How to send the response back to the caller when exposing cxf webservice using camel

Hi All,

I am trying to expose a sample CXF SOAP based webservice using camel
cxfbean component. I am using JBoss Fuse for deploying camel route as
bundle. I am folllowing the bottom up approach. I created the WSDL file
first then I use the CXF code gen maven plugin to generate the java class
using the goal wsdl2java.

I have given the pastebin link for all the files

wsdl file : http://pastebin.com/v0aKgNTy

Camel Context : http://pastebin.com/SXYzNd0S

Processor Class : http://pastebin.com/T2e4vHir

SOAP Request and Response : http://pastebin.com/BiH9Au6P

I am trying to set the response back to the caller (SOAP UI in this case)
who invokes my webservice which is being exposed by camel from endpoint.

I am using <transform> in the camel route to send the response back to the
caller as

<transform>
<simple></simple>
</transform>

But the behavior of the above mentioned is not stable. Sometimes I get the
response properly as expected in the SOAP UI as follows

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ns2:calculatorResponse
xmlns:ns2="http://www.example.org/calculatorWS/">
<response>Response from calculate operation is ::: 2 * 3 =
6</response>
</ns2:calculatorResponse>
</soap:Body>
</soap:Envelope>

And most of the time I am getting response with no content in the soap body.

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body/>
</soap:Envelope>

Also, when I checked the fuse.log I could see the renspone as

I am bit confused here, why the response is not getting generated properly.
Am I missing something ?

Any suggestion or help will be really helpfull. I have attached the project
as an attachment. Camel-CXF-Calculator.rar
