SOAP4R WSDL response

1

I’m trying to use wsdlDriver.rb to call a Web service. I have a WSDL
file. When I run my script, it connects to the Web service, calls the
operation I specify (“approve”), and receives the response string.
However, it doesn’t put the response string into the message part that
the operation “approve” uses as its output message. Instead, it tries
to find something called “approveResponse”, which is not described in
the WSDL file. I see the following error:

c:/ruby/lib/ruby/1.8/wsdl/soap/complexType.rb:69:in
child_defined_complextype': Cannot find {http://www.w3.org/2001/XMLSchema}string as a children of {http://loans.org/wsdl/loan-approval}approveResponse. (RuntimeError) from c:/ruby/lib/ruby/1.8/soap/encodingstyle/soapHandler.rb:382:indecode_tag_by_wsdl’
…

Why isn’t the response string being put into the message part that the
operation “approve” uses as its output message?

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

I’m trying to use wsdlDriver.rb to call a Web service. I have a WSDL
file. When I run my script, it connects to the Web service, calls the
operation I specify (“approve”), and receives the response string.
However, it doesn’t put the response string into the message part that
the operation “approve” uses as its output message. Instead, it tries
to find something called “approveResponse”, which is not described in
the WSDL file. I see the following error:

c:/ruby/lib/ruby/1.8/wsdl/soap/complexType.rb:69:in
child_defined_complextype': Cannot find {http://www.w3.org/2001/XMLSchema}string as a children of {http://loans.org/wsdl/loan-approval}approveResponse. (RuntimeError) from c:/ruby/lib/ruby/1.8/soap/encodingstyle/soapHandler.rb:382:in decode_tag_by_wsdl’
…

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:stringapproved</xsd:string>
</ns1:approveResponse>

Now, the WSDL for the reply message used to be

so I tried changing that to

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

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.
