Re: SCOPE of WS-Reliable Messaging

[Aki Yoshida <sa...@googlemail.com>]

Hi vishy,
If you meant the transmission of the initial create sequence message
(the message number zero, so to speak), when you talk about the
interacting for the first time, the answer is no. The initial create
sequence message must reach node2 to begin with. If some transmission
error occurs for this message, your client gets an exception, so your
client must handle this case (either by retrying later, reporting an
error and giving up).

Once the sequence creation succeeds, the real messages will be
automatically retransmitted by the WS-RM component until the
corresponding ack messages are received. There was an issue in 2.2.9
that caused the client to get an exception when the retransmission is
performed by the WS-RM component. This issue has been fixed in 2.2.10
(ref CXF-2841).

Regards, Aki
