How to call a third party webservice using Apache camel using cxf componnet

问题


I went through the example on Apache camel website and camel in action and both focus heavily on exposing a webservice. The only example I found online does not work.

I am trying to access a third party webservice wsdl - http://www.webservicex.net/CurrencyConvertor.asmx?WSDL

This service has a operation/method that calculates the currency rate. The operation name is "ConversionRate".

I defined the route like this -

      <?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>

I have defined the sample payload xml as - 

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

I am getting this error when I run this example.

回答1:


The destination URI appears to be incorrect according to the CXF documentation.

The format for serviceName and portName should be {namespace}name

Try with:

  • serviceName={http://www.webserviceX.NET/}CurrencyConvertor
  • portName={http://www.webserviceX.NET/}CurrencyConvertorSoap
