Hi,
I did the following, but the results were not
displayed.
Whats wrong with my code?
>>>>>>>>>>
products is a collection of ArrayLists, every
arrayList contains
a list of ProductBeans, ProductBean has productName
and productId properties.
products are retrieved in action class and are put
into session scope:
session.setAttribute("products", products);
var productsArray = new Array();
<logic:iterate id = "aList" name = "products" indexId
= "idx">
<logic:iterate id = "ProductBean" name = "aList"
indexId = "index">
productsArray[<%=idx%>][<%=index%>]
= new Array(<bean:write name = "ProductBean"
property = "productName"/>,
<bean:write name = "ProductBean"
property = "productId"/>);
</logic:iterate>
</logic:iterate>
>>>>>>>>>>>>>
Thanks in advance.
