I found the error on your soap request. But I can't show you the solution in Xpert-Ivy.
Your error is due to a missing START_ELEMENT means: the SOAP-request is missing the name of your webservice.
What you send:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:bet="https://venus.zhaw.ch:8443/ibis/ws/1383213506125/Betreibungsregisterauszug_ws_Listener">
<soapenv:Header/>
<soapenv:Body>
<bet:BetreibungsregisterauszugErhalten>CH450234</bet:BetreibungsregisterauszugErhalten>
</soapenv:Body>
and what it should be:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:bet="https://venus.zhaw.ch:8443/ibis/ws/1383213506125/Betreibungsregisterauszug_ws_Listener">
<soapenv:Header/>
<soapenv:Body>
<unk:betreibungsregisterauszugerhalten>
<bet:BetreibungsregisterauszugErhalten>CH450234</bet:BetreibungsregisterauszugErhalten>
</unk:betreibungsregisterauszugerhalten>
</soapenv:Body>
The difference is the unk:betreibungsregisterauszugerhalten-tag in the SOAP-request. The tag specifies the name of the webservice which should handle your request. It is nescessary to know the name of the webservice, because there can be several webservices where your request may fit.
Where the first part: unk stays for the package name. unk= unknown in this case.
The second part: betreibungsregisterauszugerhalten is the method name, defined in your top-level-interface. Like betreibungsregisterauszugerhalten().
If this doesn't help you, please provide a full code example.
