With all due respect to apachep2 I would store myDate as a String in an ActionForm bean and then in your business class you store your Date as the Date you want (I prefer java.util.Date). So now the question becomes how do you quickly copy all of your String form bean properties into this business bean that has a type: java.util.Date.\ In your action you submit to you do: BeanUtils.copyProperties( yourBusinessBean, yourActionFormBean ) BUT, as you have realized copyProperties will not work for java.util.Date. So you need to register a converter. I posted about this a while a back and a search of the archives reveals the link below. I would change one thing though... following Craig's suggestion it's cleaner to register the converter as a Plugin which you can do easily in your struts-config file. Since all my DispatchAction classes extend a BaseAction I registered the converter there in a static block, which works, but it's just cleaner as a Plugin since you could easily swap out the converter at a later time. Let me know if this link helps. If you are still having trouble let me know. http://marc.theaimsgroup.com/?l=struts-userm=103487187525032w=2 -- Rick Reumann - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Here is what I do. The client enters a date of birth date as a string on
the
form, then I convert it to a java.sql.Date object in this method.
/**
* Sets the dobStr
* @param dobStr The dobStr to set
*/
public void setDobStr(String dobStr) throws
java.text.ParseException {
this.dobStr = dobStr;
// reset the Date object
this.dobDate = null;
if ((dobStr != null) (dobStr.length() 0)) {
SimpleDateFormat sdf = new
SimpleDateFormat(MM/dd/yy);
sdf.setLenient(false);
try {
java.util.Date dt = sdf.parse(dobStr);
this.dobDate = new
java.sql.Date(dt.getTime());
} catch (ParseException pe) {
throw new java.text.ParseException(Date
Of Birth:,
pe.getErrorOffset());
}
}
}
