Hey I looked recently at the naming at J2EE Patterns of Sun. 

They switch from VO to Data Transfer Object

What will be the next month name ?  Bets are open.

Imho we should use what Floyd uses in his EJB Patterns book.

Thanks.  That makes sense.  Martin Fowler uses the name

Data Transfer Object for the Sun pattern Value Object.

 

Has the Java community settled on the name Value Object,

or might the name Data Transfer Object be more appropriate

for XDoclet?

 

I don't really care one way or the other, I'm just trying

to stick my finger in the air to see which way the wind

is blowing.  ;-)

 

Tx!

DO is the same concept as VO.

VO will replace DO in the future.  More powerful.

What's difference between data object and value object
in XDoclet?

I've found documentation for the Value Object pattern
(http://java.sun.com/blueprints/patterns/j2ee_patterns/value_object/index.html)

and for the Data Access Object pattern
(http://java.sun.com/blueprints/patterns/j2ee_patterns/data_access_object/)

But I can't find a definition of the "Data Object" pattern.
It seems that in XDoclet the <dao> subtask is different
from the <dataobject> subtask, so am I correct in assuming
the dao and dataobject don't have anything to do with each
other in XDoclet?

Thanks for any enlightenment!
JD
