In the infocenter, in section "Example 4: Automatically stopping an MDB when no
exception destination is specified", it is stated that when an MDB activator is
stopped, "A JMX notification is emitted by the JCA MBean and a log entry alerts
the system administrator that the MDB has stopped"
When this happend we see in the log the following message:
ActivationSpe I J2CA0524I: The Message Endpoint for ActivationSpec
jms/act/tp_commandes (com.ibm.ws.sib.api.jmsra.impl.JmsJcaActivationSpecImpl)
and MDB Application
TitulairesPermis#TitulairesPermisEJB.jar#TestConsumerControleurImpl is
deactivated.
Fine.
Now we want to write a stateless session been with a method that will catch the
JMX notification when this event arises
Here is the code :
@Stateless
public class TestJMXImpl extends AbstractControleur implements TestJMX,
NotificationListener, Serializable {
private static final long serialVersionUID = 1L;
public void init() {
System.out.println("init");
AdminService as = AdminServiceFactory.getAdminService();
try {
ObjectName queryName = new
ObjectName("WebSphere:*,type=J2CMessageEndpoint");
Set<ObjectName> s = as.queryNames(queryName, null);
for (ObjectName objectName : s) {
System.out.println("name=" +
objectName.getCanonicalKeyPropertyListString());
as.addNotificationListener(objectName, this, null, null);
}
} catch (...) {
...
}
}
public void handleNotification(Notification n, Object handback) {
System.out.println("* Notification received at " + new Date().toString());
}
}
We call the init method and the MBean if found :
name=ActivationSpec=jms/act/tp_commandes,J2CResourceAdapter=SIB JMS Resource
Adapter,J2EEApplication=TitulairesPermis,J2EEServer=server1,MessageDrivenBean=TitulairesPermis#TitulairesPermisEJB.jar#TestConsumerControleurImpl,Server=server1,cell=pt6704Node01Cell,j2eeType=JCAMessageEndpoint,mbeanIdentifier=cells/pt6704Node01Cell/nodes/pt6704Node01/servers/server1/resources.xml#J2CResourceAdapter_1223569418301#TitulairesPermis#TitulairesPermisEJB.jar#TestConsumerControleurImpl_J2CMessageEndpoint,name=TitulairesPermis#TitulairesPermisEJB.jar#TestConsumerControleurImpl_J2CMessageEndpoint,node=pt6704Node01,platform=dynamicproxy,process=server1,spec=1.0,type=J2CMessageEndpoint,version=7.0.0.9
but the handleNotification() method is never called if we pause/resume the
activator
Nothing in the logs, nothing in FFDC...
Any idea?
