Subject: Validation help: One struts form, multiple actions
Hi,
I am having some trouble with struts validation. Here's the case:
I have multiple actions corresponding to multiple pages.
I have only one struts form for all these actions.
I would appreciate it if someone could tell me how to set up my
validation. I am using ValidatorActionForm for my struts
form. My action
class extends from Action.
Here's a snippet of my struts-config.xml:
action path=/ClientA
type=xxx.xxx.presentation.struts.action.ClientaAction
name=InputDataForm
scope=request
validate=true
input=.app.clienta
/action
action path=/ClientB
type=xxx.xxx.presentation.struts.action.ClientbAction //This is diff
from /ClientA type
name=InputDataForm
scope=request
validate=true
input=.app.clientb
/action
Snippet from my validation.xml:
formset
form name=/ClientA
field property=clientaFirstName depends=required,mask
msg key=lnra.clienta.clientaFirstName name=required/
msg name=mask key=lnra.global.nameMask/
var
var-namemask/var-name
var-value${nameMask}/var-value
/var
/field
/form
/formset
I thought this should be straight forward, i.e., associate your
validation formName to actions and set validate to true in
struts-config.xml. But, its blowing out. Any ideas?
Thanks,
Harsh.

Subject: RE: Validation help: One struts form, multiple actions
I intentionally used /ClientA for my form name as I said, I have one
struts form but multiple actions using that same form. So while
validating, I want to validate only the fields associated with a
particular action e.g. for ClientA action, I want to validate only
fields for ClientA and same for ClientB i.e. I want to validate only
Client B fields for ClientB action. All the fields are using the same
struts form.
That is why I am using a ValidatorActionForm instead of a
ValidatorForm.

RE: page validation in wizzard app
You can use the flow:
POPULATE1- JSP1 - ACTION1 - POPULATE2 - JSP2 - ACTION2 - POPULATE3 - JSP3
All of the POPULATE actions have validate=false in the config. So, if
validation fails after JSP2 is submitted, it forwards to POPULATE2 (ACTION2 has
input=POPULATE2 set), which won't try to validate. It makes for more (2x!)
actions, but also groups actions logically. POPULATE2 gets things ready for
JSP2, and ACTION2 does something with the form from JSP2, and doesn't care about
JSP3 at all. That way, you can move the xxx2 page somewhere else, and just have
to change the mapping in the config (assuming they're not named 1, 2, 3, that
could get a little confusing).
Not sure you'd want to change things at this point, but that's one way to
approach the problem.

Hi Richard.
I can't because of autovalidation. Remember that all my
action have the same
actionForm which is storred in session.
If validation fails i am forwarded to previous action but
this action is not
even executed cause before this previous action can be
invoked validation
process occurs. Page parameter isn't changed and validation
process fails
again...
If validation fails i do not enter any action's execute() method.
2006/5/7, Richard Yee [EMAIL PROTECTED]:
Jakub,
Why can't you reset the page attribute to the appropriate
value in your
Action classes when validation fails.

Richard Yee wrote:
Jakub,
I think the more elegant solution is to do the validations in the
ActionForm validate method and also use a hidden static 'page'
variable in the JSP. Your Action.execute method should be
fairly small
and mainly have code that calls business delegates and
that necessary
for determining where to forward to.

Hi
I have a wizzard application with 5 screens. All user inputs are
collected
in one bean, which is named: viewBean and is stored in
HTTP session.
So each action has the same formBean - viewBean.
I use commons-validator and viewBean properties to validate are
present in
validation.xml with page attributes.
ViewBean extends ValidatorForm and it's validation occurs
automatically - i
have validation set to true for all ACTIONS.
The structure of my app is:
Populate view - jsp -populate view -jsp -populate
view - jsp ...
Population of view happens in ACTION class and can consists of
retrieving
some data from DB, sets these data in HTTP request.
After population process i forward to appropriate jsp to
give user a
chance
to fill the form and to present population process results as for
example
options in html:select.
If form is correct i go to another action which populate
view for a
next
screen (jsp).
If form is not filled correctly i need to show it again,
but i can not
forward to jsp - i need to forward to action that
prepares the form -
that's
why i have my input parameter of action tag set to action which
populate
the view - previous action.
I have a problem with page attribute. Please take a look at the
sample of
processing in my app:
ACTION1 - JSP1 -ACTION2 - JSP2 -Action3 -JSP3 ...
Let's assume that user submits form in JSP2 to action3. After
ActionForm
bean population, page property is set to 2. Next,
validation fails in
Action3 and input parameter of action3 forwards user
to ACTION2.
Before execute method in Action2 is invoked, ActionForm
(viewBean)
validation occurs. The page attribute is still set to 2 ! and
commons-validator tries to validate properties that has page
attribute set
to 2.Obviously validation fails and control is forwarded
to Action1.
Action1
also has validation set to true and validation of
ActionForm occurs
again
with page =2.
Validation fails and control is forwarded to ...
Does anyone have any idea to solve the problem.
My idea is to not to use hidden page parameter in each
jsp action but
set
page property of viewBean in each Action: for ACTION2 sets it to
2, for
Action3 sets it to 3 ...
and to override validate method in viewBean:
public ActionErrors validate(
ActionMapping mapping,
HttpServletRequest request) {
ActionErrors errors = super.validate(mapping,request);
if(errors != null errors.size() 0 )
page--;
return errors;
}
Maybe someone knows more elegant solution, or maybe
architecture of
my app
isn't valid.

