Re: Difference between DynaValidatorActionForm and DynaValidatorForm

[David Winterfeldt]

The key used to look up a set of validation rules is
different.

DynaValidatorForm 
--
The key passed into the validator is the action
element's 'name' attribute from the struts-config.xml
which should match the form element's name attribute
in the validation.xml.


DynaValidatorActionForm 

The key passed into the validator is the action
element's 'path' attribute from the struts-config.xml
which should match the form element's name attribute
in the validation.xml.

Re: Validator use of JavaScript

[David Winterfeldt]

It is just an option to have JavaScript validation. 
The JavaScript methods perform the same logic as the
java methods that are referenced. The server side
validation is always performed if you have everything
setup correctly and the JavaScript is just to enrich
the user's interface.

RE: Validator

[David Winterfeldt]

You can go to my site to.  I have older downloads and
revision notes posted.  The version 1.0 under the
downloads (same as July 2001 release) was the last
version developed with Struts 1.0, but you can get
some later versions working with a little more effort
(getting all the extra jars).  

http://home.earthlink.net/~dwinterfeldt/


You can look at the revision info to see the changes
between the posted jars.  And all current work is in
CVS with Struts and the Commons Validator.

Re: Validator error

[David Winterfeldt]

I think you may have upgraded the Commons Validator
jar, but not Struts.  The SERVLET_CONTEXT_KEY was
removed from this class to try to completely separate
it from Struts and the web layer.  Try using the
Commons Validator that comes in the nightly download
for the version you are using.

Re: 6-22-02 Validator Nightly set-property confusion

It should be a comma delimitted list with the
'pathnames' property.  It was only the other way for a
few days, but unfortunately it made it into the beta.

RE: Validator problem (or user problem... not sure which yet)

[David Winterfeldt]

The change from using multiple set-property elements
was made right after beta since it wasn't very clear
to call setPathname muliple times.  The Validator is
run through the ActionForm's validate method and
returns a standard ActionErrors object.  The
additional tags that used to come with the Validator
were for features now incorporated into Struts.

html:messages - Iterate through messages/errors.

logic:messagesPresent - check for the presence of a
message/error (can pass in an optional property to
check if there is a message/error for an individual
field)

logic:messagesNotPresent - check for the absence of a
message/error

RE: Validator for Struts 1.02

[David Winterfeldt]

The 7/2/2001 release is the Struts Validator 1.0
release to go with the Struts 1.0 release.  I even
have a 1.0 download which is just the 7/2/2001 release
zip renamed.  The 7/2/2001 release is very stable.  A
lot of people were using it with no bug reports for a
long time.  And even subsequent work done on it for
months was very minor until I started making the
Validator work with the Struts nightly builds.

Re: Struts Validator and global commands

[David Winterfeldt]

If you are referring to redefining forms between
locales, you only need to override change from the
default locale (no language or country defined).  So
if the default locale has first name, last name, and
phone number and you wanted a different phone number
mask for french.  You would just have to create the
form with the same name and duplicate the phone number
field with the different mask.  

If you want to actually create shared groups of fields
for something like an adddress, you can't currently
create fields in the global section.  I want to do
that though.  So it will be something that eventually
gets done.  Then you could create a field set for
something like an address and reuse it.  But right
now, you will need to duplicate similar fields between
different form elements.

Re: Validator and DispatchAction

[David Winterfeldt]

Actually, I think I take that back.  You want to
actually skip certain fields if it is an insert or a
delete.  Making a method validation that returns false
(fails) will stop all validation.  You really probably
want a dispatchMethodRequired validator and any other
ones so they skip that validation if it shouldn't be
checked.  The other Validator methods kind of work
like this with required.  Everything else depends on
required, but if you remove the dependecies all those
methods, like mask, check if the field isn't blank
before they perform the validation.  If it is blank,
mask returns true and doesn't really do anything.

Re: Validation with multiple string files

[David Winterfeldt]

There isn't a way currently.  Could you file a
bug/enhancement a on this in buzilla?  That way your
request won't get lost.

Re: Validator and DispatchAction

[David Winterfeldt]

You can't use booleans in the depends, but there can
be dependencies setup between validation routines. 
You can make a method check pluggable validator and
have required and other validator depend on it. 
Although the default configuration has everything
depend on required so if required depends on something
else, everything should work fine.  Method would be
checked first and then if it passes required would be
next.

