java - View login status real time -


I am on a Java project and I meet the problem with the view login user. My client wants to see the login time in real time, I have a solution (when the entry, status of change in DB and status updates in the user table, this is not real time, my client is updated when there is an event. ..), I know that this is a bad idea, can anyone give me some solution for this matter?

Thank you.
