request is not going into onSubmit

[indu iyengar]

Hi
am developing a login application with mvc. the request is straightly going to Loginsuccess page without entering into onSubmit() method..
my code in student-servlet.xml

<bean name="/login.htm" class="controllers.Login1">
    <property name="formView" value="Loginform"></property>
    <property name="successView" value="LoginSuccess"></property>
    <property name="commandName" value="student"></property>
    <property name="commandClass" value="com.std.CheckStudent"></property>
</bean>    

code in Login1 Controller

public class Login1 extends SimpleFormController
{
   private static final Logger logger = Logger.getLogger(Login1.class);
   	public Login1()
    {
	   	setCommandClass(CheckStudent.class);
     }
  
  protected ModelAndView onSubmit(HttpServletRequest request,HttpServletResponse response,Object command,BindException errors)throws ServletException                     
  {
	  BasicConfigurator.configure();
	  logger.info(" *********** in submit *************");
	  
	  String id = request.getParameter("stid");
	  String pw = request.getParameter("stpw");
	  HttpSession session = request.getSession();
	  session.setAttribute("stid",id);
	  return new ModelAndView("LoginSuccess");
	   
  }
}
