OK. I think maybe the terminology is getting mixed up. I go into Cognos Administration -> Configuration -> Data Source Connections. That is what I want to create. A Data Source Connection, a dataconnection, and a signon.
The SDK java code that I downloaded that had the xml file I think is adding a Data Connection to be used in Report Studio, or something like that. I am not sure, except the testdata.xml file provided looks like just general information for camping equipment sales. I guess DAta Source Connection has a bunch of different meanings.
Anyway, I want to use the SDK to create a Cognos Administration -> Configuration -> Data Source Connections. That is what I want to create. A Data Source Connection, a dataconnection, and a signon modeled after an existing DSC. Thanks.
