If the first Action is getting an ActionForm with the four parameters populated, you can simply instantiate the second Action, passing it the ActionForm, and then return from the first Action the ActionForward returned by the second (or to another of the first, whatever you need).
Likewise, you can always instantiate your own ActionForm instance and pass that to the second Action, setting it up however you wish.
If I'm getting what your saying, I think it's as easy as that. But, it sounded like you are maybe grabbing the request parameters directly from the request object instead of using an ActionForm... if that's the case, there's still nothing to stop you from using an ActionForm for the second Action as input. That way you could populate the original request parameters, or put new values in their place, whatever you want.
I can tell you that adding parameters to the request object it not allowed, although I remember something about that being added in a later servlet spec. I do not know what version it IS allowed in, if that version even exists yet.

I have an Action which is usualy accessed from an html form page... It
requires 4 request parameters. I need to forward to this action from another
action but the action I'm forwarding from does not have all 4 of the reuired
request parameters. I know what the value of the parameters should be but I
cannot put them in the request scope unless I use request.setAttribute()
however the action being forwarded to is not looking for the required
parameters from the Attributes but the requestParametes.. has anyone figured
out an easy way to modify the available requestParameters before forwarding
