Hi
I am using EJB3 MDBs on JBoss 4.0.4 application server. Since the onMessage
method takes a lot of time to complete, I was getting the below warning,
WARN [TransactionImpl] Transaction TransactionImpl:XidImpl[FormatId=257,
GlobalId=OPGX745-FYKH3D1/1, BranchQual=, localId=1] timed out.
status=STATUS_ACTIVE
So I referred the EJB specs and as per the specs if I make the MDB to not
support transaction(TransactionAttributeType.NOT_SUPPORTED) or make it a BMT
and set the acknowledgement mode to auto-acknowledge then the message is
acknowledged once its delivered to the onMessage method and it does not depend
on the BMT transaction in the method.
I tried both the transaction not supported and the BMT but I still get the
above warning and also the message is redelivered.
Below is the code for the MDB,
@MessageDriven(activationConfig =
{
@ActivationConfigProperty(propertyName="destinationType",
propertyValue="javax.jms.Queue"),
@ActivationConfigProperty(propertyName="destination",
propertyValue="SonicJMS/Queues/datahub"),
@ActivationConfigProperty(propertyName="providerAdapterJNDI",
propertyValue="java:/SonicJMSProvider"),
@ActivationConfigProperty(propertyName="useDLQ", propertyValue="false"),
@ActivationConfigProperty(propertyName="acknowledgeMode",
propertyValue="Auto-acknowledge")
})
@TransactionManagement(TransactionManagementType.CONTAINER)
public class FeedParsingManager implements MessageListener {
@EJB
private EmailNotification emailSender;
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public void onMessage(Message msg) {
....
....
....
}
}
The onMessage method calls a stateless session bean which is a BMT. Why am I
seeing the warning message and message being redelivered?
Thanks in advance,
Rajeev
