Can anyone create a matlab-class from this wsdl?

Hi,

I try to build a matlab-class from this wsdl: https://demo.neplan.ch/NEPLAN360_Demo/Services/External/NeplanService.svc. It works for c# but in matlab i'm getting "java.lang.NullPointerException".

I'm using 2018a on win10 and i've set the WSDLToopPath to jdk-7u75-windows-x64 & apache-cxf-2.7.18. I also tried cxf 2.7.10 and 3.2.4. From the service i've tried both normal and singlefile wsdl.

Can anyone help me to build a class out of this wsld?

Thank you in advanced, T.
