[Nicolas De Loof]

Another option is to use a submit button (that will post the form) and 
CSS to make it look as a link :




   .submit {
   border:0px;
   background-color:#fff;
   cursor: pointer;
   text-decoration:underline;
   }

You need to have the link fire off a JavaScript function that will 
submit the form.  I don't think you'll want to use the  
tag in this case, since you won't need to do anything fancy with a 
request URI.

Here's a really quick example that will run in Internet Explorer.  I 
haven't done enough JavaScript in other browsers to make any 
guarantees with those, but modifications to this shouldn't be all that 
difficult:

Submit
For FORMNAME, you need to use the name attribute of the FORM element. 
IIRC, Struts uses the name of the Form Bean here.  The easiest way to 
be sure is to run your app and view the generated source, though.

Re: [OT]Hashtable Vs Hashmap, Vector Vs ArrayList

[Caroline Jen]

A Map is a class that stores key-value pairs and
provides a way to locate a value based on the key.

The Hashtable class is a synchronized implementation
of the Map interface.

The HashMap is better in terms performance because the
hashing algorithm it uses.   The Hashtable is
synchronized so performance is slightly worse.

As to the difference between a Vector and an
ArrayList:

I. Synchronization
 
Vectors are synchronized. Any method that touches the
Vector's contents is thread safe. ArrayList, on the
other hand, is unsynchronized, making them, therefore,
not thread safe. With that difference in mind, using
synchronization will incur a performance hit. So if
you don't need a thread-safe collection, use the
ArrayList. Why pay the price of synchronization
unnecessarily?
 
II. Data growth
 
Internally, both the ArrayList and Vector hold onto
their contents using an Array. You need to keep this
fact in mind while using either in your programs. When
you insert an element into an ArrayList or a Vector,
the object will need to expand its internal array if
it runs out of room. A Vector defaults to doubling the
size of its array, while the ArrayList increases its
array size by 50 percent. Depending on how you use
these classes, you could end up taking a large
performance hit while adding new elements. It's always
best to set the object's initial capacity to the
largest capacity that your program will need. By
carefully setting the capacity, you can avoid paying
the penalty needed to resize the internal array later.
If you don't know how much data you'll have, but you
do know the rate at which it grows, Vector does
possess a slight advantage since you can set the
increment value.
 
III. Usage patterns
 
Both the ArrayList and Vector are good for retrieving
elements from a specific position in the container or
for adding and removing elements from the end of the
container. All of these operations can be performed in
constant time -- O(1). However, adding and removing
elements from any other position proves more expensive
-- linear to be exact: O(n-i), where n is the number
of elements and i is the index of the element added or
removed. These operations are more expensive because
you have to shift all elements at index i and higher
over by one element. So what does this all mean? 
It means that if you want to index elements or add and
remove elements at the end of the array, use either a
Vector or an ArrayList. If you want to do anything
else to the contents, go find yourself another
container class. For example, the LinkedList can add
or remove an element at any position in constant time
-- O(1). However, indexing an element is a bit slower
-- O(i) where i is the index of the element.
Traversing an ArrayList is also easier since you can
simply use an index instead of having to create an
iterator. The LinkedList also creates an internal
object for each element inserted. So you have to be
aware of the extra garbage being created.

Re: questions about ActionForm, ValidatorForm, etc.

[Hubert Rabago]

The ActionForm (there is no ActionFormBean) is the basic form bean. 
You can use this or any subclass for Struts form beans.  You use them
to hold the values passed from the browser.  These values can come
from a , from multiple s through multiple pages, or even
from parameters at the end of a URL (like
"/webapp/path.do?fname=Bill&lname=Ding").

For ValidatorForm, DynaValidatorForm, and DynaValidatorActionForm, see
http://marc.theaimsgroup.com/?l=struts-user&m=110375387629389&w=2

ValidatorActionForm is the non-dynaform version of
DynaValidatorActionForm.  What this means is, you can specify how it's
validated through XML, and the Validator plugin will find the set of
rules to apply to it based on which path it gets submitted to.

LazyValidatorForm is a dyna form that doesn't need to have its fields
specified in a config file.  You can declare a bean to be a
LazyValidatorForm and it'll create the necessary fields as values are
passed to it.

BeanValidatorForm is a new form bean which can be backed by a POJO. 
Through this class, you can use your own business object to back a
form bean.  I believe this will work better if you're using 1.2.5 or
higher.

Note that ActionFormBean is a configuration object,
DynaActionFormClass is a DynaClass implementation; neither of these
are ActionForm subclasses and should not be used as form beans.

questions about ActionForm, ValidatorForm, etc.

