Subject: RE: [wsbpel] Issue - 77 - Why I think a no vote is appropriate


Title: Message
Re-working the WSDL has always seemed to me the least worst solution.
 
Consider how things might appear to an end-user, confronted with the wsdl his friend wrote the previous year, and now equipped with BPEL (and some helpful documentation):
    - if we've added the unattached message capability to BPEL, the user reads about how to work out from the binding what he can access from BPEL
    - if we haven't, he reads about how to work out from the binding what the "pure abstract" WSDL would be
 
I'd expect the thinking involved to be very similar - in the first case, the user has to work with a kind of virtual "pure abstract" WSDL, since he knows (from the binding) which business-process-relevant unattached messages are actually involved with which operation. Writing it out would be safer and clearer - and perhaps an easier target for tools.
 
 
If we don't change what is in BPEL, should we have a brief non-normative note pointing out that re-working the WSDL defintiion is occasionally necessary.

Yaron,

    Well said. I don't think we are going to find an elegant solution to this issue lurking in the wings, but your recommendation is as close as we will come to one.

Cheers,
-Ron

I have a lot of sympathy for Ugo's position but as discussed previously (

<http://lists.oasis-open.org/archives/wsbpel/200311/msg00107.html> ) it is
possible to deal with the edge case WSDLs that have been discussed by
creating altered versions of them and then feeding the altered versions to
the BPEL engine. While I agree that this is not very elegant it does seem
like a reasonable work around given that the scenarios under discussion are
extreme edge cases. As such I recommend that we declare the problem solved
and vote no on 77.
 
    Just my two Euros,
 
        Yaron
