Jsp will not display table with contents

Question

I am working on a project with java servlets and JSP.

I have a java class that generates me a list of products, of type List<Product> and I saved the list in variable Products.

Ex:  List<Product> products = ProductIO.selectProducts();

To access the name description of each list I use. (print them to screen)

System.out.println(products.get(i).getDescription());

Okay! Now here comes the problem, I want to generate a table and place all items descriptions in there, However I get a blank table and I assume is bad syntax.

Here is my products.jsp code.

<!DOCTYPE html>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
    <meta charset="utf-8">
    <title>Murach's Java Servlets and JSP</title>
    <link rel="stylesheet" href="styles/main.css" type="text/css"/>
</head>
<body>
<h1>CD list</h1>
<table>
    <tr>
        <th>Description</th>
        <th>&nbsp;</th>
    </tr>        
    <c:forEach var="product" items="${products}" varStatus ="i">
    <tr>
        <td><c:out value='${product.get(i).getDescription}' /></td>
    </tr>
    </c:forEach>
</table>
</body>
</html>

`System.out.println(products.get(i).getDescription());` is this gives you anything on console? — Rishal, Oct 03 '16 at 15:42
I would think you need to do either `${product.get(i).getDescription()}` or `${product.get(i).description}` rather than what you have there. — Zircon, Oct 03 '16 at 15:43
@Rishaldevsingh , Yeah, it prints out the name of CD fine inside the servlet. — Gui Costa, Oct 03 '16 at 15:46
I think you trying to iterate over var "product" instead of list "products", you can either try ${products.get(i).getDescription()} or ${product.description}. — Foxy, Oct 03 '16 at 15:48
@Rishaldevsingh I tried it, my table is empty. I only have on browser CD list Description — Gui Costa, Oct 03 '16 at 16:00
` ` assuming you have `description` as your variable in the `Product` class,Try this. Also let usknow how you are passing the data from your `java class` to `jsp`. — Rishal, Oct 03 '16 at 16:09
@Rishaldevsingh This is inside my servlet .HttpSession s=request.getSession(); s.setAttribute("product",products); — Gui Costa, Oct 03 '16 at 16:46

EDITED

p_IO.selectProducts() may be a List<Product> so you don't need to extract list within forEach. Try this:

....
<c:forEach items="${p_IO.selectProducts()}" var="product" >
    <tr>
        <td><c:out value='${product.description}' /></td>
    </tr>
</c:forEach>
....

Unfortunately I still get empty. I tried that way and ${product.get(i).getDescription()} or ${product.get(i).description}. – Gui Costa Oct 03 '16 at 15:51
have you tried `${products}` or `${products.size()}` or `out.print(request.getAttribute("products"))` ? – auntyellow Oct 04 '16 at 00:03
Thank you auntyellow! After all day battling with this. Your exact code above worked! – Gui Costa Oct 04 '16 at 02:10
