post request from jsp not received by Servlet

My servlet is not able to receive a post request from a jsp. This servlet is a load on start servlet. What could be the reason?
Code of JSP:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<HTML>
<HEAD>
<%@ page

contentType="text/html; charset=ISO-8859-1"

Code only checks for the password.

You have not implemented doPost() properly, it cannot have HttpSession as an argument.

correct implimentation of doPost is
public void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException{
}

Ya... how cud i b so so carelsss to overlook it .. thanks u both...