[Daniel Watrous]

It would seem that every form in my web application requires a form class 
(JavaBean).  I think I understand that a Form is a loose term, not necessarily 
referring to one  tag set on a given page, but rather a form may 
span many pages and requests.  Is this correct so far?

I think that I also understand the mechanism DynaActionForm, which builds a 
type of "Bean" from an XML definition of the form, rather than hardcoding an 
ActionForm subclass for the form.  These two beans also provide a validate 
method (one inherited) which I can override (optionally) to perform validation.

My question relates to several other classes that all seem to do similar 
things, but I'm not finding clarification about how to use them in the 
Javadocs, or User/Developer documentation.  Most of them relate to validation.  
Of the following list, when is the most appropriate time to use each one, and 
what are their differences?

ActionFormBean
DynaActionFormClass
BeanValidatorForm
DynaValidatorActionForm
DynaValidatorForm
LazyValidatorForm
ValidatorActionForm

I will continue with the Javadocs.  Please send links to documentation that may 
clarify the use of each of these classes.  Thanks in advance...

RE: How to view the actual HTTP generated by a struts action.

[Karr, David]

This could be done with Ethereal, which allows you to listen in on
traffic without having to manually insert an observer in the chain.  If
you use "Follow TCP Stream" after generating the packet data, you can
see all the back and forth HTTP traffic in a single buffer.

RE: Dispatch action and java script?

[Durham David R Jr Contr 805 CSPTS/SCE]

> 

The problem could be that you aren't returning anything.

Try doing something like this:

   onclick="return validate();"

Then:

   function validate() {
  if (...) // fails
 return false;
  }
  // else
  return true;
   }

So, you return a Boolean from the validate function that is then
returned to the "onclick" event.  False means halt the normal event
propagation which, in this case, is form submission.



> I don't know if I can do this with dispatch action.  

Well, if I understand you correctly, you are having problems with the
Javascript validation.  Or, are you having problems with the
ActionForm's validate method.  If it's the latter, then maybe this will
work for you:

public Dispatch ... {

public dispatchedActionWithValidation(...) {

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

if (errors != null && !errors.isEmpty()) {
saveErrors(request, errors);
return mapping.findForward("errorPage");
}

...

}

Then in your struts-config action mapping, you would set:

 validate="false"

I can explain why you might want to use this method, if you like.

Re: Dispatch action and java script?

[Dakota Jack]

In a way, Nadia, your problem is not a problem.  If you want to "make
sure one of the radio buttons [you] have on the page is clicked", then
all you really want is to make sure the value of that button is
available in the processing of the request.  You can do that without
the radio button even being on, or even existing.  Right?

Re: =

You need to have the link fire off a JavaScript function that will 
submit the form.  I don't think you'll want to use the  tag 
in this case, since you won't need to do anything fancy with a request URI.

Here's a really quick example that will run in Internet Explorer.  I 
haven't done enough JavaScript in other browsers to make any guarantees 
with those, but modifications to this shouldn't be all that difficult:

Submit
For FORMNAME, you need to use the name attribute of the FORM element. 
IIRC, Struts uses the name of the Form Bean here.  The easiest way to be 
sure is to run your app and view the generated source, though.

Congrats. So this your demo site? If it is in production, you may
want think about getting a web designer to help you with the layout.
It kind of reminds me of a 1998 webpage.

Hi 
Thanx for the reply Brandon, i was able to get it
working after converting the Hashtable to ArrayList
having LabelValueBean like this
Hashtable ht = mapsContextData.getAS400List(oCtx);
Enumeration enu = ht.keys();
 ArrayList data = new ArrayList();
  while(enu.hasMoreElements())
 {
 String key = (String)enu.nextElement();
 String value = (String)ht.get(key);
 logger.debug("key is " + key + " value "
+ value);
 data.add(new LabelValueBean(value, key));
 }
But really hoped to be able to use Hashtable rather
then adding this code

Re: Handling the exceptions in struts

[Kishore Senji]

org.apache.struts.action.ExceptionHandler by default puts the
exception in the request;

request.setAttribute(Globals.EXCEPTION_KEY, ex);

So, if you have a custom ExceptionHandler, just make sure you call
super.execute() so that setting of the exception is done for you. (or
You have to set it in the request explicitly). In the error.jsp you
can retrieve that execption from the request.

Hi,

This works fine but I would like to make sure that one of the radio buttons

I created a javascript function that will check if a radio button is

I don't know if I can do this with dispatch action.  It looks like I can't

Another way of doing it would be to create another form for this action with
just one field and turn on the validation where I would check the value of a
radio button.  

