Yes, yes, no, yes. ;)
1. *Data.java classes are due to the <dataobject/> subtask
2. These objects are Data Transfer Objects in the DAO sense
3. Data Objects in XDoclet were replaced by Value Objects:
<valueobject/>
4. Same conceptual idea, different implementation
Are you creating your own DAO templates (complete implementations), or
are you hoping XDoclet will generate the DAOs for you? If the latter, I
believe that was the original intention of the <dataobject/> and
<entityfacade/> subtasks. Unfortunately, they have been deprecated but
only <dataobject/> got a replacement: <valueobject/>.
