Re: Array of text fields generated dynamically - validation problem

[Nafise Dianatizade]

I have problem with array validation too, I can print the propety values in my action, 
but the validation doesn't work when I'm working with array type(ex. String[]). The 
validation of  "required" rule returns no error when it's empty.
 
Is there any special configuration for validating properties of type array?
 
Thank you
Nafise

Re: Array of text fields generated dynamically - validation problem

[Shyam A]

Hi,

I use a String[] in my form bean to handle a dynamic
array of text fields.

In my ActionForm, I have

private String[] candList;

public String[] getCandList()
{
return candList;
}

public void setCandList(String[] aCandList)
{
candList = aCandList;
}



In my JSP, I use

 

within a  tag.

My problem is that when a validation error occurs in
the validate() method of my form bean, the text fields
are populated with junk values. The text fields do not
retain the user entered values. However, the user
entered values can be printed out in the validate()
method.

How do I work around this problem?

Any help, suggestions/pointers will be greatly
appreciated.

Thanks,
Shyam

This is an interesting thing. Here is the way to avoid Struts calls  validate method 
on ActionForm

This one Struts framework will NOT call validate method on ActionForm



While this one does 



The only difference is if you do have property, Struts adds name="your_data". While if 
you don't have property set, Struts add name="org.apache.struts.taglib.html.CANCEL". 

Why these make the difference?

The Struts Validator provides a mechanism to deal with Cancel buttons. A
flag is set in the onclick method for the cancel button in the jsp page. The
validate methods check this flag and if it is set, they skip validation and
just return true.
 


If you're not using the Struts Validator, maybe you could try mimicking this
behavior in your validate method ??

I am wondering how to solve the following problem with a minimal amount

has three html:submit buttons -- Update, Cancel and Delete.   I am 
using a LookupDispatchAction and an ActionForm with the validation in 
the validate() method.  Under normal conditions everything works 
fine..But when a user clicks Update with invalid data on the form, 
the validate method catches the bad data and returns the proper error 
message.  If the user then decides to click Cancel (without changing 
the invalid data), the validate() method is still called and the user 
is returned the same error.


One thing that I might be able to do is to somehow find out what button 
was clicked in the validate() method...??  How would I do that, I

RE: Validation problem

[Robert Taylor]

What's the name of your "Cancel" button? Struts should not validate
if it finds org.apache.struts.taglib.html.CANCEL or
org.apache.struts.taglib.html.CANCEL.x

Take a look at the RequestProcessor.processValidate() code:

 if (request.getAttribute(Globals.CANCEL_KEY) != null) {
if (log.isDebugEnabled()) {
log.debug(" Cancelled transaction, skipping validation");
}
return (true);
}

That attribute gets set in RequestProcessor.processPopulate():

 // Set the cancellation request attribute if appropriate
if ((request.getParameter(Constants.CANCEL_PROPERTY) != null) ||
(request.getParameter(Constants.CANCEL_PROPERTY_X) != null)) {
request.setAttribute(Globals.CANCEL_KEY, Boolean.TRUE);
}

RE: validation problem

[Matthias Wessendorf]

mmm strange :-)

in your action
the is a blank
name = "loginForm"


try name="loginForm"


okay you have DynaValidatorForm
not DynaValidatorActionForm
(it´s sometimes not clear (the differents)...)

and you have

  

and NOT! name="/login"
(what is needed for DynaValodatorActionForm...




so please try to create an own bean
which extends DynaValidatorForm
and in its validator()
do some debug-output
(for seeing, validator-framework works...)

Re: validation problem

[Eric C]

Shouldn't your formbean type point to the actual class loginForm instead of
"org.apache.struts.validator.DynaValidatorForm", which i believe should be
in the bean code (bean extends DynaValidatorForm) ?

Aha, so all I need to do is change "datePattern" to "datePatternStrict"

Andy Schmidgall wrote:



   

datePattern doesn't work -- you must use datePatternStrict unless you
modify the javascript validation function.
This line is where the pattern is loaded:

var datePattern = oDate[x][2]("datePatternStrict");

Notice that it's loading datePatternStrict instead of datePattern from
the oDate object. The validation function completely ignores the 
datePattern var you defined in the xml.

