Sending message with delay

[ssmyka]

Hi,

We need to send messages with specified delay. The message should not be visible for the consumers before the delay time.

In weblogic we used the vendor specific API for this: weblogic.jms.extensions.WLMessageProducer.setTimeToDeliver(n).

Is there something similary for JBoss?

Thanks,
Szymon

I'm not aware of any initial delay.

But you can set the redeliver delay:

<!-- Queue where APILinkProxy messages are sent to -->
<mbean code="org.jboss.mq.server.jmx.Queue"
 name="jboss.mq.destination:service=Queue,name=myqueue">
 <depends optional-attribute-name="DestinationManager">jboss.mq:service=DestinationManager</depends>
 <attribute name="ReceiversImpl">org.jboss.mq.server.ReceiversImplArrayList</attribute>
 <attribute name="RedeliveryDelay">1000</attribute>
 <attribute name="RedeliveryLimit">3</attribute>
 </mbean>

So, I guess you could do an immediate NACK after receiving the message the message the first time. (You can check using the msg.getJMSRedelivered() method), and set a redeliver delay...

Also take a look at:

This might help
