Session auto acknowledge
Hello,
I'm trying to download messages from my QPID queue without acknowledging
them. Even though I don't acknowledge them, they still get downloaded from
the queue. How can I check is my QPID queue setup with auto acknowledge(is
there something like that)?
Thanks,
E

Yes I have, I've tried both CLIENT_ACKNOWLEDGE and DUPS_OK_ACKNOWLEDGE same
result, I consume my messages.
Any ideas?
Thanks

Have you created your JMS session with ack mode Session.CLIENT_ACKNOWLEDGE?
Thanks,

Thanks Gordon,
I found this example, it might be useful to someone else trying to do the
same thing :

In JMS you can use a QueueBrowser (see
http://download.oracle.com/javaee/1.4/api/javax/jms/QueueBrowser.html).
You can also specify 'mode: browse' in the address (see section 2.4.3.3
of
http://qpid.apache.org/books/0.10/Programming-In-Apache-Qpid/html/ch02s04.html#id2728030).

Hi Gordon,
When I say download, I probably mean "dequeue" because I'm wasn't sure which
was the right term to use here. My goal was to inspect the message content
without any de-queueing occurring.
Do you want to browse messages, i.e. see what is in the queue without
actually removing the messages? - This is exactly what I want.
Thanks,
Emir

When you say 'download' do you mean deliver or dequeue?
For acknowledged transfer, the broker will deliver a message to a
consumer. That message will not then be available to another consumer.
The first consumer can then acknowledge the message allowing the broker
to actually dequeue it permanently. However if the first consumers
session fails or closes before the message is acknowledged the broker
will make it available for other consumers.
What is it that you want to happen? Do you want to browse messages, i.e.
see what is in the queue without actually removing the messages? Or do
you want the library to automatically acknowledge, but it appears not to
be doing so?
It's not clear to me what the exact problem is.
