don't understand "forEach" tag's attribute "items"

[Charles Roos]

I'm working with a jspfile which outputs data to web page, but i don't understand were the data is magically taken.
The code is such:

<%@ taglib prefix="c" uri="/JSTL_core" %>

<c:forEach items="${pagingHolder.myQueryResults}" var="decision">
	<tr>
		<td><c:out value="${decision.dateAsDateObj}" /></td>

Where is "pagingHolder.myQueryResults" defined? It seems to be a dataset, but i don't understand where is the location where this dataset is filled?
The JSP-code as you see don't import any "pagingHolder" module. Maybe in some kind of xml-file there is a connection that says that global variable "pagingHolder" refers to a Java class?

JSTL_core ? from which tld are you getting it?

Coming to your question : http://docs.oracle.com/javaee/5/tutorial/doc/bnakh.html (look for Iterator Tags)

I looked, it looks like this there:

<c:forEach var="item" items="${sessionScope.cart.items}">
    ...
    <tr>
         <td align="right" bgcolor="#ffffff">
         ${item.quantity}
    </td>
    ...
</c:forEach>

It does not explain where is defined thing called "sessionScope.cart.items" and how it is filled with data.
I think i better go through entire J2EE tutorial to get answer to myself.

It is most likely established by the page controller.
