ActionForm Validation : Date restriction ?
Hi,
I have a form : "updateEvent", my ActionForm ("EventForm") only has got a
bean ("Event").
This Event bean has got one property : "EventDate" : a java.sql.date field.
My problem :
How can I check in my validate method if the user has really filled in a
date ?
Or am I limited to work only with Strings on the level of a form ?
Thanks !

Posted by David Winterfeldt <dw...@yahoo.com>.
The ActionForm is normally considered a step between
your pure data bean with class types like
java.sql.Date. So most getters/setters on the
ActionForm will be a String. Although for fields like
a checkbox or a select I use boolean or int
respectively. If you don't use String, then when
there is an error validating or setting a field you
can't return the value to the user as they entered it
for them to fix. So you would gather the information
from the form into the ActionForm and then when basic
validation like checking for required fields and a
phone number looks like a phone number you could copy
the values to a data bean with the correct class
types. A couple of people have posted transformation
packages that will perform these conversion between
the two objects for you. The links (among many
others) are posted here.
