Why do we go for GenericServlet and when do we go for HttpServlet?As far as I know ,HttpServlet is used if the protocal is HTTP,are there any other reasons to select among them?

A Servlet in genereral , is an instance of a class which implements the javax.servlet.Servlet interface. Most Servlets, extend one of the standard implementations of that interface. GenericServlet implements the Servlet and ServletConfig interfaces.GenericServlet may be directly extended by a servlet.

public abstract class GenericServlet
extends java.lang.Object
implements Servlet, ServletConfig, java.io.Serializable



HttpServlet is a subclass of GenericServlet

public abstract class HttpServlet extends GenericServlet
implements java.io.Serializable



As you see the term Generic and Http, Generic servlet is not protocol specific, it works for all protocols. But HttpServlet is specifically used for handling HTTP requests