You're getting the error because it's trying to load from the
datePatternStrict var which isn't defined, so the javascript 
datePattern var isn't a valid object.

I'm testing the JavaScript validation for my form and noticed that the
 

 

JavaScript generated to validate my date fields throws an error that I
 

 

can see in Firebird's JavaScript console. Here's the error:

datePattern has no properties

and here's the line it occurs on:

for (x in oDate) {

	var value = form[oDate[x][0]].value;

	var datePattern = oDate[x][2]("datePatternStrict");



  

 

	if ((form[oDate[x][0]].type == 'text' || form[oDate[x][0]].type
   

  

 

==

  

 

'textarea') && value.length > 0 && datePattern.length > 0) {
   

  

 

		var MONTH = "MM";

		var DAY = "dd";

		var YEAR = "";

I can see that my date fields appear correctly in DateValidations(),
here:
 function DateValidations () {

  this.aa = new Array("theStartDate", "Availability Start Date is
not a valid date.", new Function ("varName", 
"this.datePattern='MM/dd/yy'; return this[varName];"));

  this.ab = new Array("theEndDate", "Availability End Date is not a
valid date.", new Function ("varName", "this.datePattern='MM/dd/yy'; 
return this[varName];"));

 }

And in my validation.xml file, the following is defined:



	

	

		datePattern

		${defaultDate}

	





	

	

		datePattern

		${defaultDate}

	



Where ${defaultDate} is a global defined as:



	defaultDate

	MM/dd/yy



 

From what I can see in DateValidations(), it looks like the var-value 
   

is being picked up correctly ... so, I'm at a bit of a loss on this. 
Is
  

 



   

this a know bug in Struts 1.1?

Also, does using DynaValidatorForm with validation.xml and such *only*

No, you should be able to do both. I was just saying that if you had
counted on datePattern functionality, and you switch to
datePatternStrict, you may get slightly different results as they are
supposed to act slightly differently. :)

Re: Validation: Problem with datePattern and JavaScript

[Rouven Gehm]

Well yes this quick fix work, i have added the following :

var datePattern = oDate[x][2]("datePatternStrict");
if(datePattern == null) {

datePattern = oDate[x][2]("datePattern");

}

But the main problem is, the javascript code, afterwards still needs a

strict input (e.g. 01.06.2000)  and not checks if a not so strict

pattern (e.g. 1.6.2000) is a valid date.

So either someone already has coded the javascript, or else i'll do it


Thanx

It looks like the following line of code (in the date validator rule in
validator-rules.xml) loads the pattern:

var datePattern = oDate[x][2]("datePatternStrict");

As far as I can tell, nothing is ever loaded for plain "datePattern",
and this matches up with my experiences of using datePattern (i.e.
"datePattern" doesn't do any validation at all)

I haven't tried this, but it should probably be an easy fix to check if
oDate[x][2]("datePattern") has a value and load that into datePattern.

I want to know if someone has updated the javascript code
in the validate-rules.xml, for the datePattern option ?
Because the code i have from the Struts 1.1 zip only
work with datePatternStrict !!!

I have searched the user mailing list, for this problem, but
not found any solution.

It depends.. is the collection actually populated into the form? If so 
it should remain in the form when the validation is returned. My guess 
is you are talking about a collection that you put into request scope. 
In that case it's easiest just to put the collection into session scope. 
There are other ways around it, but session scope is the easiest. (If 
everyone using the app will need the same collection use application scope).

Re: struts 1.1 validation problem / question

[Phil]

Hi Andreas,

i think the best way is to write your own
validate() method in your action form. There you
can easily check the value of the userAction attribute
and depending on that the other attributes.

example:

public ActionErrors validate(ActionMapping mapping, HttpServletRequest
request) {
  ActionErrors errors = new ActionErrors();

  if (getName().length() < 1) {
   errors.add(ActionErrors.GLOBAL_ERROR, new
ActionError("form.error.name.required"));
  }

  return errors;
 }

Re: struts 1.1 validation problem / question

[Andreas Wuest]

Hi Victor,

thanks for you reply.  the lookupdispatchaction does not really solve
my problem, since handling the different actions is not the problem.
the problems is the validation of the input fields for the different 
action. i need different validations depending on the value of the
userAction html form value.

thanks, 

 Andreas

Oi Andre, 

Tries to verify the LookupDispatchAction class, this
class allows to manage diverse actions in simple
Action and in this way you can better manage its
validations with the Validator.

