Servlet is instantiated by servlet container by calling
method Class.forName(Servlet class name).newInstance();
First of all Servlet Container looks into the
deployment descriptor(web.xml) .It looks the definition of
Servlet.And Than instantiate it by calling
Class.forName(Servlet class name).newInstance();

Answer / suraj kumar
The servlet is controlled by the container in which the servlet has been deployed. When a request is made to a servlet, its mapping is searched in web.xml. If mapping found then the container performs the following steps.
a.If an instance of the servlet does not exist, the Web container loads the servlet class.
b.Creates an instance of the servlet class.
c.Initializes the servlet instance by calling the init method

Answer / nishidh soni
Servlet is initialized by two ways...
1)By initializing the constructor:-but in the initial version of JDK 1.0 constructor can not be initialized for the dynamic page loading so that init() method for the servlet comes into the picture.
2)By invoking the init() method:-This init() method is invoked by the servlet container at it is invoked once per servlet and it uses the ServletConfig as a object for the initialized parameter.and the it is like
init(ServletConfig config)
{
.....
}

Answer / harikumar
if we deploy our web root dir in webapps , then we call url
from the browser.
then after loading , it calls the init() method first.
There r two tow init() methods(first init() & second init
()).
