2-d Arrays as method argument and return type

[Prasad Badkas]

Hi

I am trying to invoke a method which accepts 2-d arrays as input parameters
and return type is also a 2-d array. I am using MS SOAP toolkit on server
side and Apache SOAP on client side. I was successful to invoke methods
accepting and returning 1 - dimensional arrays by using the default
serializer (ArraySerializer) provided in the API. I tried to extend same
logic to cover multi-dimensional arrays. I modified the .wsdl file to define
the 2-d array as follows to indicate that ArrayOfString2d is composed of 2
data types of ArrayOfString type. The complex type for "ArrayOfString" is
auto generated by the WSDL generator of MS SOAP Toolkit.

****
      <complexType  name ='ArrayOfstring'>
        <complexContent>
          <restriction base='SOAP-ENC:Array'>
            <attribute ref='SOAP-ENC:arrayType' wsdl:arrayType='string[]'/>
          </restriction>
        </complexContent>
      </complexType>

      <complexType  name ="ArrayOfstring2d">
        <sequence>
            <element name = 'arr0' type = 'ArrayOfstring'/>
            <element name = 'arr1' type = 'ArrayOfstring'/>
        </sequence>
      </complexType>
****

The request gets generated successfully but I get following error :

  Fault Code   = SOAP-ENV:Server
  Fault String = WSDLOperation: The SoapMapper name had a type which could
not be converted during IDispatch::Invoke


Any workaround for above ?

Thanks,
