see HttpSessionListener it will guide you through.
Use HttpSessionListener to listen for sessions being created or removed. When one is, query the database for all users with a "1" in the online field. Update the data to a hashmap that is stored in a ServletContext attribute (so it is accessable by the entire web app).
