1) Add partialList="true" size="resultSize" to the display tag in your jsp file like so:




<display:table name="collection" cellspacing="0" cellpadding="0" requestURI="" 

    defaultsort="1" id="c" pagesize="25" partialList="true" size="resultSize" class="list" export="false">

2) Modify your action file by adding a method which gets the page number from the request




public final class DisplayTagAction extends BaseAction {



  public ActionForward execute(ActionMapping mapping, ActionForm form,

      HttpServletRequest request, HttpServletResponse response)

      throws Exception {

    if (log.isDebugEnabled()) {

      log.debug("Entering 'execute' method");

    }



  TestDataManager amgr = (TestDataManager) getBean("testDataManager");



        //get the page number from request

        int page = getPage(request);

        int size = 25;

        

        //pass in page and size

        request.setAttribute("collection", amgr.getTestData(page, size);



        //required for display tag to get the pagination to work

  request.setAttribute("resultSize", new Integer(amgr.getTestDataSizeByName("test")));



  return mapping.findForward("displayTagPage");



  }

  



    public int getPage(HttpServletRequest request){

      int page=0;

        Enumeration paramNames = request.getParameterNames();

        while (paramNames.hasMoreElements()) {

            String name = (String)paramNames.nextElement();

            if (name != null && name.startsWith("d-") && name.endsWith("-p")) {

                String pageValue = request.getParameter(name);

                if (pageValue != null) {

                    page = Integer.parseInt(pageValue)-1;

                }

            }

        }

        return page;

    }




        public List getTestData(int page, int pageSize){

  

        Query query = getSession().createQuery("from Test");



        return query.setFirstResult(page * pageSize).setMaxResults(pageSize+1).list();

       

        }
