Web service callout failed: Unable to parse callout response for w3 xml schema

I'm new to Apex development and ran into the following issue I can't decipher when making a simple web service call from the Force IDE.

 

I generated the Apex class from the WSDL for my client's service and used that to make the web service call. The call succeeds in getting a response from the web service; I can see the expected data in the Execute Anonymous results window. But it eventually throws the following exception:

 

09:06:22.193|FATAL_ERROR|System.CalloutException: Web service callout failed: Unable to parse callout response. Apex type not found for element http://www.w3.org/2001/XMLSchema=schema

 

Any help would be greatly appreciated.

      <s:element name="getSearchResultsResponse">
        <s:complexType>
          <s:sequence>
            <s:element minOccurs="0" maxOccurs="1" name="getSearchResultsResult">
              <s:complexType>
                <s:sequence>
                  <s:any minOccurs="0" maxOccurs="unbounded" namespace="http://www.w3.org/2001/XMLSchema" processContents="lax" />
                  <s:any minOccurs="1" namespace="urn:schemas-microsoft-com:xml-diffgram-v1" processContents="lax" />
                </s:sequence>
              </s:complexType>
            </s:element>
          </s:sequence>
        </s:complexType>
      </s:element>

 Here's the snippet for your result element from the WSDL.  Notice the <s:any> elements.  We don't support that schema type.  For a full list of what we support, see http://wiki.developerforce.com/index.php/Apex_Web_Services_and_Callouts#WSDL2Apex (look for the section called "Supported WSDL Features").

Is that the whole error message you're receiving?

Here is what I believe is the relevant output from the Execute Anonymous results window:

12:00:28.240|EXCEPTION_THROWN|[118]|System.CalloutException: Web service callout failed: Unable to parse callout response. Apex type not found for element http://www.w3.org/2001/XMLSchema=schema
dkadordkador

You'd have to post your WSDL for me to be sure, but the fact that there's an <xs:schema> element in your SOAP response is pretty strange.  My best guess is your WSDL uses at least one unsupported feature for WSDL2Apex.  Unfortunately the current implementation does not always error out when generating Apex from an invalid WSDL.
opiedogopiedog

I don't see a way to attach a document so I'll paste it.

NOTE: My client's web service isn't adequately secure so I got rid of any references to the client's site.

Also: One error I did get from WSDL2Apex was about multiple bindings. In my first attempt I stripped out the MyWSWebServiceSoap12 binding since I read somewhere that it's not supported.

Thanks for your help!!!

 

Here's the WSDL (including both bindings, but with some elements removed to get under the 20,000 character message limit):

You should be able to attach a file.  I'll need the full WSDL to do any real debugging.  You can edit out the client info, of course.  Please attach the exact WSDL you used in the WSDL2Apex process.
opiedogopiedog

At the risk of exposing my lack of a clue, I gotta admit that I don't see any way to attach files. What's the secret?
dkadordkador

That's weird.  You don't see the "Attachments" section right under the box where you type your reply?

 

If not, e-mail it to me at dkador AT salesforce DOT com.
opiedogopiedog

Nope - no attachments section. I'll email right now.
opiedogopiedog

Please confirm whether or not you received the email with the WSDL attached. Thanks!

I'll dig into this and see if it resolves the issue. Thank you so much for your help!
