um.. i'm pretty sure that it doesn't matter.
the system garbage collector MAY reap memory for objects that are set to
null.
remember once the service method executes all the method variables ( al & it
) go out of scope and are elegible for gc.
if you had static or class level members using <%! %> tags then they would
not be gc until their references were nullafied.
hope this helps.
warren.

Subject: memory allocation
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
