Subject: Re: SOAP4R WSDL response

Hate to reply to my own question, but I've learned something about what 
was going wrong. Instead, I have a new question.

On May 29, 2004, at 5:55 PM, I wrote:

It turns out that the WSDL didn't match the reply from the server. The 
reply body is

<ns1:approveResponse soapenv:encodingStyle="..." xmlns:ns1="...">
   <xsd:string>approved</xsd:string>
</ns1:approveResponse>

Now, the WSDL for the reply message used to be

<message name="approvalMessage">
   <part name="accept" type="xsd:string"/>
</message>

so I tried changing that to

<message name="approvalMessage">
   <part name="approveResponse" type="xsd:string"/>
</message>

but that didn't work. I saw the same error message ("can't find string 
as child of approveResponse"). So I tried


<message name="approvalMessage">
   <part name="string" type="xsd:string"/>
</message>

and it worked! Now I need to figure out why I have to call the part 
"string". Does anyone know what is going on here?

Thanks for your help.

Jim
