Subject: Struts Validator and Select boxes
Hi,
I am using Struts validator.
One page of mine has dates displayed as MM DD .
All the above 3 are displayed in seprate combo/select boxes.
I need to do some custom validations on these fields.
I wrote a custom class for the same
Looks like -
public static boolean validateDates(Object bean,
ValidatorAction validatorAction,
Field field, ActionErrors errors,
HttpServletRequest request)
{
String actionType = ValidatorUtil.getValueAsString(bean,
field.getVarValue(actionType)); // A hidden form field
String fromMonth = ValidatorUtil.getValueAsString(bean,
field.getProperty());
String fromDay = ValidatorUtil.getValueAsString(bean,
field.getVarValue(fromDay));
String fromYear = ValidatorUtil.getValueAsString(bean,
field.getVarValue(fromYear));
String toMonth = ValidatorUtil.getValueAsString(bean,
field.getVarValue(toMonth));
String toDay = ValidatorUtil.getValueAsString(bean,
field.getVarValue(toDay));
String toYear = ValidatorUtil.getValueAsString(bean,
field.getVarValue(toYear));
System.out.println(actionType + actionType);
System.out.println(fromMonth + fromMonth);
System.out.println(fromDay + fromDay);
System.out.println(fromYear + fromYear);
System.out.println(toMonth + toMonth);
System.out.println(toDay + toDay);
System.out.println(toYear + toYear);
return true;
}
O/P of the above code -
actionType searchPage
fromMonth 2
fromDay null
fromYear null
toMonth null
toDay null
toYear null
It also gives me No Name Specified error.
Point to note is that the all other fields other than 'actionType' are select boxes.
It gives a null for all the field types that are of html:select.
Is this a known BUG or am i going wrong somewhere ?

RE: Handling Date objects in ActionForm gracefully
As someone with good experience in MVC-based applications but a newbie
to Struts, what I understand from this discussion is that the
recommended implementation would have to comply, at least, with this
guidelines:
- The conversion code is encapsulated in a separate class (I suppose one
converter class per each String, Target Data Type combination
required, right?).
- Passes all (String) parameters to a Business Object that encapsulates
the use case (I mean, the logic) and, from within that BO, use the
corresponding converter classes for getting the actual data object to
flow around (i.e. be eventually get-ed or set-ed from the DAOs/DTOs, bla
bla bla...)
I'm I right here or am I missing any other IMPORTANT aspect(s)?
STILL, there is something I don't get: how would you implement /
encapsulate then the opposite direction for data conversion; in other
words:
- Convert from original data types towards String (another method in
the same converter class?)
- Map (set) some (non-String) data object into the corresponding String
property on the form bean.
Thanks,
Freddy.

Asunto: Re: Handling Date objects in ActionForm gracefully
You deal with the conversion else where but not in the form bean, you
can argue about it or just believe me. The action form sits between the
view and the action, the date conversion goes on between the action and
the model.
Your approach isn't that bad its just not to the MVC pattern that
struts follows (not that its the only one).
Create a date convertion util class or something.
If you dont want to take my word for it here's what craig had to say
albeit in response to a different question
snippet
As the original designer of Struts :-), I must point out that the
design of
ActionForm (and the recommendation that form bean properties be
Strings) is
***very*** deliberate. The reason this is needed is obvious when you
consider
the following use case:
* You have an input form that, say, accepts only integers.
* Your form bean property is of type int.
* The user types 1b3 instead of 123, by accident.
* Based on experience with any garden variety GUI application,
the user will expect that they receive an error message,
plus a redisplay of the form ***WITH THE INCORRECT VALUES
THAT WERE ENTERED DISPLAYED SO THE USER CAN CORRECT THEM***.
* The current Struts environment will throw an exception
due to the conversion failure.
* The suggested solution will ***hopelessly*** confuse the
nature of a form bean, which is part of the VIEW tier, with
model beans that have native data types.
Struts does not include any sort of user interface component model
where the
details of conversion are hidden inside the user interface component.
If that
is what you are after, you should look at a *real* user interface
component
model (such as using JavaServer Faces with a Struts application).
Corrupting
the functionality of a form bean to *pretend* that it is a user
interface
component is only going to create complications for the world.
/snippet
I hope this helps

public DataObject{

}
My Action form is:
public MyActionForm extends ActionForm{
public DataObject getDataObject();
public void setDataObject(DataObject dataObject);
}
My jsp contains
html:text property=dataObject.asOfDate/
This will fail if the user does not enter any date. I want the
(changed) struts framework to handle that.
I did not want to create a new method with type String for every Date
field
Hope this explanation helps !!

