To get it to work, you need to
1. change $configuration['soapEngine'] = "nusoap"; to "phpsoap"
2. then in services/pog.wsdl, scroll to the bottom, and modify this
line
<soap:address location="http://www.phpobjectgenerator.com/services/
soap_php5.php"/>
so that it points to your local copy of soap_php5.php
hope this helps,
