Hi Asankha,
Yes, I mean sending a one way fire and forget client request to Synapse.
With reliable messaging enabled this does work, yes.
But I am experiencing problems when sending a one way fire and forget client
request without reliable messaging enabled.
I get the following stacktrace, after the message has been received by the
service that Synapse calls:
[HTTPWorker-1] ERROR Axis2Sender - Unexpected error during Sending message

This stacktrace to me looks like Synapse is trying to consume a response from
the service that is not there.
Therefore the incoming message input stream is null.
Do you know why this error is returned?

Tijs