HttpUnit is also a neat tool which might help. Have a JSP generate the
HTML and access that using HttpUnit (or a simple URLConnection/Socket
for that matter). And you can get the generated HTML in your Action.

A cleaner approach would be to use Custom Tags to have the HTML

JSPs are not sent to the browser, it is the code they generate that is

Or maybe I dont understand your requirements.

Re: Handling Date objects in ActionForm gracefully
I think the way of going about converting is pretty open, either have
some conversion utils between the web tier and the model. I tend to do
it in the action and then when things get long or i need the code again
move it out into a util class or like you're saying make my model util
classes deal with strings (this makes a lot of sense as then other
front ends can be plugged on).
Talk of MVC aside (after all MVC is a broader issue than the particular
pattern that struts is based on) why piss about dealing with all sorts
of errors and exceptions being thrown in the place where its hardest to
deal with them?
You can and people do use different types for form beans, but I just
don't see the point. Date comes up often and lets face it dates are
more user friendly as dropdown menus rather than free text, so
getDay() , getMonth() and getYear() IMO are a simpler way of going
about things. Then have methods in you model that create a date based
on that, or have a util class in the web tier as you can deal with
validating the three values. Perhaps even have a date that's in you
form bean but is set and got (passed participle of get) via string
flavors day, month and year.
Not sure if this works but I think the idea is valid (corrections
welcome).
public class SomeForm extends ActionForm {
private Calendar aDate = Calender.instance();
public String getDay() {
int d = aDate.get(Calendar. DAY_OF_MONTH);
return Integer.toString(d);
}
public void setDay(String day) {
aDate.set(Calendar.DAY_OF_MONTH,Integer.parseInt(day));
}
...
protected Date getAdate() {
return dDate.getTime();
}
}
This way come checking and comparing values before can be done, before
passing anything up to you model. Many folk would say that this should
be done in the model, but i'd say situations where you need to check if
a user has entered a valid date (e.g. expire and from dates with a
credit card).
This functionality will want to be produced even if you change the
model , if you wanted to demo your web tier on its own (without a model
e.g acme ltd credit card form) and therefore doing it ONLY in the
model would be limited.
Very much IMO and I'm not MVC guru, but that's my understanding.

RE: Handling Date objects in ActionForm gracefully
Since I just wrestled greatly with this particular beast, my $.02 follows.
Subclass whatever flavor of ActionForm you use, and give it a method with a
footprint like-
java.util.Date StringToDate(String)
{
}
This way you can do something like this in your action:
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception
{
Myform mf = (Myform) form;
BizObject bo = new BizObject();
String dateText = mf.getDateString();
bo.setDate(mf.StringToDate(dateText);
// etc
}
This works very well unless internationalizing your app because the converter
needs a DateFormat defined to read the String correctly. And I am, so I need
to come up with something.
I don't suppose there is a version of BeanUtils that lets the user pass a
DateFormat into copyProperties :-)???

How does ActionForm data pass through container called form based login page?
Hi, Suppose I've got a web based form that posts data to an action, and I have that action protected by container form based authorization - how does the ActionForm data get through. I have a situation like this, and my ActionForm is empty after I've been through the form-based login page. One could say - stick the input form in the constrained area also, so the login page doesn't come between the input form and the action that processes it - but this is actually occurring when a session times out whilst sitting at the input form.

This way come checking and comparing values before can be done, before
passing anything up to you model. Many folk would say that this should
be done in the model, but i'd say situations where you need to check if
a user has entered a valid date (e.g. expire and from dates with a
credit card).
This functionality will want to be produced even if you change the
model , if you wanted to demo your web tier on its own (without a model
e.g acme ltd credit card form) and therefore doing it ONLY in the
model would be limited.
Very much IMO and I'm not MVC guru, but that's my understanding.

Asunto: Re: Handling Date objects in ActionForm gracefully
You deal with the conversion else where but not in the form bean, you
can argue about it or just believe me. The action form sits between
the
view and the action, the date conversion goes on between the action
and
the model.
Your approach isn't that bad its just not to the MVC pattern that
struts follows (not that its the only one).
Create a date convertion util class or something.
If you dont want to take my word for it here's what craig had to say
albeit in response to a different question
snippet
As the original designer of Struts :-), I must point out that the
design of
ActionForm (and the recommendation that form bean properties be
Strings) is
***very*** deliberate. The reason this is needed is obvious when you
consider
the following use case:

Re: Handling Date objects in ActionForm gracefully
Freddy. No, you misunderstood if you thought I was responding with any
hostility whatsoever.
There is a general problem where input would be better validated in the
web tier so it can be decoupled from the model. So times comparing two
dates would be useful and so on. But i think its also try to say that
using anything but strings for user input will lead to problems.
And my suggestion could well be incorrect, I was putting it out there
to see what response it would provoke.