Good code.

struts 1.1 validation problem / question

[Andreas Wuest]

Hi,

i have a small problem / question concerning the struts 1.1 validation.
i have a jsp form that has the following input fields : 

id
name
password
userAction

Depending on the userAction value (can be 'show' or 'save') i need to 
validate only the id (when userAction is 'show') or the name, password
and id (when the userAction is 'save').
i have one form that contains the 4 properties (with getters and setters)
and an action class that handles the show and the save action. 

the problem that i have is the validation. as far as i understand the 
docuemtneation it is not possible to validate a property only when
another property has a certain value. in other words it is not possible
to tell the validator to skip validation of a property when another property
has a certain value. 
or am i mistaken ?

how can i solve this problem ? do i need 2 forms and action to handle the
different userActions or is there another way ??

Thanks in advance,

 Andreas

Hi,

I'm doing upgrade from 1.1 beta to 1.1 final and I found some problems with
validation.

In 1.1 final is not required to call explicitly validate when using
DynaValidatorActionForm. This is great.

But now when the page is not it sends a NullPointerException executing , and
not uses the initial value specified in struts-config.

java.lang.NullPointerException
at
org.apache.struts.validator.DynaValidatorForm.validate(DynaValidatorForm.jav

Any clue or this is supposed to happen?

RE: multi-form page validation problem (client side)

[Sieber Martin]

Maybe I didn't make myself clear. This is not about the static code, but
about the dynamic code. If you read my original posting, than you will
see that I have put the static JavaScript already to false:

However my mail prog removed the line brakes and therefore this wasn't
readable well. Apologies for that.

My problem is, that all the dynamic functions overwrite each other: 
mask(), maxlength(), ... are dynamic parts of the JavaScript, since the
ApplicationProperty labels are generated in there e.g.:
function maxlength () {
 this.aa = new Array("businessName", "BusinessName shouldn't be
longer than 50 characters.", new Function ("varName",
"this.maxlength='50';  return this[varName];"));
 this.ab = new Array("surname", "Other Text", new Function
("varName", "this.maxlength='50';  return this[varName];"));
}

DynaForm mapped property client-side validation problem

[Steve Caswell]

Using Struts 1.1.0, I'm having a problem with client-side validation of a map-backed 
property on a DynaValidationForm. The Javascript fails because of naming the form 
field using the map syntax. Here is my configuration:

I have the following DynaValidatorForm configured in struts-config.xml:


  


I have the following validation defined for this form in validator.xml:


  

  
  

  


And on the .jsp:


ValueD: 

 


ValueE: 

 






The problem is that the client-side Javascript validation fails to complete because 
the dynamic Javascript that gets generated is:

function required () { 
 this.aa = new Array("valueC", "???en_US.valueC.prompt??? must be entered", new 
Function ("varName", " return this[varName];"));
 this.ab = new Array("valueD", "Value D must be entered", new Function ("varName", 
" return this[varName];"));
} 

The reason the Javascript fails is that the name of the field for the second line 
above should be "longmap(valueD)", but the html:javascript tag builds it with just the 
key name, so the validateRequired() function fails when it tries to find a field with 
that name ("valueD").

I've looked all around the documentation and the mailing list archives, and I don't 
see anything specific to this case. Am I missing something, or is this a shortcoming 
of the html:javascript tag?

TIA.

Re: validation problem

[salgado . pc]

Check in your validation.xml if the messages (arg0, in this case) that are
binded with your error message is correct...
maybe it always returns the same error... (have you checked filling other form
fields and checking if messages change)?

Without the xml validation rule it is the best i can do... hope it works.

