Problem connecting to web service.

[Andrea V.F.]

I've implemented a Test web service for using in infopath.

The web service is an ActiveX Dll created with Visual Basic 6.

I've generated the WSDL with the "WSDL Generator" Included into the
"Microsoft SOAP Toolkit 3" and then changed the style from RPC to
document and use from encondig to literal.

While loading the WSDL in infopath I can see the list of services
(only one in this test) but I receive the followind error while
continuing the "Data Connection Wizard":

"The schema information for the specified Web service is either
missing or not valid"

This is the WSDL file:

<?xml version='1.0' encoding='UTF-8' ?>
