See the JMX message org.jboss.system.server.Server.START_NOTIFICATION_TYPE.
The MBean would look something like this:
import org.jboss.system.server.Server;
import javax.management.Notification;
import javax.management.NotificationFilter;
import javax.management.NotificationListener;
import org.jboss.system.ServiceMBeanSupport;
public class ServerLoadDetector extends ServiceMBeanSupport
implements ServerLoadDetectorMBean,
NotificationFilter, NotificationListener
{
boolean state = false;
//
// MBean read only attribute
// @jmx:managed-attribute
//
public boolean isStarted()
{
return state;
}
//
// NotificationFilter, NotificationListener Implementations
//
public boolean isNotificationEnabled(Notification n)
{
return (Server.START_NOTIFICATION_TYPE.equals(n.getType()));
}
public void handleNotification(Notification n, Object handback)
{
// set an attribute that can be remotely introspected
state = true;
}
}

The started field could be added as an attribute on the
ServerImplMBean mbean.
Actually there is no way to know,
though it is possible to know when the server starts because it sends a JMX
notification at this moment.
