service()method the GenericServlets service() method is
declared as abstract.But the Generic Servlet is not
implementing keeping the HttpSErvers in mind. Methods we
have in this class are
init()
log()
service()
While implementing the HTTP Servlet the service() method is
already implemented .service()method of HTTP sevlet is
declared as protected.the HTTPServlet is implementing
keeping the HttpSErvers in mind. Methods we have in this
class are
doGet(),doDelete(),doPost()
