File -> WebService -> File

Hello all,

I would like to send a request from a file to a web service, and send the WS response to a file.

I have done it with success by using a BPM, but if I don't use it, I don't receive any response of the same web service. If I look into the communication channel monitoring, I can see in the "Message Data" tab that the quality of service is Exactly Once. But the interface that I send to the receiver soap communication channel is well a synchronous interface...

Is it possible to execute this asynch -> synch -> asynch flow without a BPM?

Thanks in advance,

Gregory Paris
