Servlet LifeCycle

LifeCycle:  Servlet Creation to Termination:

-- Servlet is intialized by calling the init() method.  Init() method called only once when first created

-- Client requests processed by service() method.  Each request resulted a new thread calling service() method.  Service method checks the request type (GET, POST, PUT, DELETE) and call doGet, doPost, doPut or doDelete() methods.

-- Servlet is termincated by desctroy() method

-- Finally, garbage collected by the JVM garbage collector