Hi there,

this is my first post!  I have inherited a web-based struts
project that is frankly a mess...  I have managed to straighten
out most things except something that is driving me nuts - this
is the problem:

Validation - I have 3 fields that need to be validated - if I do not
enter anything on all three fields, validation happens - I display
the messages in the JSP using the  'loop'.
However, the problem occurs if I fill in one of the fields, it
STILL reports that the first field is in error (the other two
which are unfilled are in error alos - this is a good thing), even though
there is
a value there (the validation is simple 'required').  If I fill in
ALL THREE FIELDS, then validation is OK, and I go on to the next
page.  There seems to be almost some kind of a "caching" of errors
that is happening, and I don't know how to "turn it off".

Thanks Alex.

Re: ValidatorBaseForm - Re: validation problem

[David Graham]

The ValidatorBaseForm simply extends ValidatorActionForm - sorry I fergot
to add that...
Oh, that might be why they used /public/EventRegistration as the form name.  
Try extending ValidatorForm and using the bean name defined in 
struts-config.xml instead.

Re: validation problem

[David Graham]

I believe the form name must be the same as what you defined in 
struts-config.xml.  Try
 in your validation rules.

David

Well, this is what I inherited:

  

 
 
 
 
 
   mask
   ^[a-zA-Z]*$
 
 
   minlength
   2
 
 
   maxlength
   40
 
 

 
 
 
 
 
   mask
   ^[a-zA-Z]*$
 
 
   minlength
   2
 
 
   maxlength
   40
 
 

 
 
 
 
 
   minlength
   1
 
 
   maxlength
   40
 
 

	





The form-bean is:



type="ontario.exports.events.struts.EventRegistrationForm">



The EventRegistrationForm extends EventDetailsForm which in-turn
extends - ValidatorBaseForm
These classes appear extremely messy and very long...

Thanks, Alex.

Re: validation problem

[Aleksandar Matijaca]

Well, this is what I inherited:


  

 
 
 
 

 
   mask
   ^[a-zA-Z]*$
 
 
   minlength
   2
 
 
   maxlength
   40
 

 

 
 
 
 
 
   mask
   ^[a-zA-Z]*$
 
 
   minlength
   2
 
 
   maxlength
   40
 

 


 
 
 
 
 
   minlength
   1
 
 
   maxlength
   40
 

 







The form-bean is:








The EventRegistrationForm extends EventDetailsForm which in-turn
extends - ValidatorBaseForm

These classes appear extremely messy and very long...

Thanks, Alex.

Post the relevant section of your validation xml file and more info about 
your form.

David


Hi there,

this is my first post!  I have inherited a web-based struts
project that is frankly a mess...  I have managed to straighten
out most things except something that is driving me nuts - this
is the problem:
Validation - I have 3 fields that need to be validated - if I do not
enter anything on all three fields, validation happens - I display
the messages in the JSP using the  'loop'.
However, the problem occurs if I fill in one of the fields, it
STILL reports that the first field is in error (the other two
which are unfilled are in error alos - this is a good thing), even though
there is
a value there (the validation is simple 'required').  If I fill in
ALL THREE FIELDS, then validation is OK, and I go on to the next
page.  There seems to be almost some kind of a "caching" of errors
that is happening, and I don't know how to "turn it off".
Thanks Alex.

validation problem

Hi there,

this is my first post!  I have inherited a web-based struts
project that is frankly a mess...  I have managed to straighten
out most things except something that is driving me nuts - this
is the problem:

Validation - I have 3 fields that need to be validated - if I do not
enter anything on all three fields, validation happens - I display
the messages in the JSP using the  'loop'.
However, the problem occurs if I fill in one of the fields, it

RE: Validation Problem

[Bailey, Shane C.]

I didn't notice if you got your problem solved but it is a simple spelling
error:

   public void setField1(String feld1)
   {
this.field1 = field1;
   }

should be:

setField1(String field1)

Hi!

