getting size of a collection

Hi

I have collection like this.
<%    java.util.ArrayList list = new java.util.ArrayList();
list.add("First");
list.add("Second");
list.add("Third");
list.add("Fourth");
list.add("Fifth");
  pageContext.setAttribute("list", list, PageContext.PAGE_SCOPE);
 %>


Before processing this collection, I want to compare the collection item
grater than 1. how  will I do this.

Can I use like this.

<bean:size name="list" property="size" id="itemsSize" scope="session"/>

Thanks

Yes you can, but you don't have to put  " property="size'' ". The tag knows
how to get the size of an Array, a
Collection and a Map.
