NULL Values

[Alexander Mischur]

Hello everybody,
I had problems with NULL values of parameters.
My Client sent always this:
<sample>
   <number>987654321</number>
   <callnumber>12345678</callnumber>
   <callid xsi:nil="true"/>
</sample>
but the webservice i called, wants this if the callid is null:
<sample>
   <number>987654321</number>
   <callnumber>12345678</callnumber>
</sample>
So, the tag callid musst not be sent.
I've generated the stub with wsdl2java from the wsdl.
I'll set this code in the method:
      _call.setProperty(org.apache.axis.client.Call.SEND_TYPE_ATTR, 
Boolean.FALSE);
      _call.setProperty(org.apache.axis.AxisEngine.PROP_SEND_XSI, 
Boolean.FALSE);


So, please  help me, because i don't know the attribute
which i had to set or which combination of attributes.
Thx
alex
