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