I now have a strange validation problem. I use this ActionForm class:

package com.mycompany;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionServlet;
import org.apache.struts.util.MessageResources;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import java.lang.String;

public class PostTestForm extends ActionForm
{
   private String field1 = "";
   private String field2 = "";
   private String field3 = "";

   private void checkForEmpty(String fieldName, String fieldKey, String
value,
  ActionErrors errors)
   {
if (value.trim().length() == 0)
{
 System.out.println(fieldName + value.trim().length());
 ActionError error = new ActionError("error.posttest.field.null",
fieldName);
 errors.add(fieldKey, error);
}
   }

   private void checkForLength(String fieldName, String fieldKey, String
value,
   int maxLength, ActionErrors errors)
   {
if (value.length() > maxLength)
{
 ActionError error =  new ActionError("error.posttest.field.length",
fieldName);
 System.out.println(maxLength);
 errors.add(fieldKey, error);
}
   }


   public ActionErrors validate(ActionMapping mapping,
 HttpServletRequest request)
   {
ActionErrors errors = new ActionErrors();

checkForEmpty("field1", "error.field1.empty", getField1(), errors);
checkForEmpty("field2", "error.field2.empty", getField2(), errors);
checkForEmpty("field3", "error.field3.empty", getField3(), errors);

checkForLength("field1", "error.field1.length", getField1(), 5, errors);
checkForLength("field2", "error.field2.length", getField2(), 5, errors);
checkForLength("field3", "error.field3.length", getField3(), 5, errors);

return errors;
   }

   public void reset(ActionMapping mapping, HttpServletRequest request)
   {
field1 = "";
field2 = "";
field3 = "";
   }

   public String getField1()
   {
return field1;
   }

   public void setField1(String feld1)
   {
this.field1 = field1;
   }

   public String getField2()
   {
return field2;
   }

   public void setField2(String field2)
   {
this.field2 = field2;
   }

   public String getField3()
   {
return field3;
   }

   public void setField3(String field3)
   {
this.field3 = field3;
   }

}

Everything works fine except the application always claims, that field1 is
empty
even if it's not. value.trim().length() always is = 0 with respect to the
field1.
The content of the HTML-Form looks like this:

<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>



  

  


  

  


  

  


  

  


  

  




What's wrong???

The author is incorrect.  Check out

I'll do soon. I getting acquainted with Struts working with the book
Professional Struts Applications. I still have 14 pages ahead the validator
framework. But before I jump to it, I'd like to understand why some
basics don't work to gain more confidence in the whole framework.

session)

They're being stored in the request. But wait a second. Why do you mean I
don't
need to implement the reset method? The guy in the book states:

"The reset() method is invoked only if the developer has declared that the
ActionForm
class should be stored in the request. This is necessary because Struts
maintains a cache
for each of the ActionForm classes. A single instance of an ActionForm 
class
can be
shared by multiple users for different reqests at different times. Hence,
the developer must
implement the reset() method to ensure that the end user never gets some
other user's
data"

How does this sound?

Well, these validations have already been coded for you and can be 
configured in an xml file by using the Validator.  I highly recommend you 
look into using the validator because it will save you a bunch of time.

Your problem may have something to do with setting the fields = "" in reset. 
 I would put a stdout call in reset to see when it gets called.  If your 
forms are stored in the request (and I maybe even in the session) then you 
don't need to implement the reset method at all.  It's really only needed to 
reset boolean properties.

field1 = "";
field2 = "";
field3 = "";
   }

   public String getField1()
   {
return field1;
   }

   public void setField1(String feld1)
   {
this.field1 = field1;
   }

   public String getField2()
   {
return field2;
   }

   public void setField2(String field2)
   {
this.field2 = field2;
   }

   public String getField3()
   {
return field3;
   }

   public void setField3(String field3)
   {
this.field3 = field3;
   }

}

Everything works fine except the application always claims, that field1 is
empty
even if it's not. value.trim().length() always is = 0 with respect to the
field1.
The content of the HTML-Form looks like this:

<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>



  

  


  

  


  

  


  

  


  

  




What's wrong???

It should be request.getParameter("page")

Dontcha hate that? If I had a nickel for every time I've done that...
well, I'd have like $.15, but still.

ActionErrors errs = form.validate(mapping, request);
if ((errs != null) && !errs.isEmpty()) {
saveErrors(request, errs);
}

See if that does the trick!

1. Your form fields can be found in the ActionForm
being passed in to the Action.execute() method.
2. you can save your errors in an
ActionErrors/ActionMessages like shown below from with
the execute method:

ActionMessages msgs = new ActionMessages();
msgs.add(ActionMessages.GLOBAL_MESSAGE,
new ActionMessage(Globals.NEW_PROCESS_ERROR_CREATE));
this.saveMessages(request, msgs);

RE: Multiple forms with same format and validation problem.

