Urgent interop problem with .NET if String parameter is null

[Thomas Börkel]

HI!

Consider the following method in a Java server:

  public String parameterTest(short s, int i, double d, String t, boolean b)


Now, if .NET is the client and I call parameterTest(1, 2, 3.5, null, true), then .NET 
does not pass in 't' at all. This results in an error in Axis.

This is the SOAP message from .NET for this:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"; 
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"; 
xmlns:tns="http://p2test.p2plus.apag.com"; 
xmlns:types="http://p2test.p2plus.apag.com/encodedTypes"; 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
  <soap:Body soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";>
    <tns:parameterTest>
      <s xsi:type="xsd:short">1</s>
      <i xsi:type="xsd:int">2</i>
      <d xsi:type="xsd:double">3.5</d>
      <b xsi:type="xsd:boolean">true</b>
    </tns:parameterTest>
  </soap:Body>
</soap:Envelope>


I am using Axis Beta1 and .NET 1.0. Anyone any ideas how to get this to work? Is it 
.NET's fault? Then I'll file a bug report to MS about this.

Thanks!

Thomas
