I assume you are talking about accessing same servlet from different computers and your servlet is not implementinng Single
Thread Model.
In this case only one instance of servlet will be created. Depend upon how many requests you send to that servelt, that many number of threads will be generated. If you are sending 10 requests , 10 threds will be started by the server.
If your servlet implments Single Thread Model then picture changes little bit.
Hope this helps.
Thanks
