When I first started developing with Struts (pre 1.0), I'd just have a

simple form with a DTO (VO back then) as a getter/setter on my form. In the

last year, I've changed to have a DTO and a Form, where the DTO has the true

data types (Long, Date, etc) and the form has only Strings. After doing it

both ways, it seems like the DTO as a getter/setter is really the better way

to go. I'm not trying to say it's the *right* way according to the design

patterns, I'm just offering my $.02 from experience. I continue to do it the

BeanUtils.copyProperties() way, but the projects I work on that do it the

other way seem cleaner.

Conversion -> UserManagerImpl.java (source: [http://tinyurl.com/emof] - see convert() method). This extends BaseManager ([http://tinyurl.com/emok]), which registers custom converters. No DateConverter in this example, but I've done it at my day job, so I know it's fairly easy.
