Pre-populated option values of a select not got on Submit
I have a select/option in my JSP like this: html:select size=3 styleClass=menu styleId=catsel property=category multiple=yes html:options collection=catSelList labelProperty=displayName property=id/ /html:select I have also defined the bean for catSelList: bean:define id='catSelList' property='catSelList' name='editEPForm'/ In the Form java file, I have the method public Collection getCatSelList(), that returns the list of values that needs to be displayed in the select/option menu. The page works fine when opened. The values that need to be displayed in the options are displayed correctly. But the problem occurs on submit. Whatever I do, the property category (which refers to the html:select) is always null. Even if I add values from another list into this select/option menu, the value of category on submit is null. How do I rectify this problem? This is what I want - if the user doesn't change anything in that field, the pre-populated values needs to be stored under category. If he does change anything, the new values needs to be stored under category. How do I do this? Thanks, Sridhar
RE: problem in formbean
Is this value a long or int, or whatever numeric value, And u r trying to enter characters in it then validation fails ? Cuz if so the Struts won't be able to populate the long with the string value U entered and in this case it'll keep it's old numeric value. In case of validating numeric fields always make them Strings in the form, To be able to keep the updated value after the validation fails. -Original Message- From: notify@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of prkumar_1234 Sent: Thursday, November 30, 2006 5:46 AM To: struts-user@jakarta.apache.org Subject: problem in formbean I got some problem in struts can you please help me. 1) in jsp iam displaying values from javabean in textboxes.(i can change these values) 2) when i submit with modified values , iam doing validation in formbean. 3) When validatio fails i formbean returning to same jsp but it is displaying old values not modified values can you give me some hint how to do this. thank you verymuch - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Does Struts 2 solve the action chaining problem?
Craig and Mark, Thanks a lot for pointing out the Preparable interface. I think that solves a major problem with Struts 1. I'm yet to experiment heavily with WW/Struts 2, but I feel like the Interceptor concept is a very powerful approach, though a bit dangerous if not well controlled. Craig, We, actually, decided that we don't want to get into JSF yet. But if this prerender method is equivalent to the onPageLoad() method in ASP .NET, then it's a very important piece that is really missing from the JSF spec. Yujun, Your idea is brilliant and it never crossed my mind. If we stick with Struts 1, I think I will try that. Christopher, I really wonder if the Struts you're talking about is the one I've using for years now!! The Struts I know sucks big time when it comes to action chaining. I'm afraid I don't understand how defining two mappings, one with validation turned on and the other turned off, solves the first problem! As for the second problem, your solution still involves action chaining which should be avoided unless you've done something equivalent to what Yujun did. Thanks everyone for your help. -Original Message- From: Christopher Schultz [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 29, 2006 5:36 PM To: Struts Users Mailing List Subject: Re: Does Struts 2 solve the action chaining problem? -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Tarek, Tarek Nabil wrote: One of the problems with Struts was that if you had a page that requires some setup and this page submits to an Action, then you would not be able to set validate to true on that action because if validation problems occur then Struts will take you directly to the input JSP without performing the setup and your JSP wouldn't work. A solution to that would be to specify the input of the action as the setup action, which means you're doing action chaining and Struts is not good at that (it will reset your form among other things). The solution of choice for us so far was to call validate() ourselves in the action and if a validation problem occurs then we call the setup method (eventually you start using your action methods as an API which still was not good). I totally disagree. If you have an action that you want to use like this, you can always set up two different mappings -- one that /does/ validate and another that does /not/ validate. My experience has been that Struts is very good at action chaining... in fact, that's the major advantage of Struts in the first place: the ability to map URIs to actions and specify their relationships through forward mappings. Another problematic scenario is the case when you're editing some database record for example. When you go to your setup action for the first time, you will populate drop down lists for example, and then load the existing values from the database to your JSP fields. If the user attempts to save and some problem occurs then in the setup action, you will need to again populate the drop down lists, but you will NOT want to overwrite the user's inputs with the existing data. This is very similar to the first problem, but you would also need to pass some flag to the setup method to tell it whether to copy the data from the database to your ActionForm. In this case, what you want is something like: LoadAction - EditAction - Display form Form submits to SaveAction, which has EditAction as input (not LoadAction). This is pretty standard stuff, and works beautifully. Does Struts 2 or even WW 2.2.4 solve that problem in an elegant way? I really hope so, since Struts 1.x also does. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFbYyx9CaO5/Lv0PARArpHAJ0U3fHybMWepSZxPjciDU3+6M2PwQCgoy8B FRlfdQsyONpgqGvrHBuZuFw= =EbD/ -END PGP SIGNATURE- DISCLAIMER This email and any files transmitted with it are confidential and contain privileged or copyright information.