Re: Indexed Property Validation on a String[]

[David Winterfeldt]

There is an example of this in the Validator example
webapp in the type.jsp page in the nightly builds
using an ArrayList, but I believe everything should
work for an array too (or you could use
java.util.Arrays to convert to a Collection if you
need to).

Re: Struts Validator 1.1

[David Winterfeldt]

Creating a Separate Page for Static JavaScript
If you want to just generate the dynamic JavaScript on
you form page and have a separate page with the static
JavaScript to take advantage of browser caching you
can use the dynamicJavascript and staticJavascript
attributes to the JavascriptValidatorTag. You can turn
each attribute's generation of JavaScript on and off
by putting in true or false (they default to true).
Reference jsType.jsp and staticJavascript.jsp in the
main example webapp for a working example.

In your form page:



This wouldn't work right in IE 5.0 when I made the
source an attribute of the tag.

In your static JavaScript page.
<%@ page contentType="application/x-javascript" %>


http://home.earthlink.net/~dwinterfeldt/jsptags.html

There is an example of this in the example webapp.

Re: Validator and DispatchAction

[David Winterfeldt]

You would currently have to write your own required
validation method and have it check a variable defined
by a field to see if it should perform the validation
or not.  Or define a separate set of validation rules
for each action and use ValidatorActionForm (which
uses the action path to retrieve the validation
rules).

Re: R: validator generated HTML code

[David Winterfeldt]

It makes it very difficult to debug the JavaScript
when all whitespace is stripped out.  The best thing
to do if you are concerned about the extra download
size of the web page (I am assuming this is the
concern) is to make a separate page for the generic
JavaScript functions.  There is an example of this in
the Validator webapp.

Creating a Separate Page for Static JavaScript
If you want to just generate the dynamic JavaScript on
you form page and have a separate page with the static
JavaScript to take advantage of browser caching you
can use the dynamicJavascript and staticJavascript

developed with Struts 1.0.

I'm working on it for the Struts 1.1 and Commons
Validator release.  The current nightly build give
access to any transformed data in a Map, but there
isn't anything like this for older versions.

Struts Transformer by Ron Smith - Transformations are
responsible for taking an object in one form and
transforming it into another.(e.g. Date object to
String; String to Date).

This wasn't added until 6/17/2001.

Update 6/17/2001 (using Struts 1.0)
A bCancel variable was added to the
JavascriptValidatorTag code generation so the onclick
attribute of the html:cancel tag can be assigned
"bCancel=true;" so the JavaScript validation isn't
performed and the onclick attribute of a html:submit
tag can be assigned "bCancel=false;".

Re: DynaValidatorActionForm/DynaValidatorAction

[David Winterfeldt]

DynaValidatorForm just extends DynaActionForm and
overrides the validate method.  From a discussion on
the dev list I was under the impression that it would
work the same, but I didn't have time to test them or
make examples.  I was rushed to get them into the
beta.  If you can't just replace DynaValidatorForm in
a working DynaActionForm, could you file a bug in
bugzilla so it doesn't get missed and definitely gets
fixed for Struts 1.1?

http://nagoya.apache.org/bugzilla/

ValidatorForm & DynaValidatorForm use
mapping.getAttribute() to retrieve the form

DynaActionForm & DynaValidatorActionForm use
mapping.getPath() to retrieve a form

Re: Validator within Struts 1.1

[David Winterfeldt]

Are you still using the your old validator definitions
in the validations.xml?  It would be good to switch to
using conf/share/validator-rules.xml.  You can either
cut and paste them into the top of your old file or
leave them separate and erase the old ones.  

for beta:

   


as of nightly build from a one night ago (comma
delimitted):



You would also need the Commons Validator jar when
using the new classes.  Also, are you extending
org.apache.struts.validator.ValidatorForm and not the
old one?

Also as of last night the Validator is using Jakarta
ORO instead of Jakarta Regexp.  I think it might have
broken the nightly build last night, but I'm sure it
will be fixed soon.

