Re: Microsoft .NET frontending IBM i

Well said.
I will also add that many have no idea when given a WSDL.  I often hear
"OK.  I generated my code from your WSDL.  It does not work.  What do I do
now?"  This is almost always from .NET clients.  This is not a dig (well,
maybe it is) but it's the truth.

We use the simple XML approach (from a server perspective) for our IBMi web
services. We have also (as previously alluded) refer to them as RESTful.
The fact is that they are not really RESTful because they are not always
making direct use of the available verbs to perform the tasks - however we
get away with it because the definition of REST is a bit loose.  The
problem arises when third party consumers of your simple XML web services
want your published WSDL or XML schema or whatever.  People these days
expect to be supplied with a WSDL so that they can use it to generate their
proxy classes, effectively writing the web service client for them (or the
bulk of it).  Give them documentation instead of a WSDL and they don't know
where to start.

You don't need to know a lot about WSDL's until you start developing
more complex data streams that talk to many different platforms and
languages.  In the end, if you are offering public web services, you
will inevitably become familiarized with WSDL/XSD/XML because not
everyone does it like Microsoft.  And then once you become familiar
with WSDL/XSD/XML and have to "debug" it for your customers, you will
inevitably say to yourself: why not simplify this approach to use HTTP
POST + simple XML (like I said earlier in this post).

Just my experience of the roughly 10yrs I have been doing web services
(with the last 6 years doing it almost fulltime).