Asunto: Re: Handling Date objects in ActionForm gracefully
I think the way of going about converting is pretty open, either have
some conversion utils between the web tier and the model. I tend to do
it in the action and then when things get long or i need the code again
move it out into a util class or like you're saying make my model util
classes deal with strings (this makes a lot of sense as then other
front ends can be plugged on).
Talk of MVC aside (after all MVC is a broader issue than the particular
pattern that struts is based on) why piss about dealing with all sorts
of errors and exceptions being thrown in the place where its hardest to
deal with them?
You can and people do use different types for form beans, but I just
don't see the point. Date comes up often and lets face it dates are
more user friendly as dropdown menus rather than free text, so
getDay() , getMonth() and getYear() IMO are a simpler way of going
about things. Then have methods in you model that create a date based
on that, or have a util class in the web tier as you can deal with
validating the three values. Perhaps even have a date that's in you
form bean but is set and got (passed participle of get) via string
flavors day, month and year.
Not sure if this works but I think the idea is valid (corrections
welcome).
public class SomeForm extends ActionForm {
private Calendar aDate = Calender.instance();
public String getDay() {
int d = aDate.get(Calendar. DAY_OF_MONTH);

You need to understand that it is primarily intended to provide the common logging API (the simple logger is included just to get you started) and then you configure it to use whatever logging facility under the covers that you want to. Most people use log4j, but, you could also use the native logging support in JDK 1.4 or greater. I recommend configuring to use log4j. I also recommend taking the time to read the short intro manual to log4j found here: http://tinyurl.com/3hlrq I recently posted the contents of a simple log4j configuration file that does have an example of the necessary configuration to write log messages both to the console and to file. Check the list archives for a recent post on logging by me. I use this setup with Tomcat and Weblogic. The one configuration difference I found is that Weblogic doesn't like relative file paths for location of log files and Tomcat handles that just fine. Good luck, Van Mike Van Riper Silicon Valley Struts User Group http://www.baychi.org/bof/struts/ P.S. You can either remove the commons logging properties file or explicitly configure it to use log4j. As long as you setup log4j properly in your runtime environment, the commons logging logic will use it by default unless you have a commons logging properties file that explicitly specifies a different logger implementation.

Hi, I have to use: WebSphere Studio Application Developer (Windows) Version: 5.1.0 I developed my app with the StrutsStudio, as it is not that complex. But know I have to run it on WSAD and run into different problems: a. WSAD did not like the validation.XML (so deleted it cause I did not use it anyway) b. I use iBatis for the DB stuff and iBatis needs a newer JDOM version. (so I integrated that and the coresponding DTDs for iBatis, as I was not able to referenc it from the net) so far everything seams to work, but know I got some straing error messages, that i did not define my ibatis xml files correctly?!? But the same app works fine on a Tomcat-Server! I read in Hubert Rabago mail: Just as I suspected. I'm forced to use WSAD where I work, and I've turned off a whole bunch of validations by it, including Struts. It complains of a lot of things that either it doesn't know about or it's just plain wrong about. Fortunately, I only have to run the app there, and not have to do any serious coding with it. My teammates aren't as fortunate, though. And thought that this could be a way to solve my problem, but did not find the right spot to enabel the validation.

I'm assuming that the container is intercepting before Struts ever gets a chance to create an ActionForm based on the submission, so I don't think that making them session scoped is likely to help. This probably doesn't constitute a solution, but perhaps extending the session timeout would help a bit. Perhaps you could come up with some kind of javascript hack which calls a URL against the struts app periodically to keep the session alive?

The second one writes logs to a file [file path]. This file should also go under WEB-INF/classes Roy. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Perhaps you could come up with some kind of javascript hack which calls a URL against the struts app periodically to keep the session alive?

