Imports in JSP should be folded (and collapsed by default, if the corresponding option is set) just like in Java code. At last those imports that are declared with a dedicated page directive:

<%@ page import="javax.naming.InitialContext" %>
<%@ page import="javax.rmi.PortableRemoteObject" %>
<%@ page import="java.io.PrintWriter" %>
<%@ page import="java.io.StringWriter" %>
<%@ page import="java.net.URLEncoder" %>
<%@ page import="java.text.DateFormat" %>
<%@ page import="java.text.SimpleDateFormat" %>
<%@ page import="java.util.Comparator" %>
<%@ page import="java.util.Date" %>
<%@ page import="java.util.Iterator" %>
<%@ page import="java.util.Set" %>
