You just have to watch out for request parameters - that info will get lost unless you put it in a cookie or a session etc.

I've hit a stumbling block and I'm not quite sure how to work around it. I've written struts apps in the past and I've taken the approach of putting everything in the ActionForm so that the jsp has a one stop shop for all it's display needs. So where I've hit an issue is when say I have jsp A that is rendered with form A. When user submits data to action A, the ActionForm pushed to execute is form A. What happens when I need to forward from action A to jsp B which is rendered with form B? I need to populate an ActionForm B to send to jsp B, but I don't have one. Is it "normal" to create a form of a different type in your Action? So essentially the code would look something like:
public void execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)
throws Exception
{
FormA inputForm = (FormA)form;
Result result = doSomeCrunchingOnDataSubmittedViaFormA(inputForm);
FormB outputForm = getInstanceOfFormB(mapping, request); //this would stash in request/session also
populateFormBWithResults(outputForm, result);
return mapping.findForward("success"); }
getInstanceOfFormB is a little hazy, but I did notice a method in RequestUtils that might help. Seems like this might be breaking some struts abstractions by knowing what form to create etc.
Is this the correct way to approach this or should I think about a redesign of my forms and actions? Thanks in advance!
