RE: Am I the only one using java.util.Date?
If you search the list archives at www.mail-archive.com, I think you will find your question answered. Pappa Struts (Craig) answered it, as did other folks.

Re: Am I the only one using java.util.Date?
Since I'm connected to jboss I use java.sql.Date. Then I pass values in millis and use a GregorianCalendar to manage dates.

RE: Am I the only one using java.util.Date?
When you input or output dates you should java.text.SimpleDateFormat format and parse functions to convert to and from a known format string like -MM-dd that you can maintain in a ResourceBundle. Tell the user which format you expect by rendering todays date with the format string.

Re: Am I the only one using java.util.Date?
Rick,
You are on the right track. A suggestion would be to break the month, day
and year out on your forms (makes nice-nice with html:select) and provide
the code to populate them in your form instance. The conversion is actually
quite simple:
public GregorianCalendar getStartDate()
{
return new GregorianCalendar( this.getStartYear(), this.getStartMonth()-1,
this.getStartDay() );
}
This getter (exists in the same form instance) will hand off the startDate
as a java.util.Date to your (dyn)Action.
HTH
Brian

RE: Am I the only one using java.util.Date?
If you are using struts 1.1 and validator framework, StrutsValidator.validateDate converts the string to a java.util.Date and returns this Date. This returned value gets saved on the validationResults in the ValidatorForm. ValidatorForm.getResultValueMap() returns a HashMap containing these converted values associated to each form property that is being validated/translated. I am not using 1.1 yet, but used the same approach in 1.0 by extending struts validator framework to do my form property conversion. -Padma -Original Message- From: Rick Reumann [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 16, 2002 12:22 PM To: Struts List Subject: Am I the only one using java.util.Date?
