actionForm class

[Balkan Guler <ce...@gmail.com>]

Hello.
 There is something I could not understand with actionForms.
 Suppose that I have 2 pages and a action. 
In first page I want to take student number and call the business objects in 
action to fetch the student details from database and show them in the 
second page.
 there is a studentNumberForm declared in the action-mapping block with the 
studentAction. So struts will fill the studentNumber field of the 
studentNumberForm with the first page parameter and send it to the 
studentAction.
 The question is after taking the student detail from DB where will I place 
them to show in the last page? There is only one action form...

a)
You may use hidden fields in the different pages
b)
Save the values or the complete actionForm in the session

at the whole you need a DTO(Data Transfer Object) for transferring the student fetched data to the jsp page. So you could specify an object for this purpose or use your predefine actionForm object.
 
you could use bean:write for both specified DTO and ActionForm object to display the information on the page. but if you are using ActionForm object, there's another option using form tag and the inner tags such as html:text to display its properties.

Balkan,
The values retrieved from the database don't need to be put into an 
ActionForm. Just put the collection or bean as a session or request 
attribute in your Action class, forward to your second page, and then 
retrieve the values and display them. There is no need to have an 
ActionForm associated with your second page. ActionForms are mainly used 
when you are taking form input from a page.
