webservice could not generate stub object

[CF_Geliebter]

Hi,
I am trying to make a simple web service. the .cfc file works as .cfc?wsdl
browsing. when I invoke it as component name, it's work fine too. but when I
try to invoke it as webservice then it shows error "Could not generate stub
object for web service invocation." Here I am giving a sample example.
1. [url]http://localhost/_com/testws.cfc?wsdl[/url]
<cfcomponent output="yes" >
<cffunction name="getServiceValue" returntype="string" access="remote" >
<cfreturn "this is the first web service output.">
</cffunction>
</cfcomponent>
2. [url]http://localhost/_test/testinvoke.cfm[/url]
<cfinvoke webservice=" [url]http://localhost/_com/Dataview.cfc?WSDL[/url] "
method="getServiceValue" returnvariable="returnedText"/>
<!--- <cfinvoke component="_com.testws" method="getServiceValue"
returnvariable="returnedText"/> ---->
<cfoutput> #variables.returnedText# </cfoutput>

Error :

Could not generate stub objects for web service invocation.
Name: [url]http://localhost/_com/Dataview.cfc?WSDL[/url] . WSDL:
[url]http://localhost/_com/Dataview.cfc?WSDL[/url] . org.xml.sax.SAXException: Fatal
Error: URI=null Line=1: Content is not allowed in prolog. It is recommended
that you use a web browser to retrieve and examine the requested WSDL document
for correctness. If the requested WSDL document can't be retrieved or it is
dynamically generated, it is likely that the target web service has programming
errors.

Do you have any idea to resolve it?

Thanking in advance.

Could any of you help me on above problem?
thx...

There is something wrong with the WSDL that is being retrieved by cfinvoke.

The key is the error: "Content is not allowed in prolog." There is
something in the WSDL XML that isn't XML. Check 'view source' in a browser.

Perhaps you are using a DevNet edition that puts a watermark in the output?

I have no problems with that WSDL.
