defining/creating messaging Queue through @ActivationConfigP

[yashendrac]

I wonder if it is mandatory to define Queues and Topics in xml in JBoss Messaging. Is there any way to make it work the way it used to in Jboss MQ, i.e. just use the @ActivationConfigProperty annotation in message consumer/MDB without defining in any xml?

In jboss MQ I don't have to define Queues and Topics in any configuration xml if I have @ActivationConfigProperty annotation in my MDB like this:

@MessageDriven(activationConfig = {
 @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
 @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
 @ActivationConfigProperty(propertyName = "subscriptionDurability", propertyValue = "Durable"),
 @ActivationConfigProperty(propertyName = "destination", propertyValue = "queue/event"),
 @ActivationConfigProperty(propertyName = "messageSelector", propertyValue = "Alarm = FALSE")})

But after moving same code to Jboss Messaging my MDB is not able to find the specified Queue in that MDB

@ActivationConfigProperty(propertyName = "destination", propertyValue = "queue/event")

I am able to resolve this problem by defining all my Queues and Topics in destination-service.xml located under deploy/messaging/destination-service.xml.

But I don't want to configure these in any xml outside of my application and would prefer using annotation in class itself.

Any suggestion would be highly appreciated.

Hi,

@ActivationConfigProperty(propertyName = "destination", propertyValue = "queue/event")

It indicates the destination that this MDB consumes messages from. The destination must exist by the time this MDB is deployed.

You can ask EJB guys for more help, as this is not part of JBoss Messaging.

Thank you gaohoward. I will post this query in EJB forum.

So probably its combination of @ActivationConfigProperty annotations defined in my MDB which make it work in JBoss 4.2.1, but why not in JBoss5.1.0 as both supports EJB3 though by default JBoss 4 uses JBoss MQ and JBoss 5 uses JBoss Messaging.
