Servlet - JSP Programming

[krishkill]

I have a code in servlet like this
ArrayList <Integer> total = new ArrayList <Integer>();

session.setAttribute("efg",total);


RequestDispatcher rd;
rd = request.getRequestDispatcher("/checkout.jsp");
rd.forward(request,response);

to print the values in ArrayList total, I did this in my JSP

<%ArrayList<Integer> s3= new ArrayList<Integer>(); %>
<% s3 = (ArrayList)session.getAttribute("efg"); %>
<% for(int i:s3){
//int d3=Integer.parseInt(i);
out.println(i);}%>

But nothing is being printed in my page. please help me if i did anything wrong in the syntax.

[al_Marshy_1981]

nope.. donno

out of curiousity what is an ArrayList?

[krishkill]

Arraylist is meant for collection of objects.. its similar to an array but with ease, it has inbuilt methods and unspecified length.. like it can grow its size by adding.

[al_Marshy_1981]

ok I was just wondering why you have what seem to be ASP % code inserted into a declaration of an ArrayList, which either I have never seen before or you have found some ingenious way of integrated both that I have yet to discover.

its called scriplet.. it is used to write java code in a jsp page..

You've given your array list object three different names...total, efg, and s3. That won't solve your problem, but it would confuse the hell out of me trying to debug this.
:)

Are you sure your array list actually has values in it?
Just prior to the session.addAttribute print them all out.
