I have this in a file called GetActiveUsersAction.java.. | MBeanServer server = (MBeanServer) MBeanServerFactory.findMBeanServer(null).get(0); | String jaasMgrName = "jboss.security:service=JaasSecurityManager"; | ObjectName jaasMgr = new ObjectName(jaasMgrName); | Object[] params = { "SecurityPolicy" }; | String[] signature = { "java.lang.String" }; | activeUsers = (List<User>) server.invoke(jaasMgr, "getAuthenticationCachePrincipals", params, signature); | My list always comes back with a 0 length.. Am I missing something? Also, what exactly does this return.. I know a list.. but what information about the user does it return? I haven't been able to find an explanation other than to use the code above. We would like to have a page that will show all the users logged into our system.
