Invoke SOAP Web Service using Camel

Hi Camel Experts,

I need to invoke a SOAP based web service using Camel. Or in other words my requirements that my application would push data on JMS queue. This data would further be handed over to a third party that has exposed a web service this purpose. The web service would also send back a reply.

For sake of simplicity I am using the Web Service available at:  http://www.webservicex.net/length.asmx

 REQUEST:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:web="http://www.webserviceX.NET/">
   <soapenv:Header/>
   <soapenv:Body>
      <web:ChangeLengthUnit>
         <web:LengthValue>100</web:LengthValue>
         <web:fromLengthUnit>Inches</web:fromLengthUnit>
         <web:toLengthUnit>Feet</web:toLengthUnit>
      </web:ChangeLengthUnit>
   </soapenv:Body>
</soapenv:Envelope>

RESPONSE:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Body>
      <ChangeLengthUnitResponse xmlns="http://www.webserviceX.NET/">
         <ChangeLengthUnitResult>8.3333333333333339</ChangeLengthUnitResult>
      </ChangeLengthUnitResponse>
   </soap:Body>
</soap:Envelope>

From documentation, it seems that I can use CXF component for this purpose. However, I am not able to get clarity about the same. I am trying to build the route on the following lines:

from("cxf:http://www.webservicex.net/length.asmx?wsdlURL=http://www.webservicex.net/length.asmx?WSDL&dataFormat=MESSAGE")
    .to("log:SOAPWSConsume?showAll=true&multiline=true&level=ERROR");

I have tried other options like serviceName, portName but have not been successful in invoking the same. An example of a error:

java.lang.AbstractMethodError: org.apache.crimson.tree.XmlDocument.setDocumentURI(Ljava/lang/String;)V
    at org.apache.cxf.staxutils.StaxUtils.read(StaxUtils.java:1125)
    at org.apache.cxf.wsdl11.WSDLManagerImpl.loadDefinition(WSDLManagerImpl.java:248)

So, my confusions (and hence queries) are:

# Do i need to generate client side stubs using the utilities like wsdl2java
# How can i provide the input parameters (like length, convert from, convert to)
# If I need to provide authentication information, how can i provide the username password.

A pointer to a working example would be of great help.
