[RESOLVED] Fatal Error: WSService::reply() - raw post data not found

Hello, please help me debug a web service server error.  I only get the error when accessing the service via SOAP.  When accessing via HTTP GET the service responds correctly.  You can see the HTTP communication below in blue.  The PHP server code is in green.  I am trying to access a test server from MS InfoPath and soapUI.  In both cases I get the Fatal Error.  But when accessing the URL directly with HTTP GET, it is okay.
