We have a standard J2EE/Struts internal web application that has been used in production for many years. We save many Java objects into HttpSession then retrieve them for one request to another. It works most times (maybe 99.9%) but occasionally it just can’t find any Java objects we saved in session for no reason so our application will crash. It looks like session is lost when it happens.
