JCA AqAdapter on OSB - How to rollback on failure?

Question

Hi,
I have an AqAdapter (JCA resource) on OSB.
So, I generated a ProxyService that calls a BPEL BusinessService.
If the BusinessService isn't available or some fault occurs in it, how can I get a rollback on AQ?
Example:
1. JCA gets a row from AQ and send it to the ProxyService
2. ProxyService calls the BusinessService
3. BusinessService fails for some reason
4. JCA #MUST# rollback the row to AQ <--------- I mean, how can I get this 4th step done??
Please someone help me.
Thank you

Answer 1

That means it retried 5 times.
Have a look at this (extracted from: http://docs.oracle.com/cd/E12839_01/integration.1111/e10231/adptr_aq.htm). It seems to be related to what you've described:
Oracle AQ Adapter Inbound Retries
If you configure the Oracle AQ Adapter inbound retries to retry for more than 5 times by using the jca.retry.count service binding property for a retryable exception, then ensure that the queue is created with max_retries value that is greater then the value used for jca.retry.count. If nothing is specified, then the queue is created with a max_retries value of 5 which would mean that the message will end up in exception queue after 5 retries and will not be delivered to adapter for further processing. If jca.retry.count is specified with a value of 5 or less, then you do not have to change the queue max_retries property.
Use the following code to change the max_retries property when creating a queue:
begin
DBMS_AQADM.CREATE_QUEUE_TABLE ( queue_table => 'RAW_IN_QUEUE_TABLE',queue_payload_type => 'RAW');
DBMS_AQADM.CREATE_QUEUE ( queue_name => 'RAW_IN_QUEUE',queue_table=> 'RAW_IN_QUEUE_TABLE', max_retries=>1500);
DBMS_AQADM.START_QUEUE ( queue_name => 'RAW_IN_QUEUE');
DBMS_AQADM.CREATE_QUEUE_TABLE ( queue_table => 'RAW_OUT_QUEUE_TABLE', queue_payload_type => 'RAW');
DBMS_AQADM.CREATE_QUEUE ( queue_name => 'RAW_OUT_QUEUE', queue_table => 'RAW_OUT_QUEUE_TABLE');
DBMS_AQADM.START_QUEUE ( queue_name => 'RAW_OUT_QUEUE');
end;