Hi,
Suppose I've got a web based form that posts data to an action, and I
have that action protected by container form based authorization - how
does the ActionForm data get through.
I have a situation like this, and my ActionForm is empty after I've been
through the form-based login page.
One could say - stick the input form in the constrained area also, so
the login page doesn't come between the input form and the action that
processes it - but this is actually occurring when a session times out
whilst sitting at the input form.
Thanks

Re: Struts Validator and Select boxes
Posting whats in your validation.xml for the form and the bit of your jsp
with your select fields would be helpfull.
If you take the fromDay as an example, you are using
field.getVarValue(fromDay) - if you don't have a var defined in your
validation.xml for fromDay then that would cause the No Name Specified
error - same goes for fromYear, toMonth, toDay and toYear.
As for getting nulls, looks to me again that whats specified for the vars
in your validation.xml doesn't tie up with the names specified on your form.
From your code I would expect something like the following in your
validation.xml
form.
field
varvar-namefromDay/var-name
var-valueformFromDay/var-value
/var
varvar-namefromYear/var-name
var-valueformFromYear/var-value
/var
varvar-nametoMonth/var-name
var-valueformToMonth/var-value
/var
varvar-nametoDay/var-name
var-valueformToDay/var-value
/var
varvar-nametoYear/var-name
var-valueformToYear/var-value
/var
/field
/form
Do you have the properties in your form correct (i.e in this example
formFromDay, formFromYear, formToMonth, formToDay, formToYear).

Subject: Struts Validator and Select boxes
Hi,
I am using Struts validator.
One page of mine has dates displayed as MM DD .
All the above 3 are displayed in seprate combo/select boxes.
I need to do some custom validations on these fields.
I wrote a custom class for the same
Looks like -
public static boolean validateDates(Object bean,
ValidatorAction validatorAction,
Field field, ActionErrors errors,
HttpServletRequest request)
{
String actionType = ValidatorUtil.getValueAsString(bean,
field.getVarValue(actionType)); // A hidden form field
String fromMonth = ValidatorUtil.getValueAsString(bean,
field.getProperty());
String fromDay = ValidatorUtil.getValueAsString(bean,
field.getVarValue(fromDay));
String fromYear = ValidatorUtil.getValueAsString(bean,
field.getVarValue(fromYear));
String toMonth = ValidatorUtil.getValueAsString(bean,
field.getVarValue(toMonth));
String toDay = ValidatorUtil.getValueAsString(bean,
field.getVarValue(toDay));
String toYear = ValidatorUtil.getValueAsString(bean,
field.getVarValue(toYear));
System.out.println(actionType + actionType);
System.out.println(fromMonth + fromMonth);
System.out.println(fromDay + fromDay);
System.out.println(fromYear + fromYear);
System.out.println(toMonth + toMonth);
System.out.println(toDay + toDay);
System.out.println(toYear + toYear);
return true;
}
O/P of the above code -
actionType searchPage
fromMonth 2
fromDay null
fromYear null
toMonth null
toDay null
toYear null
It also gives me No Name Specified error.
Point to note is that the all other fields other than 'actionType' are
select boxes. It gives a null for all the field types that are of
html:select.
Is this a known BUG or am i going wrong somewhere ?

I have a situation like this,
[OT] JTA, JDBC and data persistence
Hello everybody, An off-topic question (it's Friday, I hope you accept it!): I want to implement a Business Object Model on top of many DAOs. Those BOs will be - obviously - related to each other (mainly 1:n and m:n relationships). I must implement this in such way that, when - for example - deleting a BO that has 3 children associated (therefore, those must be deleted as well), it's is possible to do so atomically.

Accessing Struts beans with keys defined in the Globals class
Hello everybody,
I hope it's not a trivial question.
I'm trying to access the current Locale from a JSP page. The key to
access the Locale is stored in variable
org.apache.struts.Globals.LOCALE_KEY. So what I did is to look up the
value of the variable in the source file org.apache.struts.Globals.java
and used that value in a JSP page like this:
${sessionScope['org.apache.struts.action.LOCALE']}
It works but I'm wondering if there's a more direct way, maybe using one
of the tags provided by the Struts framework, to access beans stored
under keys defined in Globals.java.
Thanks in advance for any help.

The Struts-EL is what I'd recommend, which supports exactly what you want to

option value=${accounts.number}${accounts.number}/option
Otherwise I _think_ I've done this nastiness and it worked, but I might have
been doing it with plain HTML (non-struts tags):

Re: [OT] JTA, JDBC and data persistence
Freddy, I think you only need to look into using JTA and XA transactions if you are spanning multiple data sources (databases).

