XMLport – a web services integration example for WDTU

WDTU subscribes to a service that compiles listenership data. That data is provided to subscribers in the form of XML files. The agency that provides the service has agreed to push that XML data directly to a web service exposed by our NAV 2015 system. This approach will allow WDTU to have access to the latest listenership data as soon as it is released by the agency.

WDTU must provide access to the XMLport that fits the incoming XML file format. The handshaking response expected by the agency computer from our web service is a fixed XML file with one element (Station ID) and an attribute of the said element (Frequency).
