Answer / mahesh
There are some reasons are exited they are as follows
-->GenericServlet is protocol independent where as HttpServlet is protocol dependent .
-->Due to the un implementation of http protocol GenericServlet will not provide any flexibility for the developers to specify different types of request at client mechine.
i.e. If you specify any type of request at client mechine like get,post,head.....when at server side GenericServlet able to process all this request as a normal request by calling service().
-->Due to the imlementation of HttpProtocol in HttpServlet,vl provide very good flexibility for the request at client mechine .
i.e. If we specify the request types like get,post...client mechine then HS vl execute doGet(),doPost().....respectivly at serverside.

Answer / venu bandla
because be extending generic servlet we can access only
common methods of servlet interface,and we fourcefully
access the httpservlet methods by type casting the
servletRequest and ServletResponse objects into
httpServletRequest and HttpServletResponse.so this procedure
is not recommended because of redendent code.so we are
extending the HttpServlet class
