message mortinoring problem

Hi ALL

scenario:

jdbc -> https

1. I use sender jdbc adaper to create a message A

2. map message A to messgae B

3. use http receiver adapter to send the message B to external https receiver.

the problem is I cannot find message B both in xsmb_moni and rmb.

Does any one know how to see the payload of message B?

Thanks