[Jason Long]

I am still having the following two problems:

Problems:
1. request.getAttribute("page") is returning null and I cannot use the
action form methods for inside this class even though it is being passed in.
   It does work with return new ActionForward("/itemConfig_6.jsp") hard
coded.
2. My form field values are filled in except the errors are not being
displayed an the page anymore.

Questions:
1. How do I access a form field value from within ItemConfigAction?
2. How do I send the ActionErrors back to the page for display?


Current inadequate solution:
I added a similar hidden field to each page as follows:


I also moved my validation to
   public ActionForward perform(ActionMapping mapping,
 ActionForm form,
 HttpServletRequest request,
 HttpServletResponse response)
throws IOException, ServletException {
errors = form.validate(mapping,request);
if(errors.empty()) {
  // Forward control to the specified success URI
  return (mapping.findForward("success"));
} else {
  return new ActionForward("/"+request.getAttribute("page"));
}
}

Could you just have the input page's path as a hidden form field and
create a new ActionForward in the Action rather than looking it up in
the mapping? You might need to play some games with the formbean.

RE: Multiple forms with same format and validation problem.

I moved my validiations to the action, and I am going to try to using the
hidden field to redirect back to the proper page.  Is there some other way
to detect the page that way orginally posted from, without using a hidden
field as suggested by Dave Newton <[EMAIL PROTECTED]>?

It has been recommended that ActionForm.validate() be
used only for trivial validations like the input
format, range etc. And these validations can be pushed
to the browser and caught there instead. The other
business validations are recommended to be done in the
Action classes like its been pointed out in the other
messages, that way you avoid this whole problem.

I have an application that creates hundreds of jsp/struts form pages in xml
format.  All pages have the same input fields, except that there is a
varying number of checkbox fields.  I specified the following action:



  


The problem is that there are many pages name itemConfig_X.jsp, but with
this setup it is constantly redirected to itemConfig_0.jsp when validation
fails.  I need to know how to make each page use itself for input.  I would
appreciate any advice.  This project is already running behind schedule, so
I need to resolve this problem quickly.

Client Side validation problem with Struts 1.1 RC1

[Camper Richard D]

I deployed the struts-validator.war file to both Tomcat 4.1 and
Websphere 5.0 (via WSAD 5.0).  I am not geting any client-side
validation. When I viewing source via the browser for the
jsRegistration.jsp page, I noticed that the page did not contain any of
the validator java script that the  tag should have generated.

If I remove the reference to the validator_1_0.dtd from the
validator-rules.xml and validation.xml files I.E delete
http://jakarta.apache.org/commons/dtds/validator_1_0.dtd";>

Then the client side validation works.

The only thing I can think of is that the particular key you're referring to

Did you switch to ActionErrors.GLOBAL_KEY or change your JSP code?

1)  If you changed your JSP to  or
something, keep this in mind: I use a class called "Constants" for each web
app and refer to Constants.LOGINERROR_KEY in my code, but I have to make
sure that my JSP has the correct text.  What is the name of the property/key
you're assigning the error to?

2)  If you shifted to ActionErrors.GLOBAL_KEY, are you sure your locale is
right and your Resource bundle has the appropriate text key?

Try throwing this code in your JSP:


  
ERROR:  Language independent messages not loaded -- contact
administrator
for assistance.

validation problem with JVM of j2sdk1.4.1_01

[Iris]

Hello,

I've spend hours to find why my validation suddenly doesn't work.
When I remembered that I've change my JVM j2sdk1.4.0 to j2sdk1.4.1_01,
effectivly if when I put back the JVM j2sdk1.4, the validation works again.

I doesn't find any bug report on this.
Is anybody else had a validation problem with the j2sdk1.4.1_01 ?

Commons FileUpload has a size threshold below which a part is retained in
memory, and above which it is streamed to disk, to prevent memory issues.
It also has another size threshold that determines the maximum total size
of a request that it will accept, beyond which it will throw up its hands
and refuse to process the request at all.

One approach that works is to write a simple file upload script in Perl.
This allows you to check content-type, size, etc. and reject the upload
before trouble happens. It is also platform independent to a "reasonable"
degree.


