I have a process wherein I submit to an Action class from my jsp page, I write to the database and return the newly created database entry, create a new HttpSession and put the newly created entry in the Session as an attribute and forward to another jsp page. I do some changes in the second jsp page and write some more information to the database. Now the question here is that, I will create a new HttpSession in the first submit and put that as an attribute in that Session. Now when I call another action class from my second jsp page, I will get the Session attribute from the request and check if that attribute is not null and if it it not, then I will use the values read from that attribute. Well, the question that I have is how would I get the same Session object that I have created in my first jsp submit??
If you get the current request's session you'll get *the* session: HttpServletRequest.getSession(boolean). Also note that unless you've explicitly disabled it, visiting any JSP page, directly or via an action, a session will have already been created.
You almost never have to create your own HttpSession locally.
