RE: Requesting WSDL Files

[Anne Thomas Manes <an...@manes.net>]

There is no standard convention for retrieving WSDL files, although many
implementations do support an HTTP GET on the service URL with "?wsdl"
appended. BEA, IBM, Microsoft, and SAP have proposed a standard protocol and
interface for retrieving all metadata associated with a service called
WS-MetadataExchange (WS-MDX). See
ftp://www6.software.ibm.com/software/developer/library/WS-MetadataExchange.p
df. Using this protocol, an application can retrieve XML Schema, WSDL, and
WS-Policy metadata.

Subject: Re: Requesting WSDL Files
 
This was discussed in the W3C architecture group, but I thought it was
interesting
to follow-up here as well.
 
I think it would be useful to be compatible with .NET 1.1 in terms of
retrieving and
requesting WSDL using the URL of the web service.
 
Eventually, this type of WSDL requesting and retrieving behaviour will need
to
finds it way into some WS-I test and/or other SOAP/WSDL interop tests, but
I think if we can fit this into AXIS 1.2 final release it would be great.
 
Thoughts?
