Java Struts 1: forward from action to action. Passing data through ActionForms

Question

We\'ve been trying to redirect from one action to another, hoping that data would be passed between corresponding ActionForm beans. The first action receives a requ

Answer 1

Sounds like this could get messy, I'd keep this simple and use the ActionForm only to store Request data.

public class FormA extends ActionForm {
    public int intA;
    public int commonInt;
}

Once the Request has been submitted take the data out of the ActionForm and stuff it into the session somewhere, either directly, or into a data holder within the session to maintain this kind of information.

public class ActionTo extends DispatchableAction {
  public ActionForward recv(ActionMapping mapping, ActionForm form, HttpServletRequest request,HttpServletResponse response) {
    FormA form = (FormA)form;

    DataHolder dataHolder = request.getSession().getAttribute("dataHolder");
    dataHolder.setCommonInt(commonInt);
    dataHolder.setIntA(intA);

    return mapping.findForward("send");
  }
}

Ideally, if you're not heavily invested in Struts 1 I'd take a look at Struts 2.
