Hi everyone,
Please correct me if i'm wrong.

whenevr a request for servlet comes the request is sent from web server(Apache)
to servlet engine and then it checks the deployment descriptor for configuration
information and instantiates a particular servlet accordingly and then it invokes service method
ans as per http request doGet() or doPost() is invoked.


If multiple request comes at a time, a thread is created to serve each request.
Does it instantiate servlet only once for all requests or for each request a servlet is instantiated??

I think servlet is instantiated only once when 1st request comes and then for all further requests
a new thread is started in service method....

please check and rectify the above quote.

please tell me sequence of event dat take place when multiple request comes at a time from thread point of view.

thanks in advance

Hi RabiDas,

I suggest you read up on the Servlet LifeCycle, as it contains the answers you seek.
For your convenience, the link is: http://docs.oracle.com/javaee/7/tutorial/doc/servlets002.htm

Cheers!
Chris