Validwhen and whitespace
Struts 1.2.9, Validator 1.2.0.
If I used the required validation, when the user enters whitespace in a form
field, the validation fails. However, when using validwhen it seems that
whitespace is accepted.
In the validation I'm using (below), if the user leaves lastName empty, an error
is generated. However, if the user enters whitespace, the validation passes.
Is this expected behavior? I would expect validwhen to trim, but it doesn't
seem to.
Here's the validation. I'm trying to ensure that lastName is entered if any of
the other parent info is entered:
!-- Validate second (optional) parent --
field property=parent[1].lastName depends=validwhen,maxlength,mask
arg key=labels.lastName/
arg key=labels.firstName/

RE: Servlet Filter?
Frank, thanks for the link to javawebparts. The source code there helped me a great deal. Dakota, thanks for that very detailed explanation of creating my own dispatcher, but I chose to use a filter for now. I'm just not ready to go change the buttons and existing actions at the moment. I'll look at the code you provided and maybe if I get ahead of timeline (yah, right) I'll make the move. So, I'm the big ding bat. I totally whiffed on the what are you going to map to comment made by Frank because I was under the impression that you could define url-mappings with something like /Enroll*.do. I decided to just do a path.startswith(/Enroll) to determine whether to make the check for the session bean. It seems to be working. I started out with configurable paths and ignorelists, but then thought you know what, this is a very specialized filter, I don't want someone to fiddle with configuration parms without thinking about it. My next question is whether there's a mechanism by which I can stick an ActionError in the request so that the error page can display a message to the user using the familiar Struts html:messages tag.

Well, back to the filter then :) One thing you may want to do is have a look at the filters in Java Web Parts (http://javawebparts.sourceforge.net). We have them all implemented with some added flexibility in mapping to paths. At least that way you can only fire it when really appropriate... well... in reality, it's *still* firing, but hopefully doing a lot less work than it might otherwise need to. You can rip off the code for that extra ability (it's in the FilterHelpers class). Then again, I may be micro-optimizing here... maybe for what your filter is doing it won't be that heavyweight anyway. Sounds like that may be the case.

Servlet Filter?
I have a wizard-type flow for an enrollment process. I use a session scoped EnrollmentBean to store the form-beans as they are gathered through the process. If the user cancels the enrollment anywhere along the way, I remove the EnrollmentBean from the session and forward to a Your enrollment has been cancelled page. If, after canceling, the pesky user uses history or the back button and tries to keep going with their cancelled enrollment, we have an obvious problem. I was starting off with the idea of simply checking for the EnrollmentBean in my actions, and if it's gone, forwarding to a You ding-bat, you are trying to finish off a cancelled enrollment page. It seemed like it was going to work, even though I hated having the EnrollmentBean check code in a bunch of different places. Well, the whole thing fell apart when it came to Actions that were just ForwardActions: action path=/EnrollAddressList type=org.apache.struts.actions.ForwardAction parameter=/pages/EnrollAddressList.jsp/ Nowhere to intercept execution (that I know of) before the jsp tries to use the EnrollmentBean. Rats. Now I'm contemplating using a Servlet Filter (never tried that before) to check for the EnrollmentBean in the session for all my Enroll*.do paths, and throw my own EnrollmentDingBat exception if there's no Enrollment Bean. Then use a global-exception to handle it. Two questions to those of you who know more than I do (this is my first Struts application): 1. Does the Servlet filter seem a good solution? 2. If I throw an EnrollmentDingBat exception from said Servlet Filter, will a handler defined in global-exceptions catch it?

Re-use field validations?
Is there any way to define the validation for a common form field once in validation.xml and re-use the validation in other form blocks? This would allow validation.xml to be updated in one place rather than many places, if validation requirements change for a field that is used on many forms. It would also help ensure that I (or others) won't accidentally incorrectly code different validations for the same field on different forms. The benefits will compound if I start writing custom validation routines. I am new to Struts, and this is my first project using it, so I hope I'm not missing something obvious.
