Currently both Sandesha versions (Sandesha1 and Sandesha2) do not do such a deviding of an application message into pieces. Such a functionality is not specified in the WS-RM specification. The main aim of WS-RM is delivering messages reliably from one end to another using acknoelwegement techniques. So message devision is not a must. (But it could certainly improve the performance since retransmissions will have to be done for only pieces not for the complete message). I'm not sure weather other WS-RM implementations do such a thing.

Quoting Chamikara Jayalath <[EMAIL PROTECTED]>:
I mean upper layer application message not SOAP message. I guess, SOAP message
is already at the lower layer.
I was thinking when application sends a large message to be delivered using
WS-RM, WS-RM might chunk the message into smaller messages (grouped by
sequenceID) and WS-RM sends them over SOAP one by one.
I haven't read WS-RM specification thoroughly, though.
thanks.
