Cookies in Struts not updated in the first time

[vinoth kumar v]

I use the following code in action class to create cookie

 public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		String userid = ((LoginForm) form).getUserid();
		String password = ((LoginForm) form).getPassword();
		LoginControl loginControl = new LoginControl();
		String loginResult;
		String userName;
		userName = loginControl.checkUser(userid, password);
		if (userName.equals(null))

			loginResult = "failure";
		else
		{
			
			Cookie cookie = createCookie(userid,userName);
			response.addCookie(cookie);
			loginResult = "success";
		}
		return mapping.findForward(loginResult);
	}
	public Cookie createCookie(String userid,String userName)
	{
		Cookie cookie = new Cookie("userid",userid);
		cookie.setComment(userName);
		cookie.setMaxAge(172800);
		return cookie;
	}   

Struts config code

    <action name="LoginForm" path="/login" scope="request" type="action.LoginAction">
  <forward name="success" path="/Pages/User/entertask.jsp"/>
   <forward name="failure" path="/Pages/Visitor/register.jsp"/>  

entertask.jsp

 Welcome <% 
	
	Cookie[] cookies = request.getCookies();
	
	for(int i = 0 ; i< cookies.length ; i++)
	{
		if(cookies[i].getName().equals("userid"))
		{
			out.println("Cookie loop");
		out.println(cookies[i].getValue());
		}
	}
	
	%>   

When I first login through login page .
Iam successfully redirected to Entertask.jsp but cookies are not found in the first time.
(ie., It shows only welcome)

When I refresh Welcome username is displayed.

I dont know why its happening so.

Can any one please say the cause?

Is there any other way to manage cookies in STRUTS ?
