I am trying to get the redelivery feature working. I am currently using 2.3.0.CR1 and in stand-alone/non-clustered mode.

I have setup Hornetq-configuration.xml as

<address-setting match="jms.queue.AC_NOTIFICATION_Q_1">

               <redelivery-delay>3000</redelivery-delay>

                <max-delivery-attempts>3</max-delivery-attempts>

</address-setting>

Code:

Setup :

sessionFactory.createSession(true, false);

consumer = session.createConsumer(new SimpleString(qname));

consumer.setMessageHandler(this);

session.start();

Handler :

public void onMessage(final ClientMessage message) {

        HornetQBuffer readBytes = message.getBodyBuffer();

        byte[] data = new byte[message.getBodySize()];

        readBytes.readBytes(data);

        try {

               if ( false )

                 message.individualAcknowledge();

        } catch (Exception e) {

            logger.error("Unexcepted Exception while consuming message : " + e.getMessage());

        }

    }

I want to use sessions client acknowledge and message.individualAcknowledge().

I get the message only once and since I don't acknowledge the message I should have it redelivered again in 3 seconds as per the configuration in hornetq-configuration.xml.

I tried this using JMS API too and still redelivery does not happen. Using Jms API I create session using

connection.createSession(false, Session.CLIENT_ACKNOWLEDGE);

This not work either.

BTW, does redelivery work only with transacted sessions?

Thanks for your help.
