Re: Struts validator Regular Expressions
Hi,
this should be very close to \d{1,3}[.]\d{1,3}[.]\d{1,3}[.]\d{1,3}
I need to validate an IP address and I don't know how is the syntax in the
validator config file.
take your time to study this:

It's worth the trouble, regex rox !

Re: Submit Once, Validate Twice -- but how ?
Hi,
thank you, that helps.
Now i still need to know how to access the input page (set in action
mapping with the input="sample.jsp" tag)...
I don't have sample code but are you looking for something like this:
// in Action execute...
ActionErrors errors = new ActionErrors();
// add errors...
...
// set in request
request.setAttribute("org.apache.struts.action.ERROR", errors);
// forward to same page...
Thanks

Submit Once, Validate Twice -- but how ?
Hi, just read this article on husted.com and it seems to be good advice. When the user submits a page, passes validation without errors, is there a chance to validate business logic in the action ? Therefor i need to - make my validation, - get an errors object, - store the error, - put the errors object in the request and - return to input page. Has anyone some sample code / suggestions / articles / sources hoe to achieve this ? Thx - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
HowTo logical date validation
Hi all, i´m looking for some kind of 'logical date validation' which means that dates like '2004-02-31' are filtered out and sent back to input page. Has anyone ever done this before (i´m sure you have ;-)) ? Are there any sites dealing with this problem ? thanks for your reply... - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
How to validate selects
Hi all, i´m doing some selects like this: Now, i have to validate, that the user has made his choice, which means that the 'foo' property is notNull. Does anyone have an idea how to realise this in struts ? Thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
rePost: How to set the selected value in an select rendered by optionsCollection
Hi all,
i´m reposting my problem trying to be a little bit more specific. This
problem is very important for me, though i made another 'book like'
example to show where i am.
There are three beans playing in my theatre:
1. the CommonValuesBean which stores frequently asked data for my JSP
HTMLForms
2. the CustomerBean which is an buisiness objekt representing a customer
3. the DynaForm which stores data coming from my JSP HTMLForms.
First of all, the CommonValuesBean is initialised. Therefore, i´ve got
the sessionListener that puts data in it, anytime a new session is creatd:
public void sessionCreated(HttpSessionEvent event) {
CommonValuesBean commonValuesBean = new CommonValuesBean(); // create
new bean instance
HashMap countries = new HashMap(); // Create new map
countries.put("countryCode1","country1")
countries.put("countryCode2","country2")
countries.put("countryCode3","country3")
countries.setCountries(countries); // Our example map is now stored
HttpSession session = event.getSession();
session.setAttribute("commonValuesBean",CommonValuesBean);
}
Now we begin to deal with the customers. There is listCustomers Action
that shows all of the customers. You can klick one to
get more detailed information using the customersDetailsAction:
public class customersDetailsAction extends Action
{
private Customer customer = new Customer();
public ActionForward execute(ActionMapping mapping,ActionForm
form,HttpServletRequest req,HttpServletResponse res)
throws IOException, ServletException
{
customer.setFirstName("Frank");
customer.setLastName("Schaare");
customer.setCountry("country2");
req.setAttribute("customer",customer); // storing customer in request
return mapping.findForward("customerShowDetails"); // mapped to
customerShowDetails.jsp
}
}
The customerShowDetails.jsp looks like this:
.
. tons of markup
.
.
. again: tons of markup
.
The problem is, that the renders a select like
this:
country1
country2
country3
i desperately NEED to render the select like this:
country1
country2
country3
because my customer lives in country2 !
Is there any way to tell Struts to do this ?

Re: How to set the selected value in an select rendered by optionsCollection
Hi Hubert, This would only be true if the action that was called specified that form in its mapping. If this is a preprocessing action (that's being called to provide an HTML form with data to show), and there's no "name" attribute to tie a form to it, Struts will not create/populate a form (because it wouldn't know what form to create). Sorry, but i guess you are wrong. The declared formBeans are digested during ActionServlets.init(). If you have a tool that is able to visualize your Java Objects like the 'variables' view in Eclipse, you will see the following right after applications startup, when setting a breakpoint in any action: mapping/moduleConfig/formBeans which is a HashMap. All your declared beans are right there. Does anyone know the right way to access this HashMap ? Anyway, we became very far away from my optionsCollection problem. I´ll try to repost it trying to be a little more specific. CU - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How to set the selected value in an select rendered by optionsCollection
Hi Wendy,
thx for your reply, but there are some questions left:
this is where i am: there is my business object 'sb' and the upcoming
DynaActionForm. sb extends ActionForm, there should be sb.execute().
Nope. It goes request->form creation->action. You are being passed the form in the signature of ActionForm.execute(), all you have to do is cast it to the right type:
DynaActionForm dForm = (DynaActionForm) form;
Shall i cast my business object 'sb' ? That would look like this:
DynaActionForm dSB = (DynaActionForm) sb
Or shall i look for the DynaActionForm in sb.execute() which will look
like this:
sb.execute()
{
//there must be a way to access Struts DynaForms
.
DynaActionForm dSB = (DynaActionForm) form
}
How do i get the form Objekt ?
I debugged deep into Struts sources, found a 'mapping' Object with a
'formBeans' Vector but no way to access this mapping.
Do you have a suggestion ?

How to set the selected value in an select rendered by optionsCollection
I´ve got this select rendered with data from my applicationwide
formularBean:
This renders a select like this:
Mrs.
Mr.
Dr.
.
.
The formular fields in my JSP should be prefilled with data from my person
bean ("sb")
which has a Title property, so sb.getTitle() returns 'Mr.' in this example.
Is there any chance to tell the html:select renderer "hey, if sb.getTitle()
is = 'Mr.' write
Mrs.
Mr.
Dr.
.
.
" ???
I tried this workaround:
but it rendered:
Mr.
Mrs.
Mr.
Dr.
even if Validator returns to this page because of errors.
Do you have any solutions/suggestions/articels for me to solve this problem
?
