Re: Microsoft .NET frontending IBM i

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).

I find it baffling that someone developing web services cannot interpret or
read a WSDL or XML schema. It's not uncommon. I run into it all the time.

Isn't that the point of object oriented development. Building black
boxes :-)

Just a minute. Let me get my hammer and chisel. Clang...Clang...
Ouch :-)

Try bending your mind around it and you might find that the better way it
to NOT hand code WSDL..... Clang...Clang...

Then I'd say you are working with a black box, letting the WSDL be
generated for you. That may work great, until you need to interpret or
read the WSDL or schemas while debugging or troubleshooting.