The easiest way to do this is to turn off automatic validation in your

ActionMessages errors = form.validate(mapping, request);
if ( errors != null errors.size() 0 ) {
LOG.warn(Errors detected!!);
return mapping.getInputForward();

Re: Does Struts 2 solve the action chaining problem?
Action Chaining
First, we usually define action chaining as creating a move action
by having a copy action forward to a delete action. Simply going
from one action to another isn't a classic example of harmful
chaining. The key point is whether only one action resolves the
business use case.
Classic action chaining is considered harmful because it implies that
the Actions have become a business facade. Any Action should be able
to call facade.copy and facade.delete from a move Action. Better yet,
the facade should provide a move method, and implement it any way it
likes. We should not feel like we need to reuse multiple Action
classes to solve one business use case. Struts 1 Actions were intended
to be what Martin Fowler calls a transaction script, where move is
one transaction, not two.
The design of Struts 1 made action chaining difficult because s1
repopulates the request on every forward. When people start to use the
S1 actions as an API, they want to do things like change properites on
an ActionForm, and are surprised when the framework resets their
changes!
The Struts 2 group does discourgage classic Action chaining, because
it implies the business API is underdevelpoed. Albeit, we do provide a
action chaining result that copies the properties from one Action to
the next. The interceptor stack and result are processed for the
chained action, but the request doesn't pass back through the
container.
* http://struts.apache.org/2.x/docs/action-chaining.html
So you can set a flag on the copy action and have it picked up by the
delete action. This is *not* considered an ideal practice, since
coupling individual Action classes complicates the API, but it's there
when people choose to use it.
So, yes, Struts 2 has an elegant solution for action chaining, if you
choose to use it.
Control preparation
As mentioned, Struts 2 solves the control population issue via the
preparable interface. Another solution is to use the action tag to
execute an Action in place.
* http://cwiki.apache.org/confluence/display/WW/action
One way to use this tag is to put a control on a snippet JSP that is
rendered as a result of an Action that does nothing but create the
object that populates the control. The action tag sets
executeresult=true, then control markup will be included into the
page (like a tile), after the action executes.
In effect, exectuteResult actions can be used like a tag that can run
its own action before emitting the markup.
Input.jsp
%@ taglib prefix=s uri=/struts-tags %
s:form
s:action name=languages namespace=/ActionTag executeResult=true/
s:action name=colors namespace=/ActionTag executeResult=true/
ssubmit/
/s::form
Languages.jsp
%@ taglib prefix=s uri=/struts-tags %
s:select
tooltip=Choose Your Favorite Language
label=Favorite Language
list=favoriteLanguages
name=favoriteLanguage
listKey=key
listValue=description
emptyOption=true
headerKey=None
headerValue=None/
Languages.java (execute)
public String execute() {
favoriteLanguages.add(new Select.Language(EnglishKey,
English Language));
favoriteLanguages.add(new Select.Language(FrenchKey, French
Language));
favoriteLanguages.add(new Select.Language(SpanishKey,
Spanish Language));
return SUCCESS;
}
struts.xml (Input, Languages)
action name=Input
result type=plaintextInput.jsp/result
/action
action name=Languages class=app.Languages
resultLanguages.jsp/result
/action
The advantage being that the Languages action could be dropped in
whereever the Languages control is needed, and that the Action for
the form doesn't need to know how to populate the Languages control.
Now, the Action is going to be hit every time the page is rendered,
but so long as you are using a caching data access layer, like IBATIS
or Hibernate, it will end up being a memory-to-memory transfer, rather
than a database access.

Retrieving DynaValidatorForm values with JSTL
Hi all,
I have a form stored within the session and am trying to dump some of the
Form values in the presentation using JSTL.
Specifically something like
Country : c:out value=${sessionScope.SubscriptionProcessForm.country}/
The form's name is
SubscriptionProcessForm and the value to be retrieved from the form is
country.
Obviously I'm looking to retrieve the value without a scriptlet.
Is there a way?

RE: Retrieving DynaValidatorForm values with JSTL
Thank you Wendy
For all,
In JSP pages using the Struts Taglib, attributes of DynaActionForm objects
can be referenced just like ordinary ActionForm objects. Wherever a Struts
tag refers to a property, the tags will automatically use the
DynaActionForm properties just like those of a conventional JavaBean.
So the code becomes
bean:write scope=session name=SubscriptionProcessForm
property=country/
Thanks again.

No... if you're using JSTL, don't go back to bean:write.

