[jboss-user] [Security & JAAS/JBoss] - Trying to get active users..

[paulaunderwood]

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.

Thanks,
Paula
