Please urgent! .Net client can't invoke Axis webservice

I have a Web Service in Axis (latest version) which
can't be called by a .Net client (VB-based). I believe
the problem is with the way href's are built in .Net.
Axis uses multiRef, but .Net doesn't.

Another problem I've noticed: the WSDL file that gets
generated from the service url with the ?WSDL is
incorrect. It states that a StringHolder type is
returned (from http://holders.rpc.xml.javax
namespace), but what gets returned is a xs:string
type.

As a consequence, I had to supply the .Net client with
the wsdl file I've manually created (and which was
used to feed the Axis wsdl2java tool). 

Included below are the wsdl file, a sample good
request/response from the JUnit test class and the bad
request/response from .Net.

Many thanks,


Nuno Guerreiro