Re: validation plugin

[David Winterfeldt]

After the bean is populated from the request.  Then
the validate method in the ActionForm is called if
validate is set to 'true' in the Action definition in
the struts-config.xml.  Or you can call the validate
method yourself from an Action if you need to.

Re: Automatic form validation

[David Winterfeldt]

You should have access to the bean if automatic
validation fails.  Are you seeing any error messages
even?  I would double check your struts-config.xml and
your html:form tags reference to the action.

Re: DynaValidatorActionForm

[David Winterfeldt]

I don't see anything wrong, but I wrote the javadoc so
I might be missing something.

DynaValidatorForm - uses the name of your form bean
(registrationForm) to retrieve the set of validation
rules

DynaValidatorActionForm - uses the name of your action
(/registration) to retrieve the set of validation
rules

These just give you a choice how you want to handle
storing/retrieving your validation rules.

The form element's name attribute in the
validation.xml is just a key used to store and
retrieve a set of validation rules.

Re: Struts Validator: Use of anchor tag

[David Winterfeldt]

I think there is an issue with using single quotes
inside error messages and variables in JavaScript.  Or
it might have been just variables.  You should
definitely be able to escape a double quote though if
you have any problems with the single quote.

Re: Validating an ActionForm "conditionnally"

[David Winterfeldt]

If you have a form nested like this, it probably
doesn't have the servlet reference set on it.

ServletContext application =
getServlet().getServletContext();

Otherwise what you are doing should be fine.

RE: How can I used html:select with a Collection of String

[David Winterfeldt]

I normally use List (List myList = new ArrayList();)
or Collection.  If you are going to use Vector, at
least use it through the Collection or List interface
(List myList = new Vector();).  Although I wouldn't
use it unless you really need the synchronization.

Re: turning off debug on console - Validator

[David Winterfeldt]

The jars should match the same nights nightly build. 
I just moved the Struts Validator into the core a
couple nights ago (struts-validator.jar unecessary). 
So if you are able to use the nightly binary, it will
have all the jars you need in the lib directory. 
There are some changes to configuring the Validator. 
It is using the new PlugIn interface so you don't need
the ValidatorServlet defined in the web.xml anymore. 
I need to add new documentation and some of the
package names have changed.  You can look at the
Validator webapp for an example if you decide to do
this or post questions.

Re: turning off debug on console - Validator

I think the debug level wasn't getting passed to every
class, but everything was upgraded to use Commons
Logging a few weeks ago which will give finer control
over logging.  So if you download a recent nightly
build, this should be fixed.

Re: Validator Problem

[David Winterfeldt]

These tags were deprecated for a while and when the
Validator was repackaged under
org.apache.struts.validator they weren't moved over
since there are the equivalent tags in Struts.  So
they might not be there depending on what version of
the Validator you are using.

validator:errorsExist --> logic:messagesExist
validator:errors --> html:messages

If you download a release before the last one
(1/14/2002), the tags are still there.

Re: Struts Validator changing the "key" in the validator.xml

There are some examples here.

  mask
  ^[a-zA-Z]*$
   
 

or you can override the default message:

 

   

   
  mask
  ^[a-zA-Z]*$

Re: Struts Validator NoClassDefFoundError

[David Winterfeldt]

What version of the Struts Validator are you using? 
Package names were changed at some point from
com.wintecinc.struts.* to
org.apache.struts.validator.* (1/14/2002).  When this
was done, most of the validator was moved to the
Jakarta Commons Validator
(http://jakarta.apache.org/commons).  I would double
check the files/package names in the jar you have.

Re: indexing of errors?

[David Winterfeldt]

Your property isn't really 'blah'.  It is 'blah[0]',
'blah[1]', etc.  So if you use the full property for a
field for the ActionErrors key, then you can retrieve
it next to each field.

ActionErrors errors = new ActionErrors();
errors.add("blah[0]", new ActionError("error.msg"));

 

This type of question would be a good question to ask
on the Struts User list.  And any development
suggestions are good to post to bugzilla if there
really is a feature request you want so they don't get
lost.

Re: Logging & Log4J in 1.1

Log4J recently added some new classes.  I would check
that you have a version of Log4J and Commons Logging
from the same time.  I had some trouble too until I
went and downloaded the latest version of each.

