Hi all,
I'm using the resend exchange feature of ServiceMix (method
resendExchange of JBIContainer) and I have the following problem: I have
a very simple SA composed of
HTTP BC -> Transformer SE -> Screen BC
I saved the exchange sent from the HTTP BC to the Transformer SE, and
later I resent it.
What happens is that the exchange is sent (with status Active), the
transformer elaborates it and send another exchange to the Screen BC,
and finally the Transformer SE send the Done exchange to the HTTP BC.
And now the problem: when the HTTP BC receives the Done exchange, it
says "what is this ?? ah, no no no, this is not my exchange..." with
this exception:
ERROR - HttpComponent - Error processing exchange InOnly[

In fact, it's right: it didn't send that exchange because I resent an
old exchange, but....
Is there a way to avoid this problem ? The resend feature is very useful
for me because it allows to restart a failed SA in the middle, and not
from the beginning, that in some cases can be a problem because the
previous components may have changed the database (for example).
A listener could intercept the Done exchange for the HTTP BC and block
it (for example) ?
Do you have any idea ?
Thanks