These tools usually provide support for transactions, in addition to providing a mapping layer for your objects.

searchType should be saved as an attribute of (preferably) your request

Actually, you shouldn't need to specify a value here at all. The

You wouldn't, you'd set the property of the Form bean and let Struts
handle it.
If you need to pre-populate the form, you do that in the Action by
calling setSearchType() on your Form bean. Then when you forward to the
JSP, Struts will fill in the value.
Can you explain more about your situation? I'm making some assumptions
that may not be correct.
In general there's no need to touch the 'value' attribute of the tags
that render HTML form elements.

RE: Pls help me in configuring common logger
Sougata, I can point you in the right direction, but, I don't have time to spell everything out for you. I think you need to do some work on your own reading the commons logging docs. You need to understand the commons logging package and how to configure it to use log4j or the native logging facilities in JDK 1.4. When I mentioned the simple logger, I was referring to this implementation of org.apache.commons.logging.Log: org.apache.commons.logging.impl.SimpleLog If you are using the commons logging package, it has a properties file you can use to specify which Log interface implementation to use. I could be wrong, but, when this file is not provided my experience has been that it will automatically detect the presence of a properly configured log4j and instantiate a org.apache.commons.logging.impl.Log4JLogger. If a properly configured log4j is not detected, it will default back to the SimpleLog implementation.

You need to understand that it is primarily intended to provide the common logging API (the simple logger is included just to get you started) and then you configure it to use whatever logging facility under the covers that you want to. Most people use log4j, but, you could also use the native logging support in JDK 1.4 or greater. I recommend configuring to use log4j. I also recommend taking the time to read the short intro manual to log4j found here: http://tinyurl.com/3hlrq I recently posted the contents of a simple log4j configuration file that does have an example of the necessary configuration to write log messages both to the console and to file. Check the list archives for a recent post on logging by me. I use this setup with Tomcat and Weblogic. The one configuration difference I found is that Weblogic doesn't like relative file paths for location of log files and Tomcat handles that just fine. Good luck, Van Mike Van Riper Silicon Valley Struts User Group http://www.baychi.org/bof/struts/ P.S. You can either remove the commons logging properties file or explicitly configure it to use log4j. As long as you setup log4j properly in your runtime environment, the commons logging logic will use it by default unless you have a commons logging properties file that explicitly specifies a different logger implementation.

Larry, I'll go out on a limb here and say that since the response is being generated on the server by a servlet or JSP, there is no need for getHeader() or getHeaders() methods because the developer is setting them. The HttpServletResponse interface has addHeader() and addXXXHeader() methods to add headers to the response. There is also the containsHeader() method which returns a boolean. -Richard --- Zhang, Larry (L.)

RE: html:options where values have embedded quotes
It might not be sexy, but a fast solution would be to use something else instead of quotes e.g. ^ or | and then use a small Javascript replace function to write out the text correctly?

And Struts should be able to match that to an existing entry so it can properly set the selected value. Instead, it seems the options tag isn't escaping the quotes at all (changing them to quot;) and that if we manually do it ourselves, the selected item still isn't being set when the page is reloaded.

RE: newbie html-el question
Hi Wendy,
Thanks for responding! Someone showed me a way to do what I needed to do,
but the way I'm approaching the entire problem may be kludged:
The user can click
Search Attributes | Search Components | Search Templates
I've provided html:link's like these respectively:
doPrepareSearch.do?searchType=attribute |
doPrepareSearch.do?searchType=component |
doPrepareSearch.do?searchType=template
so when they user lands on my form, I want to prepopulate the search type
based on what they chose. If they submit a search with bad data, then I'd
want the SearchForm's (extends ActionForm) validate() method to send the
back to the search form, this time keeping their most recent entries to the
form field -- if they changed search type for example now it would be
different.
I am new to Struts and may not be getting a key concept of it's Best
Practices usage. Does it make sense what I've described? Thanks again!,
Jim

You wouldn't, you'd set the property of the Form bean and let Struts
handle it.
If you need to pre-populate the form, you do that in the Action by
calling setSearchType() on your Form bean. Then when you forward to the
JSP, Struts will fill in the value.
Can you explain more about your situation? I'm making some assumptions
that may not be correct.
In general there's no need to touch the 'value' attribute of the tags
that render HTML form elements.

