RE: [JBoss-user] Message to User about JBoss Startup Complete
Hi Fred,
Really
sorry about the delayed response...
There were
some other priorities to be covered, before this.
What I
understand from this is to deploy the following as an MBean and then try
to access the MBean's isStarted() at regular intervals.
If this is
the case, how can I lookup this MBean, since I dont see nay JNDI
names(referring to the documentation example for MBean.)
Plus the service will be only deployed when the JBoss server itself
start's right?
Can you please specify the jboss-service.xml for this service?
Thanks
Muraly

The MBean would look something like this:

import javax.management.NotificationFilter;
import javax.management.NotificationListener;
import org.jboss.system.ServiceMBeanSupport;
public class ServerLoadDetector extends ServiceMBeanSupport

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.
