Why not add another <action> mapping in between Page1Action and page2?
Something like this:
page1.jsp -- submit --> Page1Action -- fwd --> PrepPage2 --> page2.jsp
Then, set the "name" for Page1Action to "Page1Form" and the "name" for
PrepPage2 to "Page2Form". Then, you can use the form that gets provided
by Struts directly in your execute method.

If you call the constructor for Page2Form, you /will/ get a new object.
Struts has nothing to do with this. You must be doing something else in
your action to put this object into session or request scope.

If page2.jsp contains a form, then it is perfectly natural to use an
ActionForm to shuttle data from the action to the page.