What is a better way of doing it?  What is a best practice?

Re: Handling the exceptions in struts

Shoot.  Didn't read your message closely enough.  This only applies to 
exceptions thrown within a JSP page and handled by the JSP exception 
handling mechanism, and you're talking about the Struts exception 
handling mechanism.

Sorry 'bout the noise.

Miles, you can capture a stack trace from any throwable using a 
technique
like:

 ByteArrayOutputStream baos = new 
ByteArrayOutputStream();
 (new Throwable(s)).printStackTrace(new 
PrintStream(baos));
 return baos.toString();

The result could be logged.
Hope this helps.

Dispatch action and java script?

[Nadia Kunkov]

Hi,
I implemented DispatchAction and I have a page with three submit buttons, each 
executes a method in my dispatch action.

This works fine but I would like to make sure that one of the radio buttons 
that I have on the page is clicked.
My validation is turned off for this action since there are no input fields to 
validate.
I created a javascript function that will check if a radio button is clicked.
So now I have 

I don't know if I can do this with dispatch action.  It looks like I can't 
since I never go into the validate() function, but go right to the action when 
I click the button.

Another way of doing it would be to create another form for this action with 
just one field and turn on the validation where I would check the value of a 
radio button.  

What is a better way of doing it?  What is a best practice?

Thanks for your help.

From Section 2.4 of the JSP 1.2 specification:
"If the errorPage attribute of a page directive names a URL that refers 
to another JSP, and that JSP indicates that it is an error page (by 
setting the page directive’s isErrorPage attribute to true) then the 
'exception' implicit scripting language variable of that page is

You might investigate these links:

Section 4.5 here:

and the corresponding javadoc here:

Opinions needed - My plan for directing navigation afters session timeouts and update actions?

[john . chesher]

I have two situations I am trying to address with one generic solution:

1) For every update action, I had to maintain two separate "result
confirmation" JSPs, one stating "Update Successful" and one "Updated failed
due to system error.  Try again later."  (must be a system error, as any
data validation errors would have been returned to original data entry
JSP.)  Each of these also has a button with a unique link to take it to the
appropriate action to build what should be the next view for that user (I
want to be able to bounce them back to a page that was most recent or
appropriate for where they were in the application.)

2)  On session timeout, I want to bounce the user to a login page, then
bring them back to the page/action they were attempting to go to, or the
most appropriate location, based on the application knowing only the user
id of the user and no other context.

If you could review my plan below and let me know if it is sound from a
Struts perspective OR whether there are Struts best practices to accomplish
the same thing in a more elegant way, that would be great.  I am pretty
sure there is a bug in how I propose using the various session attibutes
below, but please don't worry with that - I'll sort it out when I
implement.  I am really seeking an opinion on the overall approach.
Thanks!

MY PLAN:

Keep three attributes in the session object up to date at all times:
a)  previousAction  -  the most recent action completed by the user
b)  currentAction  -  the next action the user was attempting when the
error or session timeout occurred
c)  nextAction  -  the next action that should be invoked after a
successful action (ONLY after successful actions)
c)  previousActionResult  -  the message to be displayed on
actionResult.jsp (after ALL update actions, whether successful, failed, or
timed-out)


Psuedo-code for a session timeout scenario:

User is on ChangePasswordDef and presses button to process change with
ChangePasswordAction

AuthenticationFilter (this is a filter that precedes ALL actions.  It
checks authority of the user to execute the action, logs that the user
executed the action, and looks for session timeout)
  set previousAction = currentAction (no longer prev action.  In fact,
null in this scenario.)
  set currentAction = ChangePassword
  If new session (session timed out before this action)
set previousActionResult = "...inactive too long..."
forward to actionResult.jsp

actionResult.jsp
  display previousActionResult
  render OK button to go to GoToLoginAction

GoToLoginAction
  forward to LoginDef (Tiles)

LoginDef
  invoke LoginAction

LoginAction
  process login successfully
  If currentAction != null
forward to actionResultAction

actionResultAction
  If currentAction = "ChangePassword"
forward to ChangePasswordAction

AuthenticationFilter
  pass authorization check and do not detect session timeout
  if current action != previousAction
set previousAction = BuildHomeViewAction
currentAction = ChangePassword

ChangePasswordAction
  (finally where the user wanted to be!)

Validating DynaBean nested beans with a custom validator.

[Daffin, Miles (Company IT)]

Dear All,
 
I have a DynaValidatorActionForm like this:
 








When the related form is submitted the action adds the 'newPerson' to
the 'personList' and replaces newPerson, on the DynaBean, with a new
PersonFormBean. This all works fine. Now I want to add declarative
validation for the newPerson, so only valid newPersons reach the action
code that adds them to the list. 
 
