Encoding style of standard serializers

[landgraf]

Hi,

i'm calling two .NET webservices via Axis as client toolkit. I generated 
the client stubs
via the wsdl2java Ant-Task. The request to the first webservices works 
fine, it looks like that:

<soapenv:Envelope [...cut...]>
 <soapenv:Body>
  <Save xmlns="http://diamant-software/webservices/";>
   <session>FHLHP</session>
   <data>
    <TransactionType>AR</TransactionType>
    <TransDate>2002-05-19T22:00:00.000Z</TransDate>
   </data>
   <flags xsi:type="xsd:int">0</flags>
   <fields_to_save xsi:nil="true"/>
  </Save>
 </soapenv:Body>
</soapenv:Envelope>

the second request looks like that:

<?xml version="1.0" encoding="UTF-8"?>
   <soapenv:Envelope [.cut..]> 
      <soapenv:Body> 
         <Save xmlns="http://diamant-software/webservices/";> 
            <session>FFLFAVDXHJ</session> 
            <data> 
               <declRegDescription xsi:nil="true" xmlns=""/> 
               <commonGenLedgAcc xmlns="">024000</commonGenLedgAcc> 
               <IBANNumber xsi:nil="true" xmlns=""/> 
               <declRegCountry xsi:nil="true" xmlns=""/>
          </data>
        </Save> 
      </soapenv:Body>
   </soapenv:Envelope>

why does Axis put those those xsi:nil="true" and xmlns="" statements in 
the second request?
Did i do something wrong when generating the Axis client stubs?

any help is greatly appreciated,
Thomas
