private Date dateOfBirth;
private static final DateFormat dateOfBirthFormat =
new SimpleDateFormat("MM/dd/yyyy");public Date getDateOfBirth() {
return dateOfBirth;
}public void setDateOfBirth(Date dateOfBirth) {
this.dateOfBirth = dateOfBirth;
}public String getDateOfBirthString() {
return dateOfBirthFormat.format(dateOfBirth);
}
public void setDateOfBirthString(String dateOfBirthString)
throws ParseException {
this.dateOfBirth = dateOfBirthFormat.parse(dateOfBirthString);
}And then I use dateOfBirthString as the property in the <html:text> tag. I'll also create a rule in the validator to make sure that dateOfBirthString is the right format, so the ParseException never happens.

SimpleDateFormat and do the actual conversion when

HTH, -- Chris.
BTW, as such conversions are needed quite often, it's a good idea to write a small utility function that does the conversion check and put it in either your BaseActionForm or some general utility class.
Yeah, I guess I could do that. I think need 2 properties. I would
create a dateAsString property, have the form get and set that, and
then have the getters and setters set and convert the actual Date. This way I can call getDate to get a Date and getDateAsString to get
it as a formatted String.
Are their other ways to handle this, so I don't need 2 properties?

ActionForm has a object that has a Date property that I want to set.
So I have
<html:text property="object.date">
If I populate the that property in the Action like this:
MyObject obj = new MyObject(); obj.setDate(new Date()); form.setObject(obj);
The html:text tag does a toString() on the object.date property. How can I get it to display in the MM/DD/YYYY format instead?
Likewise, how
do I make it so the user can enter a date in the format of
MM/DD/YYYY and have it correctly set the Date property?
I'd have the getter format the Date as a string (use SimpleDateFormat.format(), you can specify any of a wide variety of formats). Likewise, the setter should accept a string and use SimpleDateFormat.parse() to turn it into a Date. If parse() returns null then the String could not be turned into a Date, and you need to display an error message.
