For any one out there trying to import wsdl files from the SAP PI ESB (Enterprise Service Bus) be aware of a problem that we have encountered.The WSDL generated by PI has a https tag which looks something like this :
<wsdl:port name=“HTTPS_Port” binding=“p1:Vendor_Out_SyncBinding”>
<soap:address xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" location="https://*****:443/XISOAPAdapter/MessageServlet?senderParty=&senderService=LOTUS_NOTES&receiverParty=&receiverService=&interface=Vendor_Out_Sync&interfaceNamespace=urn:za.co.******:frontend:fi" />
</wsdl:port>
Delete this from the WSDL and it will import and compile correctly. If you dont it can start compiling and then just throws an error found on the status bar.
