RE: [wsbpel] Issue - 77 - Under specified operation definitions

[Francisco Curbera <curbera@us.ibm.com>]

Hi Ugo,

I would not agree with that conclusion. The way WSIF would support your
example in issue 77 is through a binding module (called a "provider" in
WSIF) that understans and takes care of the header as declared by the WSDL
binding. The application using WSIF to access the service does not see the
header message or anything else in the binding.  Same thing with non-SOAP
bindings. This is a key design point because otherwise you loose your
ability to use different access channels with different QoS characteristics
to reach the same service (different bindings). It also results in a
cleaner programming model.

Regards,

Paco

I conclude from this that my WSIF example seems appropriate for this
discussion. WSIF would be able to support a case like the one I gave for
issue 77, and it would be able to map the "Header" abstract message to any
particular binding I want to express (including, but not limited to, SOAP -
in particular, bindings that don't even have the concept of a header)). Is
that correct?

WSIF is a set of bindings for Java and J2EE; it doesn't extend WSDL in any
non-standard way that I am aware of. WSIF "understands" WSDL files that use
those bindings. The message model is plain WSDL 1.1.

            So are you saying that WSIF can only process a subset of all
            the legal

      (according to WSDL 1.1) WSDL files? (Please notice that I am not
      talking
      about adding any extension at the abstract level - just supporting
      what is
      allowed by WSDL 1.1)

                        Just curious: does WSIF allow you to define

                  messages that are not
                  part of an abstract operation?

                        Ugo

                  No it doesn't; WSIF only adds additional bindings to
                  WSDL,
                  not anything
                  at the abstract level.
