I'm new to struts, Do I have to create one ActionForm for each action?
If there are three buttons on one page?

No. Generally it's one ActionForm per JSP page (to match the form fields).

The number of actions depends on your design:
- One Action per JSP page that handles all actions from that page.
Easy structure to work with, but it's also easy to make one Action do
several things (not clean OO IMHO, as one object should have one
purpose).
- One action per business action.
Easy to understand, but muddles the separation between model and
controller (according to the docs, Action's are part of the controller).
- One Action overall that passes all actions to the business model.
Easy to work with, but it's dangerous: you must be really sure all input
is checked, as you pass it directly into the business layer.
