I want to have a shopping cart on my website, using JSP language. How do I implement this via a session array?
I need the exact code as I am just learning.

Many thanks

Problem solved, I used a bean:

package com.weselldvds;

public class cart{
  private String[] items = new String[50];
  private int[] quantities = new int[50];

  public void setItemsArray(String itemToAdd)
   if(itemToAdd == null) return;
   for(int i = 0; i < items.length; i++){
   if (items[i] == null){
   items[i] = itemToAdd; break;
  public void removeItem(int i){quantities[i] = 0;}
  public String[] getDvds(){ return items; }

  public int[] getQuantity(){ return quantities; }

This was placed in the web page:

<% String dvd = request.getParameter("dvdId");%>
<% out.println(dvd);%>

<jsp:useBean id="cart" class="com.weselldvds.cart" scope="session"/>
<jsp:setProperty name="cart" property="itemsArray" value="<%=dvd%>"/>

String[] cartItems = cart.getDvds();
for (int i = 0; i < cartItems.length; i++)
    if(cartItems[i] == null) break;
%> <br><%