The DynaActionForm properties must be accessed through a slightly

Struts 2 and passing data using interceptors
Hi. I'm new to Struts and have a question regarding how data is passed from an Action (in Struts 2) to the JSP which one is redirected to after the action is executed. Reading the documentation on Struts 2, I've found that using the Scope Interceptor one can specify Action properties to be bound to the session or application scope. This is configured in struts.xml with the interceptor-ref name=scope tag and then setting the appropriate parameters. See http://www.twdata.org/backups/WW/scope-interceptor.html Now, say I access an EJB from an Action. The method of the EJB returns some data. Is it good programming practice (in Struts) to store this data in the session object, later to be accessed from a JSP? This should allow me to pass the data, but perhaps there is some other alternative which is preferred. Storing information in the session object would maybe be good practice for data such as user id, contents of a shopping cart, etc. The scope I believe I am interested in is request scope, since the data returned from the invoked EJB method is data from an Amazon.com search, only to be used in the JSP displayed immediately after the execution of the Action. Would the preferred method in my case then be to implement the ServletRequestAware interface in the Action and store data of interest in the request object? I can't find any interceptor that does this. I'm sure one can create user defined interceptors, but if there's a standard method for this functionality provided by the framework, then I guess that would be the preferred way to go. I'm grateful for any input on the matter.

struts 2 newbie question
Hello,
I'm working through the official struts 2 tutorial
(http://struts.apache.org/2.x/docs/validating-input.html ...)
and I don't understand this stuff :
in struts.xml
action name=Login_* method={1} class=tutorial.Login
the tutorial says :
The method={1} attribute is replaced with method=input.
Why ? Can someone explain me why it is replaced by this particular method,
and give me another simple example if possible.
thanks

Re: Struts 2 and passing data using interceptors

Re: Does Struts 2 solve the action chaining problem?
On 11/28/06, Tarek Nabil [EMAIL PROTECTED] wrote: Hi, One of the problems with Struts was that if you had a page that requires some setup and this page submits to an Action, then you would not be able to set validate to true on that action because if validation problems occur then Struts will take you directly to the input JSP without performing the setup and your JSP wouldn't work. A solution to that would be to specify the input of the action as the setup action, which means you're doing action chaining and Struts is not good at that (it will reset your form among other things). The solution of choice for us so far was to call validate() ourselves in the action and if a validation problem occurs then we call the setup method (eventually you start using your action methods as an API which still was not good). Another problematic scenario is the case when you're editing some database record for example. When you go to your setup action for the first time, you will populate drop down lists for example, and then load the existing values from the database to your JSP fields. If the user attempts to save and some problem occurs then in the setup action, you will need to again populate the drop down lists, but you will NOT want to overwrite the user's inputs with the existing data. This is very similar to the first problem, but you would also need to pass some flag to the setup method to tell it whether to copy the data from the database to your ActionForm. Struts 1.x works perfectly well in the above scenarios. You may want to check out the overview of Struts action usage in Struts wiki [1]. You can have one action handling both setup and input or you can have two separate classes. Also, you can have two different action forms or one action form. Struts populates an action form automatically, which seems like too much automation to me, but this cannot be changed now to ensure backwards compatibility. The specifics of handling form bean repopulation depend on chaining approach. If you use in-server forwarding, then you will have to place a token into the request object in the first action, and check this token in the target action (actually, you will probably be checking this flag in the form bean). If flag is there, this means that the action was chained by forwarding, and you have to prohibit updating a form bean. You can do this by putting an if into each and every setter of the form bean. Quite clunky. If you use a different action form for a chained action, you may want to define getters only, or to have setter methods that do not correlate with URL parameters. If you use redirection through browser, then just do not append any parameters to the target URL, this way a redirected request will be clean of parameters and Struts will not populate a form bean, because it has nothing to populate with. What is more, you can use one session-scoped form bean for both actions, it already has been set up, so you don't it to reinitialize it.

If not this specific implementation, an otherwise clean way to handle view preprocessing after a validation failure.

The Struts I know sucks big time when it comes to action chaining.

As for the second problem, your solution still involves action chaining which should be avoided unless you've done something equivalent to what Yujun did. I suppose I've never tried to modify the state of the request (or form bean) such that re-interpreting it across action invocations is relevant. I typically get information out of a form bean ASAP and then use that for some other operation (most often database interaction). Then I discard the form bean. If I have to re-read the form bean, it's in the same state in which I left it. I guess if you store a lot of state information in your form beans, and you mutate that information in your actions, you might end up fighting against Struts. As it is for me, forwarding from one action to another (that both use the same form bean) results in no problems except a slight performance hit for re-populating the bean and validating it when entering the second action. I never use beans that contain anything but Strings, so no conversion ever needs to take place. It looks like my mode of use has resulted in me never realizing what a PITA it might be when attempting to chain actions in this way. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFb2by9CaO5/Lv0PARAtveAJ9AyWu4w0x7CUOuRvxXDjoKcVKbxwCfXCvc licIhQWz58NCiqrqaR8XwO8= =cSgU -END PGP SIGNATURE- - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I think that this taken together with the action mapping:

Will result in the input being stripped off the end of Login_input and
being put into {1}. I think that's what the Login_* basically says in the

That's pretty slick. I didn't know about this. I think I might start using

private MySessionBean getSessionBean () {
// Some code to get your EJB.
}
}
In your JSP you can display this data with the s:property tag:
s:property value=%{dataRetrievedFromSessionBean} /
That's it.
You don't need to mess with Session scope, other interceptors, or any of
that stuff. It's very simple and elegant. Almost too much so. It eluded me
for a while, but now I'm really starting to get it, and it's good.

