[bohr.qiu]

I create a webservice with axis2 like that：

 

public void setWeather(@WebParam(name = "weather") Weather weather,

                            @WebParam(name = "city") String city,

                            @WebParam(name = "country") String country) {

                   System.out.println("weather:" + weather);

                   System.out.println("city:" + city);

                   System.out.println("country:" + country);

                   this.weather = weather;

         }

 

Then I send a soap message :

 

<?xml version='1.0' encoding='UTF-8'?>

<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope";>

         <soapenv:Body>

                   <ns2:setWeather xmlns:ns2="http://service.pojo.sample";>

                            <ns2:weather>

                                     <ns1:forecast
xmlns:ns1="http://data.pojo.sample/xsd";>rain</ns1:forecast>

                                     <ns1:howMuchRain
xmlns:ns1="http://data.pojo.sample/xsd";>102.3</ns1:howMuchRain>

                                     <ns1:rain
xmlns:ns1="http://data.pojo.sample/xsd";>true</ns1:rain>

                                     <ns1:temperature
xmlns:ns1="http://data.pojo.sample/xsd";>20.3</ns1:temperature>

                            </ns2:weather>

                            <ns2:country>china</ns2:country>

                   </ns2:setWeather>

         </soapenv:Body>

</soapenv:Envelope>

And I receive 

weather:Weather [temperature=20.3, forecast=rain, rain=true,
howMuchRain=102.3]

city:china

country:null