RE: Populating a Listbox
I've come across this in a few difference manifestations and the best course of action I've come across is dependant on the number of variations. If you're only talking about a couple of hundred or less, use a javascript array to populate the second dropdown on the fly. If you're dealing with more than that [6,000 in my case :)] then you're better off using an onChange event handler on the first dropdown to submit the page back to itself and use the action to generate the 2nd one from the database.

put name=title value=encoderconfig /
put name=body value=LOCATION /
/definition
I think it must be a easy solution, using tile tags.
The way I presented to you is the cleaner one :)
If you define the put declaration in Tiles it will always be static (at
least for what I understood and read so far).
If you want to make a tiles attribute dynamic, you must specify and
implement the tiles controller (described in the other mail).
The not so clean solution is to use a tiles template with a c:import
url='${request.dynamicTilesAttribute}'/ inside.
what do you think?
I guess this is not a question of what I think... It is more of how it
works :)
This could be a nice feature to Tiles though.
One could implement a Tiles controller that made this possible. You just
needed to parse all of attributes for ${scope.Attribute} values = it would
be inneficient most of the attributes are static. If the put declaration had
a dynamic attribute (true/false) it would certainly much more
interesting/efficient. Maybe I will try and do this on my weekend ;)

expression language in custom tags? I think you can, but I am not quite
sure how to do it. Do you get this for free by just upgrading to a JSP 2.0

this behaviour. For example, I want to do my tag to get his behaviour:

RE: Help on struts
Thanks for your guidance. You are right , we are in the case where user will come back from search page. I will try as you suggested and give feedback. Regards Shoaib I guess the first thing to consider is what you mean by come back to the previous page. Do you just mean have the user redirected back to that url when they have finished playing with the search? or is it more complex. For example the previous page is a form, and they are halfway through filling it in when they need to search, and on completion need to take up where they left off with filling it in? In the first case the easiest way (Im assuming there are multiple places that send you to the search page) might be to have the link to the search page add a parameter to the url containing the name of an ActionForward that will take the user back to this page. The search page can make note of this forward name, and when the user is finished searching can look it up and return it as the forward from the searchs action. -Original Message- From: Shoaib [mailto:[EMAIL mailto:%5bEMAIL PROTECTED] Sent: Saturday, 13 March 2004 14:01 To: 'Struts Users Mailing List' Subject: Help on struts We are using struts 1.1.

Posting whats in your validation.xml for the form and the bit of your jsp
with your select fields would be helpfull.
If you take the fromDay as an example, you are using
field.getVarValue(fromDay) - if you don't have a var defined in your
validation.xml for fromDay then that would cause the No Name Specified
error - same goes for fromYear, toMonth, toDay and toYear.
As for getting nulls, looks to me again that whats specified for the vars
in your validation.xml doesn't tie up with the names specified on your form.
From your code I would expect something like the following in your
validation.xml
form.
field
varvar-namefromDay/var-name
var-valueformFromDay/var-value
/var
varvar-namefromYear/var-name
var-valueformFromYear/var-value
/var

varvar-nametoDay/var-name
var-valueformToDay/var-value
/var
varvar-nametoYear/var-name
var-valueformToYear/var-value

Do you have the properties in your form correct (i.e in this example
formFromDay, formFromYear, formToMonth, formToDay, formToYear).

Hi,
I am using Struts validator.
One page of mine has dates displayed as MM DD .
All the above 3 are displayed in seprate combo/select boxes.
I need to do some custom validations on these fields.
I wrote a custom class for the same
Looks like -
public static boolean validateDates(Object bean,
ValidatorAction validatorAction,
Field field, ActionErrors errors,
HttpServletRequest request)
{
String actionType = ValidatorUtil.getValueAsString(bean,
field.getVarValue(actionType)); // A hidden form field

field.getProperty());
String fromDay = ValidatorUtil.getValueAsString(bean,

O/P of the above code -
actionType searchPage
fromMonth 2
fromDay null
fromYear null
toMonth null
toDay null
toYear null
It also gives me No Name Specified error.
Point to note is that the all other fields other than 'actionType' are
select boxes. It gives a null for all the field types that are of

James, did you post this on struts-user yet? Unless there's more to it
than I initially see, I think it belongs over there rather than the
developers list.
If I did it right, the reply-to is set there.
The usual way to do this is to populate the Form property in your Action
code, and then when you forward to the JSP containing the html:text
tag, Struts will render the HTML for the form element, including the
value. Note that Struts automatically populates the form from the
request attributes when the user submits the form. I'm not sure whether
you're trying to pre-populate, or to redisplay user input.
This assumes that you are forcing users to go through the Action (not
letting them go directly to the JSP). More information will help us
here, I'm avoiding answering your actual question since you did say
you're new to Struts...
If you do find yourself needing to pull things out of the
request/session, the Struts-EL tags will be useful-- html-el:text
property=searchType value=${someVal} /
