Subject: RE: [wsbpel] Issue - 236 - Clarification on CorrelationViolation for Outbound Messages
Hello,
Well actually yes the issue is about somthing else, however
the change to the appendix looks misleading to me, since it suggests that in the
2-way-invoke case a response will be received even if a violation is thrown. Or
is this intentional?
And also we had a discussion what "fault thrown" means, and
we should state if or if not we want to say anything about the partner, maybe
"if the binding allows responses/aknowledgement to response-messages, then the
BPEL system faul may/may not be dispatched to the partner"
Anyway, I think this is another viewpoint
here:
Thrown when
the contents of the messages that are processed in an invoke, receive, or reply
activity do not match specified correlation information. If the fault is in
the context of an inbound message, then the message MUST not be received by the
process, the invoke or receive
throws a fault to the BPEL process. If the fault is in
the context of an outbound message, then the message MUST NOT be dispatched
OUT by the process.
Gruss

Bernd, Thanks for the
feedback! Maybe I was not clear
enough or I am miss-understanding you, but this issue (236) is related to the
outbound messages only and not at all to the incoming reply (‘in’-constraint) of
a request-reply invoke. What might be confusing
is that as part of spec text for this issue, I wanted to update the appendix
definition of a correlationViolation fault and I noticed that as it was it did
not completely reflect the latest change to section 14.3 regarding the incoming
reply of a request-reply invoke, thus I also moved over this explanation to the
appendix. In another words, the
phrase ‘If the fault is in the context of an inbound message,
then the message MUST not be received by the process, except in the case of
an invoke activity with a request/reply
operation.’ is
meant to just reflect what currently _already_ is specified in section
14.3. Would it help if I
change the proposed text to: Thrown when the contents of the messages that are
processed in an invoke, receive, or reply activity do not match specified
correlation information. If the fault is in the context of an inbound
message, then the message MUST not be received by the process, except in the case of
an invoke activity with a request/reply operation. If
the fault is in the context of an outbound message, then the message MUST NOT be
dispatched OUT by the process.
Thanks, Alex From:
Eckenfels. Bernd [mailto:B.Eckenfels@seeburger.de] Hello
Alexandre, just a minor note, i
think we had this already, but since we want to change the wording here: if a
reply is received on a two way invoke, and the reply violates the correlation,
then the message will not be dispatched (this issue) and a correlation violation
will be thrown by the invoke - however, it is not required (but possible?) to be
also send to the web service who originated the
response? I also think the below
proposed changes to the appendix are not correct, or do you really want to
receive the reply if it violates the
"in"-constraint?

236 - Clarification on CorrelationViolation for Outbound

Status:
received Specification does not clarify what happens when a
invoke activity fails with bpws:correlationViolation fault for the out message
(i.e. pattern out or out-in). Is the request actually send out or
not? In the case
of the correlationViolation failure for the outbound message, the message is not
dispatched out. - In

by:
- In
Appendix A. Standard Faults, replace the paragraph:
