Consuming a JAX-WS in a Mule ESB flow - soap

Question

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
>
.

Any help ??

Answer 1

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>
