> 1) Is WSDL a Microsoft-only thing?
WSDL is a proposal that has been submitted to the W3C, but not yet adopted.
While over two dozen companies signed the submission, Microsoft and IBM seem
to
be the leading proponents.
> 2) How does one generate these files?
There are a variety of tools out there, from a variety of sources. The
IBM Web Service Toolkit is an obvious starting place, but there are others.
And, in case it isn't obvious, Microsoft Visual Studio .Net generates them.
However, I have yet to have any luck with any of them parsing the
myservices.wsdl
file from Microsoft (including the wsdl utility from Microsoft).
> 3) Are these files always needed when offering a web service via SOAP?
In theory, no.
However, any web service being developed using Microsoft tools is likely to
use them. When things settle down, so that tools and wsdl files are all
mutually compatible, then it will help with web service development.
