Validator Framework Questions
Hello!
Reading a Struts book I wanted to give the validator framework
a whirl. Since it's poorly described in the book I checked out
Struts website. I wonder if when we speak about automatic form
validation, then if do we mean the validator from the website
http://home.earthlink.net/~dwinterfeldt or has another
validator been integrated into Struts. How doI setup an
automatic form validation?
I've build a form with 3 fields called field1, field2, field3
and a submit button. I've defined the validation rules in the
validation.xml file, but this thing just doesn't work. Below
my setup.
my validation.xml looks like this:
form-validation
formset
form name=postTestForm
field property=field1
depends=required,maxlength
msg name=required
key=error.posttest.field.null/
msg name=maxlength
key=error.posttest.field.length/
arg0 key=myapp.posttest.form.titlelabel/
arg1 name=maxlength key=${var:maxlength}

Re: Validator Framework Questions
I think it is necessary to include a input property in the action element,
so if the data is invalid the controller can recall the form file (or
tiles action).
action
path=/nameOfAction
name=nameOfForm
type=package.package.class
validate=true
input=/file.jsp OR .tiles.action
forward name=key path=file.jsp OR .tiles.action/
/action

Re: Validator Framework Questions
The Validator framework (commons-validator) comes with the struts
distribution.
To install it you will need: jakarta-oro, commons-beanutils,
commons-logging, commons-collections, commons-digester.
Put these files (.jar) on your WEB-INF/lib (if you already installed
struts it will only be missing the jakarta-oro.jar and
commons-validator.jar).
Configure your validation-rules.xml , validation.xml (better have an
example to start with... And download the dtds of these files... You may
need them.) and configure your struts-config.xml (the one had you seemed
ok).
Place the dtd files on a webapp directory (for example: /WEB-INF/dtd).
Change the validation-rules.xml and validation.xml DOCTYPE element (in
case you are developing without an internet connection, at the server
startup it tries to validate the 2 files - tries to retrive
http://jakarta.apache.org.../file.dtd - if the container doesnt find
these files an error occurs )...
Example: for validation.xml
?xml version=1.0?
!DOCTYPE form-validation
SYSTEM
/Library/Tomcat/Home/webapps/mywebapp/WEB-INF/dtds/validation_1_1.dtd
form-validation
...
/form-validation
You also have to include some properties on your webapp message resources:
errors.required={0} is required.
errors.minlength={0} can not be less than {1} characters.
errors.maxlength={0} can not be greater than {1} characters.
errors.invalid={0} is invalid.
errors.byte={0} must be a byte.
errors.short={0} must be a short.
errors.integer={0} must be an integer.
errors.long={0} must be a long.
errors.float={0} must be a float.
errors.double={0} must be a double.
errors.date={0} is not a date.
errors.range={0} is not in the range {1} through {2}.
errors.creditcard={0} is an invalid credit card number.
errors.email={0} is an invalid e-mail address.
These were all the steps I had to make...
Good luck :)

Re: Validator Framework Questions
Thomas, I have seen may developers struggling with Struts Validation (IMHO, it is a GIFT to us). The best way is to read some good book like the one from Chuck Cavaness. I read it once and my validation never fail me. Or you can view his article http://jakarta.apache.org/struts/resources/articles.html -Dan - Original Message - From: Thomas Miskiewicz [EMAIL PROTECTED] Newsgroups: Struts Sent: Sunday, June 15, 2003 10:09 AM Subject: Re: Validator Framework Questions Dan, change your strut config to use org.apache.struts.validator.DynaValidatorForm That helped.
