JSTL - iterating through lists (thanks Giblet) :)

smcelhinney

Im having trouble with lists in JSTL. I've created a rudimentary ordering system with a class hierarchy to suit. A sample hierarchy would be


Order.class
|- CustomerDetails.class
|- PersonalDetails.class
|-AddressList.class
|- Address.class
|- DeliveryAddress.class (sub-class of Address)
|- BillingAddress.class (sub-class of Address)
... etc

I've created a very simple OrderList class which just extends List (or ArrayList?). Now here's my problem. So I've created a jsp page to print out all orders from the database, Im using JDBC, with JSTL.

<jsp:useBean id="admin" class="admin.AdminBean" scope="request" />

AdminBean looks like this (just some helper utilities):

public class AdminBean implements Serializable {
    
    private List orderList;
    
   /** Creates a new instance of AdminBean */
    public AdminBean() {
           this.orderList = getAllOrders();
    }
    
    public List getAllOrders(){
        return new ResultSets().getAllOrders();
    }
    
    public Order getOrder(int id){
        return new ResultSets().getOrder(id);
    }
}

So you would think that by doing:

<c:forEach items="${admin.orderList}" var="order">
</c:forEach>

I could access the elements of this list (objects of class Order), and display the properties of them .

But, I cant

any thoughts? Do I need to use a ListIterator class?

I'm surprised it has not thrown an error around 'admin.orderList"

what this is saying is that using http://java.sun.com/j2se/1.4.2/docs/api/java/beans/Introspector.html

it looks for a method called 'getOrderList'

you have getAllOrders() .. so rename this or use
<c:forEach items="${admin.allOrders}" var="order">

Grr

Yeah you should be using it like this

type varName

public type getVarName()
{
return type;
}

in your class.