Re: Wanted : a perfect solution for CharterEncoding

[David Winterfeldt]

If you are using a servlet 2.3 compliant server like
Tomcat 4.0, you can use a filter to control this. 
Look at this example 'Example: Modifying the Request
Character Encoding' at: 

http://java.sun.com/products/servlet/Filters.html

Or you could modify the Struts source code to set your
character type on the request as it comes into the
ActionServlet if you can't use filters.  Although the
filter solution is much cleaner and separate from your
main code.

RE: Struts Validator Questions

[David Winterfeldt]

Could I see your xml for the validator definition?  Do
you have the depends in the xml validator set to
something so it is never getting to this validation? 
If you put debug code in the method, you never see it
run either?

The "select-one" is the correct type in Javascript for
an html:select tag.  I'm not sure what is in your
select list, but if it is an integer how can you check
that it is blank (zero length string) or null?  You
could use the range method to see if it falls in a
range or write your own.

No error messages?  Everything works on the same
principle.  Does the validator definition in the xml
have the same method and class defined as where the
validation method actually is (no types)?

You can make a Javascript method to match if you want
to.  You can follow one of the examples to see how to
make a generic Javascript method.  You have access to
the error message and the variables you've defined in
the Javascript.

You can do things like this in the Struts Validator
framework.  It is in the nightly source in the
contrib/validator directories and posted at
http://home.earthlink.net/~dwinterfeldt.;

This is a partial code snippet that uses a regular
expression to check if any of these characters are in
the field you are checking.  The regular expresion and
the error message are created based on the 'chars'
constant.  The double quote is escaped because this
information is stored in xml.  The '^' means all the
following are not allowed in the regular expression
(mask variable).  The 'msg name="mask"' overrides the
default error message for the mask validator.  The
'arg0 name="mask"' takes precedence over the arg0
element without a name attribute for the mask
validator.  This is a bit to get into, but it will do
what you want.

partial snippet from xml configuration file:

 
  
 
   
  
  
  
  
mask
[^${chars}]
  
   
 


ApplicationResources.properties:
my.errors.invalid={0} is not allowed in this field.

You can use logic:messagesPresent in the Struts
nightly builds to control formatting.


   
   
   
  
   
   


or to check if there is an error for a specific field:

Re: Vaildation using regexp fails for large strings

[David Winterfeldt]

I've had problems with this too.  That is why I added
minlength and maxlength validation routines so regular
expression wouldn't need to be used this way.

ORO could also be used if you write your own validator
using ORO instead of Jakarta Regexp.

Re: Question on Validation

[David Winterfeldt]

This isn't an issue with validating.  This is
formatting your view based on the ActionErrors object
generated by validation.

Struts nightly builds has logic:messagesPresent and
logic:messagesNotPresent jsp tags to control
formating.

The Struts Validator before the 1/14/2002 build posted
on 
http://home.earthlink.net/~dwinterfeldt have a
validator:messagesExist jsp tag.  Below are a couple
of examples.  The 'validator:messagesExist
property="lastName"' will evaluate the its body if
there is an error for the lastName property.

Messages Exist Tag
A simple logic tag that checks for an object in the
request attribute under the default or specified
message key. If there is an object, then the body of
the tag is evaluated.

Re: Logging in beans

[David Winterfeldt]

You could use this class.  It takes the ServletContext
as a constructor and extends PrintWriter.

org.apache.struts.util.ServletContextWriter

But I think using Commons Logging with Log4J is nicer.
 You can define that certain packages are logged to
different loggers in the Log4J configuration file. 
This example would log the package 'org.apache.struts'
to MyAppender.  You can setup as many of these as you
need.  You could have a master one and one for each
main package.  You can also control the log level for
each appender.

log4j.appender.MyAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.MyAppender.File=../log/my.log
log4j.appender.MyAppender.DatePattern='.'-MM-dd
log4j.appender.MyAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.MyAppender.layout.ConversionPattern=%d{MM/dd/
HH:mm:ss} %-5p %c - %m%n
log4j.category.org.apache.struts=DEBUG, MyAppender

RE: Logging in beans

[David Winterfeldt]

I think it is nice to use Commons Logging just so you
have the option of easily switching to another logging
framework.  You may want to use some other logging
framework other than Log4J (my choice) or Jdk1.4 at
some point.  You won't have to change any of you code
if you use Commons Logging.  Struts 1.1 is going to
use Commons Logging.  The Struts shared source is
using it as of last nights build.

