如何通過使用cxf componnet使用Apache駱駝來調用第三方webservice

我在Apache駱駝網站和駱駝行動中經歷了這個例子，並且都非常重視暴露web服務。我在網上找到的唯一例子不起作用。如何通過使用cxf componnet使用Apache駱駝來調用第三方webservice

我試圖訪問第三方Web服務的WSDL - http://www.webservicex.net/CurrencyConvertor.asmx?WSDL

該服務有一個操作/方法計算匯率。操作名稱是「ConversionRate」。

我這樣定義的路線 -

 <?xml version="1.0" encoding="UTF-8"?> 
<!-- Configures the Camel Context--> 

<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xmlns:camel="http://camel.apache.org/schema/spring" 
     xmlns:cxf="http://camel.apache.org/schema/cxf" 
     xsi:schemaLocation=" 
     http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 
     http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd"> 


    <camelContext xmlns="http://camel.apache.org/schema/spring"> 

    <route> 
     <description>here is a sample which processes the input files 
     (leaving them in place - see the 'noop' flag) 
     then performs content based routing on the message using XPath</description> 
     <from uri="file:src/data/order?noop=true"/> 
     <log message="${body}"/> 

     <to uri="cxf://http://www.webservicex.net/CurrencyConvertor.asmx?wsdlURL=http://www.webservicex.net/CurrencyConvertor.asmx?wsdl&amp;serviceName=CurrencyConvertor&amp;portName=http://www.webserviceX.NET/tns:CurrencyConvertorSoap&amp;dataFormat=MESSAGE"/> 
     <log message="${body}"/> 
    </route> 
</camelContext> 

</beans>

我已經定義了樣品的有效載荷XML作爲 -

<order> 
     <Id>1</Id> 
     <Price>10.00</Price> 
     <Quantity>2</Quantity> 
</order>

當我運行這個例子中我得到這個錯誤。

根據CXF文檔，目標URI顯示爲不正確。

爲serviceName和portName格式應該是{namespace}name

與嘗試：
