cannot display an arrayList in JSP
0 Answer(s)      9 months ago
Posted in : JSP-Servlet


Hello, My bean is called Zone, i got all Zones from sql Server with Hibernate. in DAO.Class: print("List zones = session.createQuery("FROM Zone").list();");

i want to send this List from a servlet to a jsp. In servlet.class print("List result = dao.getListZone();"); print("request.setAttribute("userList",result); RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/home.jsp"); dispatcher.forward(request,response);");

In Home.JSP

print("<%
String bgcolor="";
int count=0;
List viewList = new ArrayList();
Iterator  viewItr;
Iterator itr;
if(request.getAttribute("userList")!=null && request.getAttribute("userList")!="")
{
    List<Zone> userList =  (List)request.getSession().getAttribute("userList");
     itr = userList.iterator();

    while(itr.hasNext())
    {

        if(count%2==0)
        {
         bgcolor = "#C8E2D1";
        }
        else
        {

            bgcolor = "#EAF8EF";
        }

        viewList = (ArrayList)itr.next();
        int id = Integer.parseInt(viewList.get(0).toString());
        viewItr = viewList.iterator();
        %>

        <tr style="background-color:<%=bgcolor%>;">
        <%  
        while(viewItr.hasNext())
        {

            %>
            <td><%=viewItr.next()%></td>

            <%");