RE: Logging in beans

[David Winterfeldt]

I would suggest using the Commons Logging Package
(http://jakarta.apache.org/commons/logging.html). 
This is a generic interface to logging packages.  If
Log4J is detected, it will use it.  

excerpt from the website:
"The Logging package is an ultra-thin bridge between
different logging libraries. Commons components may
use the Logging API to remove compile-time and
run-time dependencies on any particular logging
package, and contributors may write Log
implementations for the library of their choice."

Re: Struts Validator help

[David Winterfeldt]

It is keyed on the property, not the message resource
key.  So it would be the same as the property for you
html:text tag.



This would represent getEmail/setEmail.

Re: commons valiador

[David Winterfeldt]

The Struts Validator is in the contrib/validator
directory.

contrib/validator/src/share/org/apache/struts/validator/action/ValidatorForm.java

A binary version is available on my website and is in
the dist directory of the download
(dist/struts-validator.jar).

http://home.earthlink.net/~dwinterfeldt/

The Commons Validator just has the basic validation
framework for validating a java bean.  All Struts
specific things are still in the Struts Validator
project (contrib/validator).

There is an example in the nightly source in
contrib/validator (contrib/validator/src/example and
contrib/validator/web/example).  It is also posted at

a compiled jar of the Commons Validator in the build

Re: Validation Question?

[David Winterfeldt]

The issue is associating error messages, error message
arguments, and validation information like masks,
dates, etc. for different locales.  Also it would
start getting messy having regexp expression and other
things all directly associtaed with the custom jsp
tags.  Also, to store this information in the jsp page
would start cluttering your view with business logic.

There are a few other validation frameworks that
people have written.  They are posted here if you want
to look at them.

Re: Why ActionMessages not part of Struts 1.0.1?

[David Winterfeldt]

Only bug fixes have gone into Struts 1.0.1.  Adding
the ActionMessages would be a feature.  Plans are in
the works for having a Struts 1.1 release which would
be based off the nightly builds (no date set yet, but
should happen relatively soon).

RE: Where is the messages tag...

[David Winterfeldt]

The html:messages tag is in the nightly builds (not
v1.0).  It is very similiar to ActionErrors, but can
be used for general messages.

ActionMessages messages = new ActionMessages();
messages.add(ActionMessages.GLOBAL_MESSAGE, new
ActionMessage("userForm.insert", info.getUserName()));
messages.add("activationDate", new
ActionMessage("userForm.active",
info.getSubscriptionLength()));


  
 
  


By default the tag will retrieve the request scope
bean it will iterate over from the Action.ERROR_KEY
constant string, but if this attribute is set to
'true' the request scope bean will be retrieved from
the Action.MESSAGE_KEY constant string. Also if this
is set to 'true', any value assigned to the name
attribute will be ignored.

Re: Returns from erroneous validation without aditional information

[David Winterfeldt]

When I want to do something like this, I set
validation="false" in the struts-config.xml for the
action.  Then I can call validate on the ActionForm
when appropriate.  Or you can have two actions.  One
to prepopulate fields (with validation="false") and
one with validation="true".

Re: changing default text.

[David Winterfeldt]

If you are using the nightly builds, there are
html:messages, logic:messagesPresent, and
logic:messageNotPresent to help with formatting and
display of messages.  The html:messages tag is like
html:error, but it iterates through the errors
instead.  Specifying a header and/or footer by passing
in the message resource key is optional.

Re: Form Date Validation - how to?

[David Winterfeldt]

There is a validation framework in the
contrib/validator directory in the nightly source.  It
can handle date valdiations.  


 
 
   datePatternStrict
   MM/dd/
 


So if you keep your field in the ActionForm a String,
you could use one of the transformation packages to
transform the data from the ActionForm to a JavaBean
with the correct types for fields and then continue
processing your business logic.  Of course this may be
more than you want to get into if you just have the
date field and everything else doesn't need to be
transformed.

Struts Transformer by Ron Smith
http://www.rpsenterprises.com/struts/index.html

Mapper Framework by Capco
http://www.rpsenterprises.com/struts/index.html

Hope this helps.

