What do you mean?

If you're writing a servlet, you can just implement a doGet() as well as a doPost() method in it.

In an HTML form, you can specify what HTTP method should be used to send the form to the server by using the "method" attribute on the <form> element:

<form method="post" ...

or

<for method="get" ...

Hi Abhijith,

Yes, It is possible to use doGet()as well as doPost() in a single class.

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class Test extends HttpServlet throws IOException, ServletException
{
public void doGet(HttpServletRequest req, HttpServletResponse res)
{
doPost(req,res);
} /* end of doget()*/

public void doPost(HttpservletRequest req, HttpServletResponse res)
{
String name=req.getParameter("username");
res.setContentType("text/html");
PrintWriter out= res.getWriter();
out.println(name):
} /*end of dopost*/

} /* end of class */



In your html file the declaration will be like this

form method="Get" action="dosomething".

By looking at get request, the servlet engine will call appropriate class as mapped in web.xml and invokes doget() method, which inturns calls dopost()method.

I think your doubt is clear. If not reply back .

Thanks,
Chandra

But don't be fooled by the code sample, it is possible and often even preferable for the doGet and doPost methods to do different things...

all right thanks, can you tell me what are the differences between doGet, doPost and Actionforward?

ActionForward is not part of servlets but of a proprietary framework (Struts, I believe).
