UWL Ad Hoc - HELP Detlev !!!!!!!!

We are trying to create a portal component that pulls tasks(items) from the existing Ad Hoc workflow system using the API available on the portal but we have not been able to find any detailed documentation, code samples or tutorials anywhere. We have successfully written code that instantiates UWLContext and UWLService objects and begins a UWL session. However, the one document that in order to pull items a source(provider), we need to have a provider connector. The document also states that a Connector connects a Provider System with UWL and there exists several connector interfaces in UWL. We are only trying to connect to a simple Ad Hoc system but there isn't enough information available to us.

Any advice is appreciated.
