Thank you solved my problem, I did not realize that the namespace gets lower cased when generating the package.
The oddity with the top level namespace is my attempt to obfuscate my company name for the purpose of posting the question on this forum. The other oddity, the Registration attribute is used in some java examples which I did not clean up before posting the question. This is my first app so I am in the middle of a long learning curve.
