Hi,
The main purpose of message processors are to support store and
forward messaging patterns.
In your scenario what you are trying to do is send the responce
comming back to the original client.which we do not support.
Basically idea is to support in only invocations.we provide a way to
handle the responce by using a responce sequence
but that is for the purpose of handling the processing of the
responce.you can't send the response back to the original client.
Message Forwarding prosessor will gurentee the delivey between esb and
back end service.
But it's not intended for support end to end atomic transaction
between client to backend service via esb.

Hi All,
We are trying to implement Guranteed Delivery in one of our project.
For doing so we are using ScheduledMessageForwardingProcessor. We
are using request-response messaging pattern. To get the response we
have used message.processor.reply.sequence property. We are able to
log the response payload in the response sequence. But on trying to
send the response back to the client we are getting the following
error.

We are using the following sequence as the response sequence,
<sequence name="ReplySequence" trace="disable">
<log/>
<header name="To" action="remove"/>
<property name="NO_ENTITY_BODY" scope="axis2"
action="remove"/>
<property name="RESPONSE" value="true" scope="default"/>
<xslt key="conf:/users/wcf2ctms.xslt"/>
<log level="full"/>
<send/>
</sequence>
Can anybody point us out where we are going wrong? Do we need to set
any property in the response. Because the SOA headers seems to be
fine.
We have tried even without removing the 'To' still we are getting
the same error.
I'm attaching the entire synapse definition herewith.Please let us
know if anybody has any clue about this?
Thanks,
Debarshi
