Subject: Re: Value not persisting in domain object

Hi Paul,

As per Oracle :
*invalidate<http://docs.oracle.com/javaee/5/api/javax/servlet/http/HttpSession.html#invalidate()>
*()
          Invalidates this session then unbinds any objects bound to it.

My target is to remove only the cart object.

Thanks,
Srineel
