I must ask help with sessions because I am making a system that has servlet in charge to receive a form from a page jsp, which one you see successfully entered the form, I need to leave it entered within the same page jsp, in a listing but it leaves to me very expensive to make updates towards SAP, that is the one who has the entered data. So, I need to keep that information that I show in jsp in the session of the user.
To save data in the session you use in the servlet
you collect it with:
request.getSession().getAttribute("name of object");
