RE: help please: Validator basic use
Try applying a simple validator like required to one of your form fields, if
it does not work verify the following.
1. name used in the validation resource file matches the name in your action
mapping
2. validate set to true in your action mapping
3. your form extends ValidatorActionForm, and if you have any custom
validation in your form, you don't ignore the errors returned by
super.validate.
If the problem is only with date validator, are you entering this garbage
after you enter a valid date?
The date validator that comes with struts1.1 uses a short pattern (M/d/YY
for en_US) if you do not explicitly pass a valid date. It does not do strict
parsing by default unless you specify pattern using the variable
datePatternStrict.
If you want to implement strict date parsing with out having to specify this
pattern, write your own pluggable validator and check for the parse position
DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT, locale);
df.setLenient(false);
ParsePosition pos = new ParsePosition(0);
Object obj = df.parseObject(value, pos);
if (pos.getIndex() == 0)
throw new ParseException(Unparseable value: \ + value + \ ,
pos.getErrorIndex());
if (pos.getIndex() value.length())
throw new ParseException(Unparseable value: \ + value + \ ,
pos.getIndex());

Subject: help please: Validator basic use
Hi I am attempting to use the date validation provided by the framework - I
am using struts1.1b2.
I think I must be missing something fairly fundamental but maybe someone
will be able to confirm what that is. The problem is when I enter garbage
into the form's date fields and submit them, I get no errors. How does one
usually display the errors when using the validator framework.
I have my validator-rules.xml and validation.xml config files in my
application's web-inf dir.
Their relevent contents are as follows:
validator-rules.xml
validator name=date
classname=org.apache.struts.util.StrutsValidator
method=validateDate
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.date
jsFunctionName=DateValidations
javascript![CDATA[
function validateDate(form) {
... etc
return true;
}]]
/javascript
/validator
and validation.xml:
formset
form name=ReportForm
field property=dateFrom depends=date
arg0 key=ReportForm.dateFrom/
/field
field property=dateTo depends=date
arg0 key=ReportForm.dateTo/
/field
/form
/formset
I have my action's validate attribute set to true.
Are the above setup correctly?
Thanks
Jim

RE: help please: Validator basic use
Hi,
I eventually got it to work. I had not seen the example struts-validator.war
and when I did some comparisons, I found that I was misinterpreting the way
in which the form validation was defined in validation.xml.
Its working now - thanks for the input!
Jim

Re: help please: Validator basic use
Is your form derived from ValidatorForm rather than ActionForm?
