Re: Validation Question how to echo back users input in error message?
The short answer is that there isn't a way to echo back user input in the
error message. Most of the time I don't think its necessary to do so
anyway - since if you're re-displaying/highlighting errors then what is the
need. The one time I scenario I wanted to do something like that, was when I
had a list, say for example you are displaying a list of orders and you want
a message along the lines Order date for order number 1234 is invalid -
where the order number 1234 is a value from the list.
There are two places that I know of, where this kind of functionality has
been provided. The first is in the extends validator I wrote (see the
indexed example):
http://www.niallp.pwp.blueyonder.co.uk/strutsvalidatorextends.html
...and the other place was in the javascript validator extension I started
work on:
http://www.niallp.pwp.blueyonder.co.uk/validatorjs.html
Hopefully, one day I will find some time to work on validator to make these
kind of features standard - but for now theres nothing out of the box to
meet this requirement.

I would like to know the answer on this too. I searched the Net, all
examples use properties from property file. Using resource=false
does not help with either (neither?) of these variants:
arg0 key=nestedUser.fromAddress resource=false/
arg0 key=${nestedUser.fromAddress} resource=false/
arg0 key=registrationForm.nestedUser.fromAddress resource=false/
arg0 key=${registrationForm.nestedUser.fromAddress} resource=false/
where registrationForm is action form definition in struts-config.xml,
nestedUser is a nested BO. Originating mail address is rendered in
HTML and submitted back to application as nestedUser.fromAddress.
Commons Validator does not process HttpServletRequest (that is
expected). I glanced at ValidatorForm from Struts Validator
integration, and saw this validate() method:
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
ServletContext application = getServlet().getServletContext();
ActionErrors errors = new ActionErrors();
String validationKey = getValidationKey(mapping, request);
Validator validator = Resources.initValidator(validationKey,
this, application, request, errors, page);
try {
validatorResults = validator.validate();
} catch (ValidatorException e) {
log.error(e.getMessage(), e);
}
return errors;
}
So, maybe you want to debug this one.
Commons Validator basically does not have documentation, only
Javadocs, which is not very descriptive. No comments in the source,
either. This is frustrating.

I am using the struts validator and it works almost exactly the way I

Say I have a field tf and the value is ABC
I want to do a validation requiring it to be an integer and return the
following error message: tf must be an integer.
I can do all this pretty easily here is the code that does it:
in ApplicationResources.properties :
validation.error.acty.integer={0} must be an integer and {1} is not.
in validations.xml
field property=acty depends=integer
msg name=integer key=validation.error.acty.integer/
arg0 key=ACTY resource=false/
arg1 key=${??} resource=false/
/field
my question is what do I put in ?? to get hte actual value the user
entered to be echoed back out
so if I type in AAA into the acty field I want the error message to be:
ACTY must be an integer and AAA is not.
Thanks Troy
