Problem with .NET client that remove null parameters

[Giannandrea Castaldi <g....@gmail.com>]

Hi,
I've an axis server (axis 1.1 on tomcat 4.1.30) where one argument of
a method may be null and if I call the web service from an axis client
passing the null argument the call succeedes.
But in production the web service is called by a .NET client
(Microsoft WSE 2.0 SP3) that remove any null parameter and then the
axis call validation fails because the signature of the method is
wrong.
I've read this post http://java2.5341.com/msg/99543.html where they
suggest to add the parameter names in the wsdd file but our
server-config.wsdd already contains them:

---- cut here ----
...
  <operation name="myMethod" qname="ns1:myMethod"
returnQName="myMethodReturn" returnType="xsd:int"
xmlns:ns1="http://MyService"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <parameter name="param1" type="xsd:string"/>
   <parameter name="param2" type="xsd:string"/>
   <parameter name="param3" type="xsd:string"/>
   <parameter name="param4" type="xsd:string"/>
   <parameter name="param5" type="xsd:string"/>
   <parameter name="param6" type="xsd:base64Binary"/>
   <parameter name="param7" type="xsd:int"/>
   <parameter name="param8" type="xsd:boolean"/>
   <parameter mode="out" name="param9" type="xsd:string"/>
  </operation>
...

Is there a way in axis 1.1 (or 1.2RC3) to accept call with missing arguments?


Here is the error message sent back:
