hi all , i want to ask something about jsp pages 

sample jsp code  = 
**************************************************************
<%@ page import = "java.util.*" %>
<%@ page import = "MyBean" %>
<%@ page contentType="text/html;charset=ISO-8859-9" %>


<jsp:useBean id="my_bean" class="MyBean" scope="page"/>

<html>
<head>

	<%  
			ArrayList al = new ArrayList();		
			
			mybean.showData(al); // we are going to fill
ArrayList
			Iterator it = al.iterator();
			while( it.hasNext() ) {
	%>
			<%=(String)it.next()%>
	<%
		} //while
		
		al = null ; // should i  do this ?  or is it going to be
garbage collected by itself 
		it = null  ; // shoul i do this   ? 	or is it going to be
garbage collected by itself 

	%>
</head>
</html>
**************************************************************

my_bean  object will be garbage collected  because it' scope is page but
what about  ArrayList and Iterator  objects  ? 

thanks 

Regards

Altug B. Altıntas