Unless I'm mistaken, the commons file-upload component can do this too. 
Am I mistaken?

You could have the user enter the meta data first, and then after it's validated let 
the user choose the file to upload.

  I have just written a document upload tool for a customer using the struts
  upload functionality.  My upload jsp consists of one form that is of course
  a multipart/form-data form.  The form consists of the file field along with
  other text fields where the user enters various information( owner, title,

  you submit the form struts immediately starts uploading the file before any
  of the other data in the form is validated.  So, in my case, the user tries
  to upload a large file but enters invalid information for the other text
  fields.  Struts then uploads the file before validating the form data.  So
  when the user corrects their mistake they have to re-upload the file yet
  again.  Is it possible to have the form data validated before the file is
  uploaded?  I would rather not use javascript for error checking.  Any help

Just to clarify the process, Struts does not upload the file, the browser
does. The file is part of the same request as the other fields in your
form - it's one of the -parts- in the -multipart- request, as is each of
the remaining fields. Struts can't start working on the request until it
is complete, including the file upload.

If you need to do validation before the file is uploaded, you either need
to use JavaScript in the browser, or use a separate page for the other
fields, so that you can validate them server-side before the file is
uploaded from its own page.

Struts file upload validation problem

[Poynter, Stephen]

I have just written a document upload tool for a customer using the struts
upload functionality.  My upload jsp consists of one form that is of course
a multipart/form-data form.  The form consists of the file field along with
other text fields where the user enters various information( owner, title,
etc.) about the file to be uploaded.  The problem I'm having is that once
you submit the form struts immediately starts uploading the file before any
of the other data in the form is validated.  So, in my case, the user tries
to upload a large file but enters invalid information for the other text
fields.  Struts then uploads the file before validating the form data.  So
when the user corrects their mistake they have to re-upload the file yet
again.  Is it possible to have the form data validated before the file is
uploaded?  I would rather not use javascript for error checking.  Any help
is appreciated.  Thanks...

validation problem: limit on the number of fields allowed in a form

[Daniel Bray (CAPE)]

I have a strange problem involving the validation of fairly big forms.

First a preamble: the form itself always has the same name, but the field
that it's validating won't be known until runtime. There are 366 fields per
version and there are at least four versions.

I had tried to get around this by auto generating a big validation xml file
where each  had a unique id that could be derived at runtime: the JSP
could populate a hidden field of the same name with the value being saved,
and so validation could be done.

This worked fine when I was testing it for a handful of fields, the problem
arose when I tried to create a validation XML file with 1,464 fields.

In the rendered HTML page, I get this:

function TAPMask () {
 this.aa = new Array(.);
 this.ab = new Array(.);
  ...
 this.zy = new Array(.);
 this.zz = new Array(.);
 this.null = new Array(.); // this ain't right
 this.aa = new Array(.);
 this.ab = new Array(.);
  ...
 this.uw = new Array(.);
   }

As you can see the variable names run out at "zz" and then roll over.

What I'm asking here is:
1. Is this a recognized bug, and if so, is there any ETA on when this will
be fixed?
2. Currently I'm using the following to include the validation client-side.
<%-- Struts validation --%>


I can't change the form name for each field, or even for each field group
(there's too many) but is there any way of defining multiple validation
files for a form and then telling the validator to use a specific file.


Thanks for reading this far.



from me, daniel.

date validation problem

[Nicolas Robert]

Hello,


I use struts validator to check if a date that's not required has a correct
format.

It's working fine, but if the user leave the date field empty and submit the
form, Struts generate an invalide date format error.

Here's the sample of my validator.xml file :

Please, could you tell me how to inform Struts validation system that we
only want to check if the date format is correct when the date is not empty?


Thanks

RE: date validation problem

[Peggy Davidson]

It was the struts.jar from 10/5. Applying an entire nightly for me seemed to
fix that issue but then I ran into other validation problems, so I reverted
back to just the struts.jar which worked fine.

Re: Form Bean Validation problem

[Ted Husted]

As Robert mentioned, the best practice is to declare all the ActionForm
properties as Strings or booleans. 

