SOAP Server - having problems

[philaj]

I'm trying to create a SOAP Server that will process requests from another system.

 

The system sends a SOAP Envelope of XML in and I need to extract the fields and do some processing.

 

Don't fully understand the WSDL they have provided - but I have created the following basic server code (See below) - which appears to run - and some debugging shows that it is called.

 

At debug point 0 - outputs a text file containing 'here' - and at point 1 outputs text file containing the XML as below.

BUT - My function never seems to be called - is there something basic I'm missing?

Please any help much appreciated.

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><DynamicChange><VTID>5572</VTID><ExtID>5572</ExtID><FunctionCode>5</FunctionCode><Status>3</Status><FMExtID>WIECR</FMExtID><Termin_von>2018-02-21T00:00:00+00:00</Termin_von><Termin_bis>2018-02-23T00:00:00+00:00</Termin_bis><Plandauer>480</Plandauer><Besuchsdauer>480</Besuchsdauer><Planankunft>2018-02-27T09:00:00+00:00</Planankunft><Infotext></Infotext></DynamicChange></soap:Body></soap:Envelope>