Re: org.apache.struts.action.MESSAGE

[David Winterfeldt]

This is the value of Action.MESSAGES_KEY.  It is used
to store the application message resources
(ApplicationResources.properties) under application
scope.

Action.MESSAGES_KEY =
"org.apache.struts.action.MESSAGE"

I don't know why you would get intermittent messages. 
It should load at startup and then stay cached.  You
can check that you are correctly referencing your
properties file in the web.xml.

Re: PLEASE: Validating A session level form on the Server side

[David Winterfeldt]

The validator example also is doing the validations
server side.

Multi Page Forms
The field element has an optional page attribute. It
can be set to an integer. All validation for the any
field page value less than or equal to the current
page is performed server side. All validation for the
any field page equal to the current page is generated
for the client side Javascript. A mutli-part form
expects the page attribute to be set.
   ex:  

This could be used instead of page numbers if you
define a separate action for each validation.
ValidatorActionForm
This class extends ValidatorForm and provides basic
field validation based on an XML file.  The key passed
into the validator is the action element's 'path'
attribute from the struts-config.xml which should
match the form element's name attribute in the
validation.xml.

It's ok to ask.  Do you have the ValidatorServlet

That's true.  I was thinking that if you have some
inner value objects that you are accidentally setting
to null in the reset instead of reinitializing or
clearing that could cause a problem.

I see you forwarding to this after an error, but I
don;t see the forward defined.
   return (mapping.findForward("user1add"));

Maybe there is an issue with the reset method in your
ActionForm?  The validation error messages make sense?
 If they do then the data is being populated correctly
into your ActionForm from you form.

I assume you mean the validator framework
(contrib/validator).  It doesn't use ActionMessage
from Struts.  The issues with using the newer version
of the Validator with Struts 1.0 are that the
Validator uses the commons packages for Bean Utils,
Collections, and the Digester.  I believe some people
have this working, but I haven't had time to try it.

If you can use a servlet engine that supports v2.3
(tomcat 4.0), you could use a Filter to parse out the
url that was entered and extract any parameters that
you encoded differently.  Then you could forward the
request to the actual page or servlet it should go to.

Re: Struts Validator (dumb?) question

[David Winterfeldt]

You either would need to define at least one action
with validate="true" and another with validate="false"
or perform the call to the ActionForm validates method
yourself in the action.  There is an example of using
one action this way in the jdbc example web app that
comes with the Validator.

ActionErrors errors = form.validate(mapping, request);

if (errors == null || errors.empty()) {
   update(request, info);
} else {
   saveErrors(request, errors);
   return (new ActionForward(mapping.getInput()));  
}

RE: ActionError Header/Foorters - can Global vs Non-Global be dif ferentiated

[David Winterfeldt]

I'm not 100% sure if this is what you are asking
about, but the Validator Framework has the concept of
levels of validation errors.  You can setup a
validator to depends on another one.  The 'minlength'
validator depends on the 'required' validator.  So
until this level (required) is completed, the next
level will not occur.






You can find the framework in the Struts nightly
builds in the contrib/validator directory or at the
url below.

The equivalent of validator:errors is now 
html:messages in the Struts nightly builds.  The
equivalent of validator:errorsExist is now 
logic:messagesPresent in the Struts nightly builds.  I
consider the most recent releases of the Validator to
be in sync with the nightly builds.  If you look at
the revision info
(http://home.earthlink.net/~dwinterfeldt/revision.html),
you can see what Validator version was built/developed
with what version of Struts.

RE: Automation options between ActionForm and Value Object?

[David Winterfeldt]

Here are two code generators that are out there if you
haven't seen them already (listed on
http://www.husted.com/struts/resources.htm).  Ravi has
worked on his a lot more than I have.

Struts CodeMaker by Ravindran Ramaiah
Generate Struts application by reading configuration
file or JSP files.
http://www.husted.com/struts/resources/codemaker.htm

Struts Generator by David Winterfeldt
Based on the generator.xml and a table/query an xml
file is generated. Based on the generated xml file a
primary key class, data bean class, jdbc class, and an
ActionForm (Struts) can be generated.

