servlet always create when the requst for the particular
servlet but here only the one instance of servlet and the
the service method will excecute for distinct request
ao don't ever think that
note: that the constructor is default constructor you are
no able to call this constructor
so first the constructor will run
this servlet object it just a noraml object
but after the servletcofig it will be the servlet object
so the constructor will run

Since we can create managed bean by two ways as, we can define the bean name in faces-config.xml file so that page can use that OR we can write annotation on bean class so that it is automatically assign to page but I want to know which one is good programming practice ? And also mention disadvantage of other which should not prefer ... Thanking you...
