I've tried this code with both 2.2 and 2.3.1 and I'm getting an error from Jeryey on the get02 resource method.

WARNING: The following warnings have been detected: WARNING: A HTTP GET method, public java.lang.String com.example.MyResource.get02(java.lang.Integer,java.lang.String), should not consume any entity.
