RE: newbie:Displaying data in HTML page by prepopulating ActionForm(Help Me Plz)
Posted by Sachin Chowdhary <cs...@pisoftek.com>.
Hi Phil,
Thanks for explianing me that example that really not full info on
page you gave example of registration.
What i interpret from this is that Like:
editRegistration is only creating ActionForm then why we can not create
ActionForm manully(like when any one give some input like login in web site
and then there must be login Form on login page which will be pass to next
page suppose if it shows profile of user who logs in OK
Now when users login after validation i want to show profile of user and if
he want to edit it he can.
Now according to this code what i have to do is pass Control to first
editRegistration simply by forward to / Which will
< action path=/loginAction name="loginForm".....>
<forward name="edit" path="/editRegistration.do"/>
</action>
create ActionForm 'registrationForm' and in execute Method of
editRegistration fetch data from database and Prepopulate ActionForm and Now
page will show data in input text fields Automatically.
So why can't we simplly create an ActionForm in LoginAction.pass it to
registrationPage by request.setAttribute("",registrationForm)
What is really diff by taking one
now i will work on this code and if have any query i will ask you.Really
your expaination really help Me.
but what is diff from my code and this code and Mine if same ActionForm of
same name is created by you.
)
but now editregistration is one page and user

As Andrew has pointed out, the key idea in struts is that all user
requests should go through the controller, get dispatched to an Action
and then to the view. The form beans get created and put into the
session or request when Actions are dispatched, not when pages "load".
Struts takes a controller-centric, rather than a page-centric view. The
taglibs enable you to effectively bind HTML elements to properties of
form beans. As a concrete example, here is the sequenece of events in
the EditRegistration example described in
http://jakarta.apache.org/struts/faqs/newbie.html#prepopulate
1. The user submits a request with path /editRegistration. Since the
EditRegistration action has name="registrationForm" in its declaration,
struts creates a new RegistrationForm and puts it into the request
before calling the EditRegistration Action's execute method.
2. The EditRegistration action pre-populates the form and then forwards
to registration.jsp. HTML elements on this page are "linked" to the
form bean properties via the html tags.
3. The user edits the page and submits the form. The page posts to
/saveRegistration. This action also expects a RegistrationForm. Struts
again creates a new form, but this time there are Request parameters
that match some of the form bean properties and struts uses these to
populate the RegistrationForm passed in to SaveRegistration's execute
method. Here again the "linkage" between request parameters and form
bean properties is automatic. SaveRegistration uses these data to update
the user's information.
It may help to review the "walking tour" included in the struts-example
application.

Hi Phil,
So it is possible that if will set data in ActionForm the it will be
displayed in <html:text Automatically or i have to use value="" tag for
displaying it.
but problem is that struts is creating form of previous page and i want
to
set data in Next Form in Advance and display it automatically in
coressponding <html:text property="">
without using value="<%=name%>" .
Is it possible because struts is creating bean to pass it to Action of
that page only

Here you should use the form that struts has already created for you and
passed in via the form parameter, casting it to your form bean type:
(but problem is that form created by Struts is form from the previous page
and i want to
set data in Next Form in Advance by using this
)
SecondSimpleForm secondSimpleForm = (SecondSimpleForm) form;

The line above should be removed. Struts does this for you.

The useBean above should be removed. Struts puts the form bean in scope

Sachin,
The method described in the newbie FAQ really is the simplest way to
handle form pre-population. It's worth the effort to study the sample
app carefully and start experimenting by modifying it to get a feel for
how struts works. The problem with your code below is that you are

Here you should use the form that struts has already created for you and
passed in via the form parameter, casting it to your form bean type:
SecondSimpleForm secondSimpleForm = (SecondSimpleForm) form;
> secondSimpleForm.setFullName("Sachin Chowdhary");
>
> request.setAttribute("secondSimpleForm",secondSimpleForm);
The line above should be removed. Struts does this for you.

The useBean above should be removed. Struts puts the form bean in scope
for you.
> <bean:write name="secondSimpleForm" property="fullName"/>
> <html:text property="fullName" />
> </html:form>
> </html:html>
