How to update the form bean after the first submission?

Question

Hi all,
I am trying to refresh the data that have been retrieved from database to a jsp page. The first action class is retrieving data from database and display them in the jsp page. In the same jsp page I want to create a button where a user can click to refresh the data that has been update in the database side. This is done by second action class. Please let me know as this problem is hitting my head.
The first action class
public class StateResultAction extends BaseAction{
     private int year;
     private int month;
     public  ActionForward process(ActionMapping mapping,
                       ActionForm form,
                       HttpServletRequest request,
                       HttpServletResponse response) throws Exception
          String forwardPage = "";
          Vector data = null;
          Log log = getLogger();
          StateForm stateForm = ((StateForm)form);
          log.debug("in StateResultAction:"+stateForm);
          try {
               year = stateForm.getStartYear();
               month = stateForm.getStartMonth();
               StateBusLogic  busLogic = new StateBusLogic(stateForm);
               if(stateForm.getSt().startsWith("98")){
                    data = busLogic.getBalance2();
               }else{
                    data = busLogic.getBalance();
               log.debug("size of data:"+data.size());
               request.getSession().setAttribute("data", data);
          }catch (Exception e){
               log.error("Exception occur while query the balance:"+e);
               forwardPage = "error";
          request.getSession().setAttribute("startDate", fmrsForm.getStartDate());
          request.setAttribute("endDate",stateForm.getEndDate());
          request.setAttribute("st", stateForm.getSt());
                    if (stateForm.getProgNum() == 0 )
               forwardPage = "state";
          else
               forwardPage = "sub-state";
          return mapping.findForward(forwardPage);
}The second action class for Refreshing the same jsp page and getting the new data that just being entered in the database is
public class StateRefreshAction extends BaseAction {
     public ActionForward process(ActionMapping mapping, ActionForm form,
                    HttpServletRequest request, HttpServletResponse response) throws Exception {
          return mapping.findForward("state");
}
