Not sure I fully understand but here goes...
When form.jsp starts generating the HTML for the form, it will look for
an ActionForm from which it can get default values. The name it will
use to look for this bean is defined in the struts-config.xml under the
Action to which you will be submitting the form. So the ActionForm name
is associated with the Action that receives it rather than the JSP that
generates it. So the fact that the JSP that generates it is wrapped
inside a frame isn't really an issue.
There are at least two other possible problems, though:
1) If you want the previous Action to preload the ActionForm with
some information (from a database, for example) you can do
this by making your own ActionForm bean, filling it in, and
then saving it in the session scope under the name which is
declared in the Action that will receive it. It will then be
found automatically when form.jsp generates the HTML.
2) If you choose to automatically validate the ActionForm, you
need to specify the "input" page so that Struts can
automatically send you back there in case of an error. I don't
have experience with this but you should be able to specify
your frame.jsp file as the input source. When it then
renders form.jsp within, this inner page will still find the
ActionForm in the context if it were the highest level page.
Does that help?
