I would like to get the list of users online. In this tutorial I could see the code that is used to get the count of users online.
I think I need to have a list that gets and stores the the usernames in sessionCreated(HttpSessionEvent event) and then display this list.
Please suggest if this is the correct method or if there is there a better way to do this.
This is How you have to keep track of the User Sessions.
