Hi Kris,
I am happy to hear that you were able to solve your problem.
From Duet Enterprise 1.0 FP1 SP3 and SAP NetWeaver Gateway 2.0 SP5, you can now use the new Service Builder to create your OData service. You will enjoy the much simplified development process and all the features and generator build into the Service Builder. Once you have registered your OData Service then you move on to the BDC Browser to generate the SOAP web service and the BDC Model. I highly recommend to use this new development approach for all of your new development. Ideally try to install the latest SPs for Gateway and Duet Enterprise. Please take a look at the new Developer Guide, which outlines this new development approach (http://scn.sap.com/docs/DOC-33223).
Cheers, Alex
