taglib to scriptlet attempt

[Ed Gretson]

I have a taglib here that works great.

<c:forEach var="customer" items="${requestScope.customers}">
<a href="controller?action=displaycustomer&id=${customer.id}">${customer.id}</a>
${customer.lastName}
</c:forEach>

Now I would like to eliminate the taglibs and do it with scriptlet:

<% for(int i = 0;i < customers;i++)
{
%>
<a href="controller?action=displaycustomer&id=customer.id">customer.id</a>
customer.lastName} <%
} %>

Please advise because it keeps giving me variable errors on my jsp after I try the scriplet attempt.

What is 'customers' in this line?

 
<% for(int i = 0;i < customers;i++)

Umm, isn't that heading in the wrong direction?

Just to show how ugly it can be in scriptlet code:

<%@ page import="java.util.*, com.mypackage.Customer" %>
<%
List customerList = (List)request.getAttribute("customers");
for(Iterator it = customerList.iterator(); it.hasNext(); ){
  Customer customer = (Customer)it.next();
  %>
  <a href="controller?action=displayCustomer&id=<%= customer.getId() %>"><%= customer.getId() %></a> <%= customer.getLastName() %>
  <% } %>

Thats as nice as I can make it.
I assumed that you were iterating over a list of Customer objects.
It means you have to import both the java.util and your Customer objects into the page.
If its an array, then cast it to an array (Customer[] I guess), and use standard loop for an array.

Replaced the forEach tag with a for loop using an Iterator.
Replaced ${expr} with <%= expr %>

All in all, the JSTL looks so much nicer don't you think?
