ive created a grails app and used Apache Shire plugin http://shiro.apache.org/ for security and logging in purposes.
I wanted to find out if anyone knows how I can get a list of the users who are currently logged in to the web application?
Where would this information be stored / on the servers side in a cookie or a session?
Basically i want a widget showing all the current users whom are logged in to my web application currently.
You would probably have to make a table in your app with currently logged in users (or alternatively a shared hashmap)
When your users log in you write the name to the table / hashmap. The tricky part is to figure out, when the user logs out. If the user logs out by clicking "logout" - no problem. If the users session expires you have to listen to the events fired by Shiro.
According to the Shiro website there are several events you can hook into.