The thing is that PersonFormBeans (in this example) have a start and end
date (a period). The validation rules for these fields are:
* start date and end date must be dates (dd/MM/)
* start date must be before end date
* end date must be after or equal to today
* etc...
 
So, you see, apart from the first rule, this goes beyond what can be
achieved by plucking out the fields from the nested bean and using the
default set of simple field validators shipped with struts (required,
date etc.). (Even if you disagree that these validation requirements
cannot be met in using the default validators please read on. This is
just an example.)
 
I have created a new validator that I want to handle the entire nested
PersonFormBean: personValidator.
 



 
public static boolean validatePerson(Object bean, ValidatorAction va,
Field field, ActionErrors errors, HttpServletRequest request)
{
PersonFormBean personFormBean =
somehowGetTheBloodyPersonFormBeanOffTheBean(bean);
// Do the validation directly on the personFormBean.
return true;
}
private static PersonFormBean
somehowGetTheBloodyPersonFormBeanOffTheBean(Object bean)
{
// How do I implement this?
// It has to be generic, in case I change my mind about the type of
the bean,
// e.g. make it a simple bean with getters and setters instead of
using the DynaBean...
return null;
}
 
Would you: 
a) grab the nested PersonFormBean from the main, parent bean and then
work directly with this? If so how? Is there a utility method somewhere?
b) grab individual fields from the nested bean using BeanUtils methods
(or other - feel free to advise).
 
Your thoughts/urls would be appreciated.
 
Many thanks.

Re: error with logic:iterate on dynabeans

[Olasoji Ajayi]

After going thru some source codes in the struts package, i discovered that 
the problem hat to do with formating, the last two colums of my table are 
DATE formats which translated to java.sql.date type in java. the bean taglib 
was looking for a resource ot determine how to format the data on those 
fields but since i did not create any resource configurations, it was 
looking for what was not there. i had to hard code a format on the 
bean:write tag using the format attribute. i dont think this is a neat idea 
especially for beginers like me who want to whip up a working application 
with as little advanced configurations as possible so we can learn one thing 
at a time, (resource bundles/intenationalizatin, jdbc, etc) and still get 
struts to give us some workable defaults.

Re: How to detect Cancel button i pressed ?

[Nicolas De Loof]

Manisha Sathe a écrit :
Hi Nicolas,
Thanks for the response,
1)I tried this, but giving me error. Pls would u mind giving some code example ?
 

use  in your JSP (do not set property !)
use isCanceled(request) in action. Is cancel was used to post the form, 
it will return true.

2)About exception - do u mean to say my own method common to all ? This also if u can explain with code example would be of great help. 
 

I set a global ExceptionHandler in struts config to catch all 
exceptions. It logs them for debug and forwards to an error page.

Thanks once again,
regards
Manisha
Nicolas De Loof <[EMAIL PROTECTED]> wrote:
You can check for cancel in actions using
isCanceled(request)
Struts cancel tag uses a magic value that this method will detect 
(formbean validation is also skipped)

About exception, I used to set a global exception handler that logs 
exception stack and forwards to a generic error page.

Nico.
Manisha Sathe a écrit :
 

I had posted it before - might hv missed the response. I want to check whether 
Cancel button is pressed, if yes then want to redirect it to another page
Also how to handle th Exceptions. I am catching many exceptions inside my Action Handlers. 
what shall i do with them ? Currently just printing the error messages on System.out, but what is the good practice to handle exceptions ? Close all Resultsets/ connections and redirect to error page ? write some standard routine ? 

In struts-config i have given mapping to "errors" as global forward, but what 
if exceptions occur inside my common classes ?

I am trying to have a common routine for Exceptions.
 
Inside Action Class I am calling this common method, passing
ActionMapping as parameter, doing some stuff like logging and then
forwarding to error page.
 
But the problem is what if i get exception in my normal Common Java

error page ?
 
I am bit confused in how to handle exceptions in effective way. Pls

R: Handling the exceptions in struts

[Amleto Di Salle]

Hi,
You can use the tag "exception" inside the tag action for local
exception, or global-exceptions for global ones.

For example:

 
 


or





The attribute "path" can be a JSP page or a tiles which contains the
html:errors tag.
The attribute key contains a resource message.

Re: How to view the actual HTTP generated by a struts action.

Yet another tool that might be worth checking out is Fiddler

that I found quite
 helpful when analyzing HTTP traffic.
