What difference between genricServlet and httpServlet


public abstract class GenericServlet extends java.lang.Object implements Servlet, ServletConfig, java.io.Serializable
  • GenericServlet defines a generic, protocol-independent servlet.
  • GenericServlet gives a blueprint and makes writing servlet easier.
  • GenericServlet provides simple versions of the lifecycle methods init and destroy and of the methods in the ServletConfig interface.
  • GenericServlet implements the log method, declared in the ServletContext interface.
  • To write a generic servlet, it is sufficient to override the abstract service method.
javax.servlet.http.HttpServlet
Signature: public abstract class HttpServlet extends GenericServlet implements java.io.Serializable
  • HttpServlet defines a HTTP protocol specific servlet.
  • HttpServlet gives a blueprint for Http servlet and makes writing them easier.
  • HttpServlet extends the GenericServlet and hence inherits the properties GenericServlet.
