Webservice API call

Question

I have been trying to make Webservice call to "https://webservice.exacttarget.com/etframework.wsdl" using coldfusion server 9.0 without much success. My code recognizes WSDL and it methods but When I call method it throws following error:
Web service operation Describe with parameters {{DESCRIBEREQUESTS={[Lcom.et.client.ObjectDefinitionRequest;@78b0e1}}} cannot be found.
Please suggest.....
MyCode CFM file code:

We do a lot of work with web service APIs using coldfusion.  A while ago, we decided it was much easier (especially when dealing with complex web service invocations) to switch to posting/receiving the raw XML SOAP messages in order to exchange data with the remote web service.  Ben Nadel has a great article that outlines what is involved:
http://www.bennadel.com/blog/1809-Making-SOAP-Web-Service-Requests-With-ColdFusion-And-CFH TTP.htm
What's more, you can use a lot of free/OSS tools to generate a template for the Request/Response SOAP messages, so it really just winds up being a matter of creating your XML in a cfsavecontent block and adding your variables in place of the sample text.  We use SOAPSonar from Crosscheck networks (http://www.crosschecknet.com/products/soapsonar.php) - they have a free "personal" edition that will parse a WSDL and generate the resulting XML SOAP messages that you can use as a template.
The only major issue is you have to watch out for the XML namespaces in the response that comes back from the web service.  ColdFusion (not surprisingly) has a major issue with extracting data using XMLSearch() from an XML node that includes a name space.  There are a couple of work-arounds - you could use a local-name() xpath method to perform a namespace-agnostic search, or you could use regular expressions to just strip all the namespace data out of the XML and parse using ColdFusion.
Anyway, the implementation winds up looking something like this:
<!--- build Soap XML --->
<cfsavecontent variable="sSOAPBody">
<cfoutput>
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
     <myMethod>
          <firstArgument>#MyValue#</firstArgument>
     </myMethod>
</soap:Body>
</soap:Envelope>
</cfoutput>
</cfsavecontent>
<!--- Send SOAP data using CFHTTP --->
<cfhttp url="URL of Web service (e.g. .asmx, .cfc - no WSDL)" method="post">
<cfhttpparam type="header" name="SOAPAction" value="http://target_namespace_goes_here/method">
<cfhttpparam type="header" name="accept-encoding" value="no-compression">
<cfhttpparam type="xml" value="#trim(sSOAPBody)#">
</cfhttp>
<!--- Parse XML Response in CFHTTP.FileContent --->
