What are the lifecycle methods of Servlet?
The interface javax.servlet.Servlet, defines the three life-cycle methods. These are: public void init(ServletConfig config) throws ServletException public void service( ServletRequest req, ServletResponse res) throws ServletException, IOException public void destroy() The container manages the lifecycle of the Servlet. When a new request come to a Servlet, the container performs the following steps. 1. If an instance of the servlet does not exist, the web container * Loads the servlet class. * Creates an instance of the servlet class. * Initializes the servlet instance by calling the init method. Initialization is covered in Initializing a Servlet. 2. The container invokes the service method, passing request and response objects. 3. To remove the servlet, container finalizes the servlet by calling the servlet’s destroy method.
