I have very simple - probably silly too - question.
I am trying to add session variable in my application for using the userName of the logged in user.
I know if I were to use it in jsp - I could simply do session.setAttribute("userName", userName);
but here is what I am doing -
Jsp page sends information to a servlet, which queries for that user's info. Based on this I want to fetch the userName from the database and put it in a variable which should be available through out the application for the valid session. How should I be doing that?
If you think there is any other better / alternate way , then pleaase let me know (along with the above question.)
