[JBoss Portal] - Get online users
by ameo
Hello,
I want to get the current online users that logged in portal. The reason is that I want to verify during the login if a user is already logged, and if so, to give him an appropriate answer.
I have see the sample portlet that uses the UsersActivityStatsService.
Cause I use facelets and jsf, I tried to get the UsersActivityStatsService with the following method:
| private UsersActivityStatsService getStatsService() {
| UsersActivityStatsService activityService = null;
| try {
| MBeanServer mbeanServer = MBeanServerLocator.locateJBoss();
| activityService = (UsersActivityStatsService) MBeanProxy.get(UsersActivityStatsService.class, new ObjectName(
| "portal:service=Module,type=UsersActivityStatsService"), mbeanServer);
| } catch (MBeanProxyCreationException e) {
| logger.error("could not obtain a proxy for User Activity Statistics Service", e);
| } catch (MalformedObjectNameException e2) {
| logger.error("object name to obtain User Activity Statistics Service is wrong", e2);
| }
|
| return activityService;
| }
|
So I get the service, but if I call the method getActiveUsersNames I get no results.
| UsersActivityStatsService uass = getStatsService();
| Set users = uass.getActiveUsersNames(18000000);
|
Could you tell me, how to use this service correctly ?

[Installation, Configuration & DEPLOYMENT] - starting, stoping web application from MBean in 5.0.1.GA
by mikala
Hello !!!
I try to control web application - stop(), start() (deploy,undeploy) - on JBOSS 5.0.1.
I can call stop() or start() methods on jboss.web.deployment:war=/www MBean in jmx-console, my www.war application starting or stoping.
I wrote my MBean which calls start(),stop() methods from jboss.web.deployment:war=/www jboss MBean:
| @Service(name = "WebAppController", objectName = "www:service=WebAppController")
| @Local(WebAppControllerLocal.class)
| @Remote(WebAppControllerRemote.class)
| @Management(WebAppControllerManagement.class)
| public class WebAppController implements WebAppControllerLocal,
| WebAppControllerRemote, WebAppControllerManagement {
| private static Logger log = Logger.getLogger(WebAppController.class);
|
| public void startWebApp(String app) {
| log.info("starting www applications ...");
| try {
| MBeanServer server = (MBeanServer) MBeanServerFactory
| .findMBeanServer(null).get(0);
| ObjectName name = new ObjectName("jboss.web.deployment:war=/" + app);
| server.invoke(name, "start", new Object[0], new String[0]);
| } catch (Exception e) {
| e.printStackTrace();
| }
| }
| public void stopWebApp(String app) {
| log.info("stoping www applications ...");
| try {
| MBeanServer server = (MBeanServer) MBeanServerFactory
| .findMBeanServer(null).get(0);
| ObjectName name = new ObjectName("jboss.web.deployment:war=/" + app);
| server.invoke(name, "stop", new Object[0], new String[0]);
| } catch (Exception e) {
| e.printStackTrace();
| }
| }
| public void create() throws Exception {
| log.info("creating service");
| }
| public void start() throws Exception {
| log.info("starting service");
| }
| public void stop() {
| log.info("stoping service");
| }
| public void destroy() {
| log.info("destroying service");
| }
| }
|
When I try to run stopWebApp("www") and startWebApp("www") from jmx-console I have exception:
