  <%
       List styles=request.getAttribute("styles");
       Iterator it=styles.iterator();
       while(it.hasNext())
       {
           out.print("<br>try: "+it.next());

You will need tom import the classes you are using in your JSP just as you would a normal Java class. Something like:

<%@ page import="java.util.*" %>

should get you up and running.
