If the values are not in the ActionForm, then you don't have to use the html tags. You can use standard JSP techniques to access the request and the session and write the HTML tags. Jakarta Taglibs has some very nice request and session tags that would work well in that use case.
It can still be helpful to use the html:form tag, since this handles the URL rewriting on the submit. But what's in between doesn't matter, so long as it resolves to HTML the browser understands. The html tags can also refer to other beans. So if you had your own request or session bean in play, you could use that for the bean name instead. (The current ActionForm is only the default.) It might be possible to also do something some populate from the request or the session the ActionForm's init(), but, through oversight, init is not called in 1.0 when a ActionForm is instantiated by the JSP. It is called in 1.0.1 and later. Personally, I'm not keen on populating ActionForms directly from the session or request on the JSP itself. Smacks too much of model 1. It would also make the ActionForm less portable to non-JSP environment, like Velocity. And, then, stuff can be missing, so you are into error handling, which is the controller's job.
