JSTL iterate list

I have this class:

public class Orders{

    private Integer id;
    private String name;

    //getters/setters

}

In controller I pass a List<Orders> to jsp:

@RequestMapping(value = "/orders")
public ModelAndView orders(){

    List<Orders> orders = ...//get list from db

    //print list in console
    orders.forEach(e -> System.out.println(e.getId() + " - " + e.getName()));
    //print -> 1 - name1 ; 2 - name2

    return new ModelAndView("orders", "orders", orders);

}

In jsp use it like this:

${orders.size()}
<c:forEach items="${orders}" var="order">
    <c:out value="${order.getId()}"></c:out>
</c:forEach>

In browser at inspect(html code) looks like this:

"2"
<c:foreach items="[com.web.entity.Orders@21e16dd6, 
                   com.web.entity.Orders@52a33913]" var="order">
    <c:out value=""></c:out>
</c:foreach>

I tested in controller by printing list in console and everything is right.

Why in jsp is not printed?

Could you please provide more details (controller code, html page tags ...). Still I've some point to share with you :

  • Use always a toString method in your Entity/POJO.
  • Use order.id instead of order.getId()
  • Make sure you have JSTL core tag in the top of your HTML page :
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
  • Try to have a simple c:out tag:
<c:out value="${order.id}"/>
