So you're trying to pre-populate a form? ... which you're just about to
show a user?
link -> action f-> JSP (f-> == forward)
- link points to action
- action populates form
- action forwards control to JSP
Is this your scenario?
You need to:
- build a form-bean (by extending ActionForm) or use a
DynaActionForm (or similar)
- associate the form-bean with the action (so Struts will create it)
- extend Action (or one of it's descendants) and code the "execute"
method so that it pre-populates your bean and then forwards to the JSP page.
Once you have done this, your action is passed an instance of the
form-bean which should be available to the JSP page. You just populate
it and forward control. Be aware though :-) that if you then send the
user to a "view" page (to show what their edits were, perhaps), you'll
have to be looking in the same scope for the form-bean, or you're not
gonna find it ;-)
Ex:
<action path="/editUser" ... scope="request" ... />
<action path="/viewUser" ... scope="request" ... />
The default scope is session. If that's where you want the form kept
you don't have to specify it.
