Consuming a JAX-WS in a Mule ESB flow

I want to consume a JAX-WS service method. the methode is named find and accept a String as argument.

this the Mule flow :

<flow name="InvokeAWebServiceFlow1" doc:name="InvokeAWebServiceFlow1">
    <file:inbound-endpoint path="C:\MuleStudio\SandBox\input" pollingFrequency="3000" responseTimeout="10000" doc:name="File"/>
    <file:file-to-string-transformer encoding="UTF-8" mimeType="text/xml" doc:name="File to String"/>
    <cxf:jaxws-client port="douaneWSPort"   serviceClass="WSDL.DouaneWS" doc:name="SOAP" enableMuleSoapHeaders="true" operation="find"/>
    <echo-component doc:name="Echo"/>
    <file:outbound-endpoint path="C:\MuleStudio\SandBox\output" outputPattern="#[function:datestamp:dd-MM-yy]_#[function:systime].xml" responseTimeout="10000" doc:name="File"/>
</flow>

I put a argument into a file, in this exampl the argument is "ctr1" after i put the file into the inbound endpoint, after that the file is transformed into a String and goes to the JAX-WS client, finally the respponse is written into an output file.

when I run the flow I get as an output :

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
 <ns2:find xmlns:ns2="http://douane.ws/">
  <id>ctr1</id>
 </ns2:find>
</soap:Body>
</soap:Envelope>

the output is the SOAP the request instead of the expected SOAP Response, that should be somthing like:

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
   <S:Body>
      <ns2:findResponse xmlns:ns2="http://douane.ws/">
         <return>
            <quality>medium</quality>
            <price>150</price>
            <idProd>ctr1</idProd>
         </return>
      </ns2:findResponse>
   </S:Body>
</S:Envelope

> .

The error generate is

Any help ??

If the webservice you want to consume is hosted, let's say at http://domain.com/ws , than your configuration should look like this:

<flow name="InvokeAWebServiceFlow1" doc:name="InvokeAWebServiceFlow1">
<file:inbound-endpoint path="C:\MuleStudio\SandBox\input" pollingFrequency="3000" responseTimeout="10000" doc:name="File"/>
<file:file-to-string-transformer encoding="UTF-8" mimeType="text/xml" doc:name="File to String"/>
<cxf:jaxws-client port="douaneWSPort"   serviceClass="WSDL.DouaneWS" doc:name="SOAP" enableMuleSoapHeaders="true" operation="find"/>
<http:outbound-endpoint address="http://domain.com/ws" />
<echo-component doc:name="Echo"/>
<file:outbound-endpoint path="C:\MuleStudio\SandBox\output" outputPattern="#[function:datestamp:dd-MM-yy]_#[function:systime].xml" responseTimeout="10000" doc:name="File"/>
</flow>
