Re: wsdl file: microsoft only?

[Nicholas Quaine <qu...@jpmorgan.com>]

Apache server side does not require or use a wsdl file
You only need a wsdl file if you want to use the high level API of the MS Soap
Toolkit on the client side
The wsdl file will then serve as a method descriptor so that the soap toolkit
can encode your requests
If you use the low level API then you can call services on apache or any other
soap service without any wsdl file
Note though that the wsdl / high-level API may actually work better for you in
the case where you want simplicity on the client side

There are examples in the microsoft toolkit help on the low level API
A typical client looks something like the below
There are some traps to interoperability - see the archives for these as I have
already posted them many times

Subject:  wsdl file:  microsoft only?




I was able to get my Apache soap server running fine and then went to get a
Microsoft soap client to talk to it.  But it looks like Microsoft requires
this "wsdl" file on the server.  Is this the case even if I am running
Apache on the server?  None of the Apache examples seem to require this file
(or the wsml file).  If I want a Microsoft soap client to talk to an Apache
soap server, do I *have* to have these files, or is there a way around it?
If someone has a vb example of a Microsoft client talking to an Apache
server (without using wsdl files), please send it to me.

Conversely, if I have a Microsoft soap server, and a Java (Apache) client,
how does that work?  How would my Apache client specify what wsdl file to
use?

Thanks,
Ed
