redirecting to a new page when session expires

Hello All
I am having a problem while redirecting in struts .When my session expires i redirect to the login page.i.e
if(session == null || session.getAttribute("userId") == null){
return mapping.findForward("login");}
and in my struts_config.xml,i have included
<forward name="login" path="login.jsp" redirect="true"/>
But the problem is when the session expires,the login page is being displayed within the page as a inner frame but not as a fresh new page.Can please suggest a solution to this?
Thanks

2. Code the following somewhere in the <head> portion of the page:

If the parent variable is not null, that means the current page is being displayed in a frameset. This code will replace the frameset with the login page.

After trying it out, the code in my previous post does not work, but this code does:
