Subject: java.util.Vector cannot be cast to entity bean

I am storing data in a servlet and passing it onto a jsp to display as-

servlet -

try{
                 //call the allbales method
                 baleent=baleBeanRemote.findAllBales();
                  HttpSession session = request.getSession();
                  session.setAttribute("baleent",baleent);
                  RequestDispatcher dispatcher = getServletContext()
                                               .getRequestDispatcher("/Viewdisplay.jsp");
                                               dispatcher.forward(request, response);
                                 //forward data to the DiscountItemsj.jsp to present
                                //it to user
                                dispatcher.forward(request, response);
             }
            catch(Exception ex){
   System.err.println("Can not show the all BALES page");
   }
            }


jsp -

<jsp:useBean id="baleent" scope="session" class="entityJB.Baleent" />


I get the following error when I ran the it -
