Re: Action BEFORE a page is constructed?
One way to populate a form before it is used (say you want to load user information for editing) is to create an action called preloadUserAction. In the config file create an action mapping such as The userForm is passed into the preload action. This populates the form and then forwards onto the page that will use that form. The example application uses the same technique but is a bit more complex because the action is dual use: see EditSubscriptionAction.

RE RE: Action BEFORE a page is constructed?
Hello,
I did not get it.
Rather than directly forwarding to /order I now forward to /prepareorder. Is
this right?
However, it looks that I still have an error, because the forwarding from
one action
to another does not work - and even give any helping error message:
After the jsp in action tag 1 is submitting its control to the action
defined in
action tag one it should call the action in action tag 2. But nothing
happens.
Can you help me?

If you want to do some preparations before you create the form you can make
a new actionclass without a form class.
Now when you want to call you new screen you first call this action wich is
not linked to a form, when this action succeeds, you can call you jsp page,
wich has a form in it. To fill this form you make an instance of this forms
form class and fill it using the set methods. After this you put this form
into the session scope. Like this
request.getSession().setAttribute("orderForm",orderForm);
Now you form will be filled in when it is shown on the screen.