Re: and struts:erros>

[David Winterfeldt]

You can still use the ones from the validator package
if you need to, but if you are using more recent
nightly builds all the functionality for the
deprecated validator tags have been moved to struts.

html:messages logic:messagesPresent, and
logic:messagesNotPresent

Re: David Winterfeldt's Validator Framework + Jbuilder 5.0 + Tomcat 3.2.1

[David Winterfeldt]

I wasn't using JBuilder, but I did have problems with
Tomcat 3.2.1 and Struts/Validator.  There were class
loading issues.  Even if you take out the validator, I
don't think you can get Struts running.  Is there any
way to upgrade to a newer version of Tomcat?  Sorry
this isn't more helpful to you problem, but I though I
would at least share what I know.  I'm currently using
Tomcat 4.0 with the nightly builds.

Re: JSP used to convert xml to html applying XSL

[David Winterfeldt]

There is a nice tag library you can use for
transformations.

http://jakarta.apache.org/taglibs/doc/xsl-doc/intro.html

Excerpt from Apply.jsp from the xsl-examples.war:
This version of the table was created by loading
the nested content with
an  action (simulating
asking a different
servlet or JSP page to render the desired XML data)
and using the same
external XSL stylesheet.

Re:

You have validate="true" in your action?  Or in your
Action if you are definitely getting back an
ActionErrors object with messages then you could use
the saveErrors method in the Action class to save it. 
Also, do you have errors.header and errors.footer
defined?  There is also an html:messages that tag
iterates through error messages if you are using a
recent nightly build.

Re: Struts-Validator problem: NoClassDefFoundError

[David Winterfeldt]

The ActionMessage class is in the more recent nightly
builds of Struts.  Are you using html:messages?  This
uses that class.  I'm not what else would be looking
for this in a JSP page though.  The validator tags
shouldn't be making a reference to this class.  

To check if the ValidatorResources are loading you can
see something print to the console window if the debug
for the ValidatorServlet is set to greater than 1.  I
would try to get the server side validation working
before testing the client side.  Once the server side
is working, the client side validation shouldn't be a
problem.

Re: Struts Validation question

[David Winterfeldt]

It doesn't skip it just like if you define an
html:text on your JSP and the field doesn't exist it
causes an exception.  I don't think it stops
validating though since all exceptions are caught.

Re: Messages like Errors...

[David Winterfeldt]

Are you talking about a general message or an error
message?  The below works with nightly builds or the
Validator project (in the Struts nightly source
contrib/validator directory or
http://home.earthlink.net/~dwinterfeldt) has tags to
do this if you aren't using nightly builds.


   
  
 
  
   


or

ActionMessages messages = new ActionMessages();
messages.add(ActionMessages.GLOBAL_MESSAGE, new
ActionMessage("save.msg"));
saveMessages(request, messages);

Re: Validator Nightly builds and Struts 1.0

[David Winterfeldt]

The first error sounds like a class loading issue. 
I'm using Tomcat 4.0, but I saw something like this on
Tomcat 3.2.1 for the latest Struts and Validator
builds.  Maybe someone else will comment about that.

The latest source of the Validator is using some
Struts tags that are in the nightly build so the
example won't run with Struts 1.0 without
modifications.

I don't know when Struts 1.1 will go final so it is
hard to say what features will be added between now
and then.

The revision notes cover most things.  I'm aware of at
least one person running a nightly build release of
the Validator with Struts 1.0.  The commons packages
(beans, collections, digester) are being used so they
would need to be added.  Otherwise a nightly build of
the Validator should work OK with Struts 1.0, but I
haven't tested this.

This shouldn't be required.  You don't need to add
this javascript.  It just gives you a way to turn off
the javascript validations for the cancel button (or
any other button you don't want validation run on).

The revision list covers most changes.  The new min
and max length validators could be cut and paste into
the 7/2/2001 release.  I'm thinking about making a few
updates (min/max and any bug fixes) to the 7/2/2001
release and making it a version 1.0 release.

I don't remember if you can still use this format or
not, but you should really use the nested element
structure.  This was changed so you could use cdata
tags around a regular expression and not have to
escape anything out.

I've looked at Castor and it seems nice.  I didn't end

generate ActionForms.

