Subject Re: Camel JMS re-delivery on failure
Date Mon, 18 Jul 2011 21:37:40 GMT
Hi,

Rollback of transactions all the way back to the Queue happens only if the
ActiveMQ consumer/producer that write to the queue/topic use a Transacted
session in ActiveMQ.

When you create a connection factory, you need to set a Transaction Manager
and a associated a Transaction against the JMS consumer. When the JMS
consumer picks up the message and the session is transacted, then in case of
failure to perform the route and in case of exception the message will
reappear on the queue from where the consumer picked up the message...

Please find a working spring sample of how to create a transactional JMS
Ccomponent below
https://svn.apache.org/viewvc/camel/trunk/components/camel-jms/src/test/resources/org/apache/camel/component/jms/tx/AbstractTransactionTest.xml?view=co&content-type=text%2Fplain
https://svn.apache.org/viewvc/camel/trunk/components/camel-jms/src/test/resources/org/apache/camel/component/jms/tx/AbstractTransactionTest.xml?view=co&content-type=text%2Fplain


(Note that there are 2 configurations shown) in the link above.

As for then using the transactional JMS component, please find a working
transactional camel route below
https://svn.apache.org/viewvc/camel/trunk/components/camel-jms/src/test/resources/org/apache/camel/component/jms/tx/XMLQueueToProcessorTransactionTest.xml?view=co&content-type=text%2Fplain
https://svn.apache.org/viewvc/camel/trunk/components/camel-jms/src/test/resources/org/apache/camel/component/jms/tx/XMLQueueToProcessorTransactionTest.xml?view=co&content-type=text%2Fplain

 
Cheers,

Ashwin...