The purpose of the ActionForm is not to represent your business data. It
is to serve as a buffer for the HTML controls. HTTP is String-based, and
so the ActionForm properties need to be String-based too. Otherwise, as
you have discovered, invalid values disappear, and cannot be presented
to the user for correction. 

Once the String values have been validated, you can then transform them
to their proper type, and store them in a business bean designed for
this purpose. 

Another important function of the ActionForm is to serve as a firewall
between the Web users and the rest of your application. We have no
control over what insane values someone can toss at our actions via
HTTP. The ActionForm is a DMZ where we can accept whatever value is
tendered, but validate it before it passed along to business objects
(which tend to be more trusting).

  I use two variables in the bean for the same non-String

  class myForm extends ActionForm {

private String price;

public String getPrice () { return this.price; } 
  /* this is called by  */

public float getPriceAsFloat() { return this.priceAsFloat; }
  /* this is used in Action */
/* note no settter method for priceAsFloat */

public ActionErrors validate (...) {

  ActionErrors errors = new ActionErrors ();

  /* validate () is the perfect place to convert String

   */
  
  try {

RE: Form Bean Validation problem

[Robert Taylor]

Albeit crude, I think that declaring it as a String is the right thing to
do. The value is sent across the wire as a string and Struts attempts to
convert it to the proper data type using introspection. The advantage of
declaring it as a String is that you have more granular control over
validation as you have already mentioned. Once your form has properly
validated the field, then you can safely use Integer.parseInt() in the
Action class to convert it to the expected primitive value.

My forms are usually contain all String fields. I then use an exportObject()
which returns a value object with the data in the appropriate
native format (ints, floats, Date, etc...) I can then pass the value object
to a business delegate to perform any business logic processing.
I also have an importObject() which maps and converts the value object data
members into the appropriate String fields.

That's just my preference.

Form Bean Validation problem

[cool dude]

Hi,
   Here's a small problem that I'm facing. I have a
form which has an integer field, say a cost of some
item. Now, I need to do the validation for this
form-field to make sure that the user does not enter a
non-numeric data in this field. I have the form
containing this field as a primitive int. The problem
is that whenever a non-numberic value is entered the
value is reset to zero. This leads to two problems,
one it doesn't give me a chance to find out that the
user has entered a non-numeric value in my validate
method & secondly, I end up losing the value that the
user had entered & hence can't show him the value
back. The rather crude solution to this is to make the
numeric form-field value a String & do the check in
the validate() to find if a non-numeric value is
entered. But I'm not happy with this solution as it
requires me to decalre a field as string even when it
should have been an int or float ...

Is there any other way around this prob?

Thanx in advance,
VD.

The problem might be that your form is in the request scope and your
countries list does not get populated from the submitted data. I've
similar "problems" when I used the ActionForm for displaying read
only properties which did not have an  on the jsp page.

In request scope it works something like this:

The ActionForm instace (A1) is used to fill jour JSP. A1 has been
probably prepared by some Action. After delivering the response
(JSP) the instace A1 is forgotten and eventually garbage collected.

The teh user sumbits your JSP. New instace (A2) of your ActionForm is
created and filled with the sumbitted values. If the countries
list is neither filled in the reset() method, nor the constructor,
nor the sumbitted HTTP parameters, than it might be empty or null.

Because the instace A1 and A2 are different.

If the form is in session scope, than A1 is preserved.

Re: validation problem

[David Winterfeldt]

Is your bean:define inside your html:form tags?  If
the userForm doesn't exist, you would get a null
pointer exception trying to call it.  If this doesn't
help, seeing the whole form might.

validation problem

[Yuriy Zubarev]

Salutation to everyne!

I have a form (extends ActionForm) that has a property "countriesList"
which holds a list of beans. In jsp form page I have a code:



which is executed without problems when the page is shown first time,
but when I click submit without entering values into textboxes,
"valiate" method of my "UserForm" works out and redirects the flaw
back to "user.jsp" and here I get exception. Looks like "countryList"
property vanishes from "userForm".

  
<[WebAppServletContext(2485833,haa)] action:   Validation error(s), redire
cting to: /user.jsp>
  
<[WebAppServletContext(2485833,haa)] Servlet failed with Exception
java.lang.NullPointerException
