This statement shuts that debate down. > Indeed. I do remember the debate and the motivation behind the text. I'm focusing on what an invocation means in the WSDL world. An invocation involves calling exactly one method on exactly one WSDL port. If you used two different ports, then you are involved in two different invocations. If you wanted to do some kind of fan-out, then you would create a WSDL binding and associated port which allows you to specify multiple URLs or a multicast address (in the case of UDP) or something like that. I suppose we can put in non-normative text that explains this, but I'm not convinced that (1) we need a normative sentence, (2) the current wording is meaningful > I don't see why you think its untestable.

I agree it is testable with our tests, where we have control over the invoker and the invokee. I was thinking of the transport/messaging layer and testing at that level, where you can't distinguish between two separate invocation and a single invocation being fanned out on the reference-side. -Anish -- > Dave Booz > STSM, BPM and SCA Architecture > Co-Chair OASIS SCA-Policy TC and SCA-J TC > "Distributed objects first, then world hunger" > Poughkeepsie, NY (845)-435-6093 or 8-295-6093 > e-mail:booz@us.ibm.com > > > |------------> > | From: | > |------------> > >--------------------------------------------------------------------------------------------------------------------------------------------------| > |Eric Johnson<eric@tibco.com> | > >--------------------------------------------------------------------------------------------------------------------------------------------------| > |------------> > | To: | > |------------> > >--------------------------------------------------------------------------------------------------------------------------------------------------| > |Anish Karmarkar<Anish.Karmarkar@oracle.com> | > >--------------------------------------------------------------------------------------------------------------------------------------------------| > |------------> > | Cc: | > |------------> > >--------------------------------------------------------------------------------------------------------------------------------------------------| > |OASIS Bindings<sca-bindings@lists.oasis-open.org> | > >--------------------------------------------------------------------------------------------------------------------------------------------------| > |------------> > | Date: | > |------------> > >--------------------------------------------------------------------------------------------------------------------------------------------------| > |02/10/2010 08:46 PM | > >--------------------------------------------------------------------------------------------------------------------------------------------------| > |------------> > | Subject: | > |------------> > >--------------------------------------------------------------------------------------------------------------------------------------------------| > |Re: [sca-bindings] BINDINGS-113: What does BWS20006 mean? | > >--------------------------------------------------------------------------------------------------------------------------------------------------| > > > > > > Logged as: http://www.osoa.org/jira/browse/BINDINGS-113 > > -Eric. > > On 02/10/2010 04:02 PM, Anish Karmarkar wrote: >> Title: What does BWS20006 mean? >> >> Spec: WS Binding >> >> Description: >> BWS20006 says -- >> "When an invocation is made using an SCA reference binding with the >> wsdl.service form of wsdlElement, the SCA runtime MUST use exactly one >> port from the set of available ports for the reference (with port >> selection on a per-invocation basis permitted)." >> >> This is, at the very least, untestable.