Re: Struts 2 and passing data using interceptors
What makes it not thread safe? If you are thinking in terms of s1, then
yes, but s2 actions are not reused and can therefore keep state as you
normally would have had to put in a s1 formbean.

No problem. If your thinking of Actions from the perspective of S1, yes,
this would be horribly non-thread safe. In S2 an action instance is created
for each request. They are not singletons. So, this is fine.
Since I know virtually nothing about S2, I may be completely missing
something like action instances now live in the session or something
crazy like that.
They don't live in the session. In a sense they live in the request scope. I
say that because the Action itself also takes on the role formerly done by
the ActionForm in S1. It's just a JavaBean with setters and getters that is
used to store the information you're interested in, the stuff submitted to
you and what you want to present in your view.
In S2 if you have an accessor for let's say firstName (i.e. getFirstName()
and setFirstName() ) on your Action class, and you have a firstName input in
your HTML form, S2 will call setFirstName() on your action with the
submitted value. This gives you access to the parameters submitted by your
user.
It's really quite simple and elegant. You can also use any JavaBean you'd
like as your form in S2 if you want. (cf:
http://cwiki.apache.org/WW/model-driven-interceptor.html)
Likewise anything that you want to display in your view would also be a
property of your Action. Just get the data in your execute() method and make
it available via a getter and you can display it via your view.

Re: problem in formbean
Hi Prem, At the time of landing the page, you are showing some values. That values are taken from DB. Once error coming you are redirecting to the same page. but with the error value. This is your problem right? this can be easily solved. you are showing the values taken from formbean. At the time of error, the new value (error value) would be stored in the formbean. so that error value has been shown to you. show the value from DB. your problem will be solved. sorry for my english prkumar_1234 [EMAIL PROTECTED] wrote: I got some problem in struts can you please help me. 1) in jsp iam displaying values from javabean in textboxes.(i can change these values) 2) when i submit with modified values , iam doing validation in formbean. 3) When validatio fails i formbean returning to same jsp but it is displaying old values not modified values can you give me some hint how to do this. thank you verymuch - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] BY Thamizharasu S - Everyone is raving about the all-new Yahoo!

Re: How to set %@ page session=false %, globally?

Re: s2 image submit button and methods
Thanks for bringing this up. I created a ticket and have fixed the issue: http://issues.apache.org/struts/browse/WW-1532 The problem is complicated by the fact that IE doesn't submit the button name in addition to the .x and .y. All cases should be properly handled now. Don On 11/28/06, Ing. Andrea Vettori [EMAIL PROTECTED] wrote: Hi, yesterday it took me a day to understand and resolve a problem so I think it can be useful to share it; maybe someone can explain a better solution. I have a form with more than one submit button. The submit buttons are images so I used the s:submit type=image method= ... tag on all but the default button. The problem is that since the image button is considered by the browser similar to an imagemap, if the button is called btnA, the browser submits btnA, btnA.x and btnA.y request parameters, where the .x and .y are the coordinates of the click inside the image. I think this cannot be disabled on the browser since it is required by the HTML specifications. Now this cause problems when the parameters are used by the action to call the appropriate method. If I have a button like s:form action=anAction ... s:submit type=image method=aMethod ... in the HTML you get something like input type=image name=method:aMethod ... and when the request is submitted the browser sends method:aMethod, method:aMethod.x and method:aMethod.y parameters. This cause the framework to try to execute the aMethod.x() method on the action class which generate an Exception !!! I've tried to filter the parameters with ParameterNameAware but the parameter that starts with method: are not passed to the acceptableParameter method. So I extended the parameters interceptor and overrided the acceptableParameter function and even if now I see the parameters on the method, even if I reject them, the framework use them to try to execute the method in the action. The solution I used is to have the image submit to set a value (like s:submit type=image name=aName value=aValue and use that value inside the execute method of the action to call the appropriate method. But I'm looking for a better solution. I also think that since this will be a common problem, it should be addressed by the framework automatically rejecting method:xxx and action:xxx parameters that ends with a .x and .y. Thanks -- Ing.
