refresh the jsp page(ajax)

I've done a login application using Ajax. I wrote jsp page having sign in option. when i click the sign in,pop up window opened. pop up window contains login form,in which we enter the our details.whenever i submit the details,it has successfully login and the pop up is closed.
my intension is when i click the submit button,after login with user details then pop up window has to close and jsp page has to refresh.
how can i solve this problem

Thanks,
