If your SessionManager is a "ServletContainerSessionManager", then it means that your sessions are being stored in the underlying Servlet container (e.g. Tomcat). Shiro is not responsible for their storage; it just adds a compatibility layer between that API and its own. My code shown below won't work in that case.
Your question then becomes "how do I get a list of all logged in users from my Servlet container". This SO question looks like it has an answer: http://stackoverflow.com/questions/3771103/how-do-i-get-a-list-of-all-httpsession-objects-in-a-web-application You may find other options if you poke about in the documentation or source code of your Servlet container.
