Thanks a lot Erik, a very good start for me.

This is not a direct answer to any of your questions but perhaps it will
spur your thinking.
This is an example of using a custom ("pluggable") validator that makes
sure a date entry is not only a real date, but that the date is within a
desired range (seemingly you are wanting to do something similar to
this). I wrote this for Struts 1.1. I don't know if there is something
new and improved that would be better, but it works.
>From validation.xml (you'll see the use of the "date" rule -- which
uses the "datePattern" variable, as well as my custom "dateRange" rule
-- which uses the "minDate" and "maxDate" variables):
datePattern
MM/dd/yyyy
minDate
01/01/1900
maxDate
12/31/2030
>From validator-rules.xml:
classname="ValidationUtil"
method="validateDateRange"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionErrors,
javax.servlet.http.HttpServletRequest"
depends="required"
msg="errors.dateRange"/>
And finally the source of ValidationUtil:
import javax.servlet.http.HttpServletRequest;
import java.util.Date;
import java.text.SimpleDateFormat;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.validator.Resources;
import org.apache.commons.validator.Field;
import org.apache.commons.validator.ValidatorAction;
import org.apache.commons.validator.ValidatorUtil;
import org.apache.commons.validator.GenericValidator;
public class ValidationUtil {
public static final String DEFAULT_FORM_DATE_PATTERN = "M/dd/yyyy";
public static final Date DEFAULT_MIN_DATE = getDefaultMinDate();
public static final Date DEFAULT_MAX_DATE = getDefaultMaxDate();
public static boolean validateDateRange(Object bean, ValidatorAction
va, Field field, ActionErrors errors, HttpServletRequest request) {
//if we're not properly configured to parse dates,
//all date validation will fail
if (DEFAULT_MIN_DATE == null || DEFAULT_MAX_DATE == null) return false;
try {
String value = ValidatorUtil.getValueAsString(bean,
field.getProperty());
Date date = getDate(value, DEFAULT_FORM_DATE_PATTERN);
Date minDate = getDate(field.getVarValue("minDate"),
DEFAULT_FORM_DATE_PATTERN);
Date maxDate = getDate(field.getVarValue("maxDate"),
DEFAULT_FORM_DATE_PATTERN);
if (date.compareTo(minDate) < 0 || date.compareTo(maxDate) > 0) {
errors.add(field.getKey(), Resources.getActionError(request, va,
field));
return false;
}
return true;
}
catch (Exception e) {
e.printStackTrace();
errors.add(field.getKey(), Resources.getActionError(request, va,
field));
return false;
}
}
protected static Date getDate(String dateString, String pattern) {
Date date = null;
try {
SimpleDateFormat df = new SimpleDateFormat(pattern);
date = df.parse(dateString);
}
catch (Exception e) {
e.printStackTrace();
}
return date;
}
protected static Date getDefaultMinDate() {
return getDate("01/01/1900", DEFAULT_FORM_DATE_PATTERN);
}
protected static Date getDefaultMaxDate() {
return getDate("12/31/2030", DEFAULT_FORM_DATE_PATTERN);
}
}
Maybe you should browse the Struts wiki (wiki.apache.org/struts) for
example links?
Hope that helps some,
Erik
P.S. I never had much luck with DatePatternStrict, always wondered if it
was buggy . . . But I guess others are using it successfully?
