Question

I trying to make a web service accessible to Matlab. I can call it from PHP but Matlab doesn’t seem to be able to parse the definition.

??? Attempt to reference field of non-structure array.

Error in ==> createClassFromWsdl>parseWsdl at 72
se = defTypes.getExtensibilityElements().get(0);

Error in ==> createClassFromWsdl at 32
[R, schema] = parseWsdl(wsdlUrl);

WSDL File:

<?xml version ='1.0' encoding ='UTF-8' ?>
<definitions name='server3'
  targetNamespace='http://server.edu/php/soap_test/server3.wsdl'
  xmlns:tns='http://server.edu/php/soap_test/server3.wsdl'

  </operation>
</binding>

<service name='getRangeService'>
  <port name='getRangePort' binding='getRangeBinding'>
    <soap:address location='http://server.edu/php/soap_test/soap_server3.php'/>
  </port>
</service>

</definitions>

Reading the Matlab docs states:

The createClassFromWsdl function works with WSDL documents that comply with the WS-I 1.0 standard and use one of these forms: RPC-encoded, RPC-literal, Document-literal, or Document-literal-wrapped.

My Matlab install works with some sample WSDL files. So now Im trying to figure out what’s wrong with mine. Suggestions?

Answer 1

FWIW: There are four issues:

1) the ‘xsd:complexType’ entries need to be in a ‘types’ section.

2) the ‘service/port#binding’ attribute needs to be ‘tns:getRangeBinding’.

3) ‘binding/operation/soap:operation#soapAction’ should be ‘urn:xmethods-get-range:getRange’

4) ‘binding/operation/input/soap:body#namespace’ should match #3.
