J2EE: SERVLET: What is Servlet Interface?


Interface javax.servlet.Servlet is that interface which defines the ServletLife Cycle methods. So, all servlets must implement this interface, either directly or by extending a class which implements this interface. Instead of directly implementing the Servlet Interface, a servlet can also extend Class GenericServlet (which implements Servlet Interface), or can extend HttpServlet Class (which extends the GenericServlet class).



Methods of Interface Servlet:
  • init(ServletConfig config) : Called by the Web Container to initialize a servlet. Here, config  is a ServletConfig object containing the servlet's configuration and initialization parameters      
  • service(ServletRequest req, ServletResponse res) : Called by the Web Container to allow a servlet to respond to a request. Here, req is the ServletRequest object that contains the client's request and res is the ServletResponse object that contains the servlet's response.

  • destroy() : Called by the Web Container to clean up a servlet’s service.

  • getServletConfig() : Return a ServletConfig object, which contain the initialization parameter and startup configuration of a servlet.

  • getServletInfo() : Returns a string containing the details of a servlet, like author, version and copyright.
