RE: [sca-bindings] ISSUE 19: Web Service binding should allow #wsdl.binding with reference targets

The latest draft of the spec, in PDF, has
lines 82 and 83, which seem to be what we are talking about (not lines 53 and
54).

 

The context is this:

 

 

/binding.ws/@wsdlElement – optional
attribute that specifies the URI of a WSDL element. The use of this attribute
indicates that the SCA binding points to the specified element in an existing
WSDL document. The URI can have the following forms: 

 

...

o Binding: 

<WSDL-namespace-URI>#wsdl.binding(<binding-name>)

In this case, the
identified WSDL binding must have an equivalent PortType with the SCA service
or reference. In this case the endpoint address URI for the SCA service or
reference must be provided via the URI attribute on the binding. 

I

It doesn’t seem right to me to
change the last sentence to: “The endpoint address URI for an SCA service
MUST be provided as the URI attribute on the binding, and the endpoint address
URI for an SCA reference MUST be provided either as the URI attribute on the
binding or by the endpoint address implied by a reference target URI or wire
target URI.”

 

In the case of services, I believe that we
should allow the URI to be computed based on the defaulting rules.

 

In the case of references, I think the
original point of the text was that the URI attribute needs to be set, since it
will be pointing to something that is outside
of SCA and won’t be using SCA’s wiring mechanisms.  After all,
if you are using SCA wiring, you have no business specifying WS binding details on the client side.

 

One final note, I think the first sentence
should replace the “equivalent” with “conforming”.

Subject: Re: [sca-bindings] ISSUE
19: Web Service binding should allow #wsdl.binding with reference targets

 

On last week's sca-bindings call, I took an action to
post an updated proposal for the resolution of this issue, based on some words
posted by Michael Rowley in the chat room.  Here's my proposal.

In
the Web Service binding spec, lines 53 and 54, replace "...the endpoint
address URI for the SCA service or reference must be provided via the URI
attribute on the binding" by "the endpoint address URI for an SCA
service MUST be provided as the URI attribute on the binding, and the endpoint
address URI for an SCA reference MUST be provided either as the URI attribute
on the binding or by the endpoint address implied by a reference target URI or
wire target URI".
