Answer 1

Element : servlet-name The servlet-name element contains the canonical name of the servlet. Each servlet name is unique within the web application. Used in: filter-mapping, servlet, servlet-mapping

Element : url-pattern The url-pattern element contains the url pattern of the mapping. This is how you want your servlet class to be accessed. if you put /hello then your servlet will invoke when user access http://yourdomain/yourappname/hello
