I populate a hibernate persisted bean in a struts action class and store in HttpSession. Then it is forwarded to a jsp and once it is submitted - within another action I try to retrive the above bean, the session return a null value. I have checked for any intermedite code that may remove the HttpSession session or recreate it, but found none.

Could this be a known issue when using Hibernate with MySQL and Struts?
