How to do Pagination in struts application????

Question

My struts application lists the records from database using iterator.
I use ArrayList in Action class and i access the list in JSP through by setting request variable in action class.But if i have 10 fields which are multi line format such as address.I need to restrict records 4 per page.how to do that??
I am stuck in pagination of struts.

Answer 1

Use dispatch action.Here i am displaying only 2 records per page because my appln required 10 fields you can extend it to any count.You can use this..
public class FeedListAction extends DispatchAction {
     public ActionForward list(ActionMapping mapping,
                                ActionForm form,
                                HttpServletRequest request,
                                HttpServletResponse response)
             throws IOException {
          //List method is called first when we want to list our records.
                                  FeedForm frm = (FeedForm)form;
                                  ArrayList feedlist = new ArrayList();
          //session is used to know where are we..
                                  HttpSession ses = request.getSession(true);
          // two parameters which will be used to limit the records for perticular page.
                                  String s = "0";
                                  String e ="2";
          //call the method which will be used to display the records..
                                  feedlist = frm.getEmployees(Integer.parseInt(s),Integer.parseInt(e));
          //set the list so that jsp page will use to display it.
                                  request.setAttribute("list", feedlist);
          // set the attributes so that they are used while navigation and
          // these attributes wiil be used by the  other methods of Dispatch action.
                                  ses.setAttribute("s", s);
                                  ses.setAttribute("e", e);
          //Find the success page.
                                  return mapping.findForward(success);
          //end of List method
     public ActionForward next(ActionMapping mapping,
                                ActionForm form,
                                HttpServletRequest request,
                                HttpServletResponse response)
              throws IOException {
                                  //here add code for session.          
                                int en =0;
                                int st=0;
                                st = Integer.valueOf( s ).intValue();
                                  en = Integer.valueOf( e ).intValue();
// to know whether next has exceeded the recordset limit we need to take number of rows
// which can accessed through nrows function.
                                  int nrows = frm.rows();
                                  if(st==(nrows-2)){
                                       st = nrows-2;
                                  }else{
                       st=st+2;en=2;                                      
  //go for setting values in your module (which will interact with dadtabase to fetch records).                                           ses.setAttribute("s",Integer.toString(st));
//then set session attribute.                                  
                                  return mapping.findForward(success);
       //end of next method.     
     }