You can have nested properties if you aren't aware of
that.  So for a property you could have "address.name"
and this would be the equivalent of
getAddress().getName().  ("address[2].name" ->
retrieve object from array and then call getName()) 
So this can let you have different beans nested inside
each other.

Dave Hays has added the functionality of indexed
functionality for tags.  This lets you reference
anything the logic:iterator tag can loop through and
generate the correct indexed property name
dynamically.  It is in the nightly builds or you can
download it here. 
http://www.husted.com/struts/resources/indexed-tags.htm




   



public List getListElementList();
public Object getListElement(int index);
public void setListElement(int index, Object value);

RE: Questions About Struts Validator

[David Winterfeldt]

The validator is in the Struts nightly source
downloads in the contrib/validator directory.  I also
keep the documentation and some downloads posted at
this url.  The most current will always be in the
nightly downloads.

http://home.earthlink.net/~dwinterfeldt/

The most recent release has the min/max length
validations.  The 7/2/2001 release was the last one
made with Struts v1.0.  It doesn't have the min/max
length, but you can make a 'mask2' validator (as you
can in most releases).

Unless you have a checkbox on your form and you have
validation.  Then in the case that a checkbox that was
checked and the page fails validation. The user is
then returned to the form to fix their input and
unchecks the checkbox.  Nothing will be submitted for
the checkbox (this is an html form issue) so the
property with your checkbox will still be checked.  So
any checkbox fields need to be in the reset method
(other fields don't have to be).

RE: Questions About Struts Validator

[David Winterfeldt]

What feature are you referring to?  the min/max
validators or defining a second mask validator as
'mask2'?  Also, this would depend on the validator
version you are using.  Are you asking if the latest
release will work with Struts 1.0?  It should. 
Someone said they were using a more current release of
the validator with the Struts 1.0 release.  It uses
the commons packages (bean, digester, and collections)
though so you would need to add them to your
WEB-INF/lib directory.

RE: Questions About Struts Validator

[David Winterfeldt]

That isn't possible with the default mask validator. 
I've recently added a min and max length validation to
nightly builds though.  Or you could either write your
own mask validation method that accepts multiple
inputs or you can define the mask validator again
under a different name like mask2.




 
 
 
 
 
 
   mask
   ^[a-z]*$
 
 
   mask2
   ^[A-Z]*$
 
 
   maxlength
   16

Re: DB Connection Pooling

[David Winterfeldt]

Thanks.  This looks nice, but I'll probably just stick
with the Struts one for now since the connection can
refresh and I have a lot of other things to do on my
project.

Sorry.  Never mind.  I just saw that there was support
added for refreshing the built in Struts Connection
Pool, but I didn't know about it.  You can add on of
these lines in a data-source element.

DB Connection Pooling

[David Winterfeldt]

What would someone recommend for using as a connection
pool besides the Struts one?  Basically I'm looking
for a similiar product, but I want it to be able to
check if a connection has been lost or gone bad and
create a new one to replace the bad one.  I see that
there is a pool project in jakarta-commons, but it
doesn't seem like it is ready yet for production use.

Re: html:errors

[David Winterfeldt]

I thought I would send this modified from what
Jonathan sent so it was clear how to add an error. 
The first parameter adding an error to ActionErrors is
the key it is filed under.  So typically you use the
property name of the field so it can be retrieved next
to the field if you need to.

ActionErrors errors = new ActionErrors();
errors.add(ActionErrors.GLOBAL_ERROR,
   new
ActionError("error.password.mismatch"));
errors.add("username",
   new ActionError("error.username"));

IN YOUR RESULTING JSP PAGE


Or if you are using a recent nightly build you can
iterate through your error messages helping to keep
html out of your message resources.

Re: where should validation happen?

[David Winterfeldt]

I wanted to mention that the Validator validation
framework has some basic validations that tie
Javascript to the server side validations together. 
So you don't have to worry about the Javascript being
run because the server side validation will always
happen.  The validation framework is in the
contrib/validator directory of the nightly source and
it is also posted here:

Re: bean:message with bean

[David Winterfeldt]

If they are message keys from the resource file, like
msg.hello=Hello, then it should be key not name.


  



The tag bean:write uses the name attribute (as do most
other tags in one way or another).
