2)How webserver is able to create servlet instances.
3)How my servlet is getting loaded into the servlet container memory?,what is mechanism that Vendor use to call my servlet and what is the HttpServletInterface Role in all this.
4)Though i never do anything with service(),how this method is getting called.How service() is getting executed.
