Holder parameters

Hi,

I have a problem with holders.
I use 12/12/2001 axis version.

My jws file is this one :
"
import javax.xml.rpc.holders.*;

public class Essai {
 
  public void tryHolder(StringHolder theString)
  {
	  theString._value = "hello world";
  }
}
"

The ?wsdl generated is the following :
"
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions targetNamespace="http://localhost:8080/axis/Essai.jws"
xmlns="http://schemas.xmlsoap.org/wsdl/"

xmlns:intf="http://localhost:8080/axis/Essai.jws"

  </wsdl:message>

  </wsdl:message>
  <wsdl:portType name="Essai">
    <wsdl:operation name="tryHolder">

      <wsdl:output message="intf:tryHolderResponse"/>
    </wsdl:operation>
  </wsdl:portType>
  <wsdl:binding name="Essai.jwsSoapBinding" type="intf:Essai">

      <wsdl:output>

  </wsdl:binding>

    <wsdl:port binding="intf:Essai.jwsSoapBinding" name="Essai.jws">

    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>
"
This seems to be correct.

I used C# to call tryHolder
"
EssaijwsService client = new EssaijwsService();
string myString = "nothing";
client.tryHolder(ref myString);
Console.WriteLine(myString);
"

But an exception occurs.
"
An unhandled exception of type 'System.Web.Services.Protocols.SoapException'
occurred in system.web.services.dll

Additional information: java.lang.IllegalArgumentException: argument type
mismatchOn object "Essai" method name "tryHolder" tried argument types:
java.lang.String
"


I used TCPMon to see why :

"
POST /axis/Essai.jws HTTP/1.1 
[...]
<?xml version="1.0" encoding="utf-8"?> 
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Body

     <q1:tryHolder xmlns:q1="http://localhost:8080/axis/Essai.jws">
       <inOut0 xsi:type="xsd:string">nothing</inOut0>
     </q1:tryHolder>
   </soap:Body>
</soap:Envelope>
"
This seems correct too.

But I get :
