I don't think so. You see, with per alias or per method validation, you
can have multiple xml files for the same action with the filename
format : ActionName-alias-validation.xml

e.g.: 
if I have defined my action like this :

View1.jsp
View2.jsp
View3.jsp


I can per alias validation. As I'm using wildcards, it is as if I
defined CycleManagement!A action and CycleManagement!B action ...

So I can have :
CycleManagement-CycleManagement!A-validation.xml
CycleManagement-CycleManagement!B-validation.xml
CycleManagement-CycleManagement!C-validation.xml

I don't see how implementing Validatable allow me such a thing. I will
only have one Validate() method (without parameter) for my action class.

No ? Am I missing something ?

I haven't used it myself, but the syntax validate-action is suppose to
work, in the same way that it works for the validation framework.

Firstly, thank you very much for your answer :)

Ok then... That what I though... But my problem is that Validate() is
called every time no ?
I mean, I currently use action like that :


View1.jsp
View2.jsp
View3.jsp


and I have per-method validation...
Is it possible with Validate() ? How can I do ? (I think it's possible
with ActionContext.(... get current method...))

Of course yes :-). But I need a validate() per method.

So for me it seems the better choice would be type converter ? what do

Rather than use the validation framework, I'd probably go with a
Validate method (by implementing Validatable).

Then, instead of using an OGNL expression, you can loop through the
list using Java, and call addFieldError if there's a problem.

Alternatively, a custom type converter that turned the nulls into
false booleans might work, or there might be another way to form the
OGNL expression. But given the choice between OGNL and Java, I'll take
Java. :)

Re: Validation Question how to echo back users input in error message?

[Niall Pemberton]

Not from the request - from the form bean (or indexed Bean) - in this
example lineNumber needs to be a property of the indexed bean.

Are you saying that it will take a real lineNumber from request? How
does it know to get if from request? Does it just checks if request
has this key, and if not, goes to the property file?

Re: Validation Question how to echo back users input in error message?

[Niall Pemberton]

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:






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.

Re: validation question...

I would like
to automatically place a little red * right beside the input field.
For my password confirmation field, wnen I put

beside the text field, I get the WHOLE STRING for the 'required' 
validation,

instead, I would like to display only a *.


The  tag might help...
http://struts.apache.org/userGuide/struts-logic.html#messagesPresent

There are also 'errorStyle' and 'errorStyleClass' on the  tags.  If 
you can do it in CSS, you can apply it to the form element _only_ when there 
is an error for that property.

You could add errorClassId on the input element and use CSS to insert an

an error exists for a particular property though. This might work (haven't

You can do it both ways.

Use validation.xml, but ALSO define your own validate() that checks the
"should I validate property".

All you have to do to get the validation framework to do it's thing is to
call super.vallidate() in your own validate() method.

Joe, do u mean checking the field with "validwhen" using validation.xml or
implement the actionForm.validate() ?
I really want to use the basic struts validation framework instead of
implementing validate() function to minimize the maintainence cost.

In practice, it's rare that you actually have a webapp where every single 
page is sometimes accessed as the result of a form submission and 
sometimes as a simple HTTP GET.  And especially unlikely that you would 
have this to the scope where the actual dual maintenance is a serious 
burden.  At least, in my experience, this is simply "the right way to do

On the other hand, if you actually have this situation, you don't have to 
turn off validation -- simply implement your validation rules so that they 
can recognize the distinction.  For example, have all your forms submit a 
hidden field, and have your validation method only evaluate its validation 
rules if that field has a defined value. When the page is retrieved 
without a form submission, this value is not going to be defined.

Remember that you can implement the "validate()" method of your 
ActionForms anyway you like.

Uhm ... don't think so.  You could have a simple forward setup for the 
initial display of the form.  Then, have your actual "meat and potatoes" 
action.  That's two actions alright, but you only need to code one of them 
...

Realize, when many say "an action", they mean an entry in the XML file. 
Sounds to me like you're thinking two seperate classes.

2) Turn validation off, and handle that in the action:
then I've to give up struts validation framework
Yep.  ... but you wouldn't have to have the extra action mapping.
I think these 2 suggestions are simple workaround for this problem,

it will break the framework in some degree
Is there any other solutions come with Struts??
Nope.  Perhaps in time the Validation framework will evolve to be smart 
enough that it "knows" (or can) that it doesn't need to validate the form on 
the first display.  I'm actually kind of surprised this behavior hasn't been 
added in by now.  Seems it would be simple enough to do, but, perhaps I'm 
oversimplifying in my head.

Thanks!

In practice, it's rare that you actually have a webapp where every 
single page is sometimes accessed as the result of a form submission 
and sometimes as a simple HTTP GET.  And especially unlikely that you 
would have this to the scope where the actual dual maintenance is a 
serious burden.  At least, in my experience, this is simply "the 
right way to do it."

On the other hand, if you actually have this situation, you don't 
have to turn off validation -- simply implement your validation rules 
so that they can recognize the distinction.  For example, have all 
your forms submit a hidden field, and have your validation method 
only evaluate its validation rules if that field has a defined value. 
When the page is retrieved without a form submission, this value is 
not going to be defined.

Remember that you can implement the "validate()" method of your 
ActionForms anyway you like.

Re: validation question

[Yves Sy]

Hi,

Struts doesn't have anything like that.

IMHO, I also think that using validator on the login page is not good
practice as it would give malicious users a good idea on how your app
handles authentication.

Usually, you'd just return a generic error message such as
"Username/password invalid" whenever login fails (or in your case, the
user directly types /login.do in the browser). Try not to give out any
information as much as possible.

Regards,
-Yves-
