Answer / chadnra kunchala

well, there are two service methods we have.
one is, public service()
second is protected service()

when ever a browser sends a request to server, first it
invokes public service(ServeletRequest req, ServletResponse
res) throws ServletException, IOException
{ }
after calling public service method it invokes the protected
service() method like the following
public service(ServletRequest req, ServletResponse res)
throws ServletException, IOException
{
HttpServletRequest hreq = (HttpServletRequest)req;
HttpServletResponse hres = (HttpServletresponse)res;
protected service(hreq, hres);
}
then,
The protected service() method will idendtify the
requested method whether it is GET OR POST OR PUT like that
, then it invokes the correspondin method like doGet()or
doPost() or doPut() like that..

recommended to override doGet() or doPost() or and..... so
on, not service method()..

a new thread.service() method accepts ServletRequest and
ServletResponse objects as parameters.ServletRequest object
contains client requests.It contains data sent in
name/value pairs.

ServletResponse object is used to send the respose to the
client.

public void service(ServletRequest req,ServletResponse res)
throws ServletException,IOException
