jsp:include and c:import combination/nesting

Hi guys, I know I've done this before with Struts.But right now, I'm working on plain Servlets and JSP(Ok, I'm using JSTL).

I have a JSP named showitems.jsp which imports two JSP's via two servlets. Those two servlets forward to another page through RequestDispatcher.

now, I include this showitem.jsp in my index.jsp

<%@ page buffer="16kb" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
 
<head>
  <jsp:include page="WEB-INF/includes/pagetitle.jsp"/>
  <jsp:include page="WEB-INF/includes/contenttype.jsp"/>
  <jsp:include page="WEB-INF/includes/nocache.jsp"/>
 
  <link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/styles/bodystyle.css" />
  <link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/styles/textstyle.css" />
  <link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/styles/tablestyle.css" />
  <link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/styles/formstyle.css" />

problem is that, the index.jsp seems to be broken. Eveything before the call to <jsp:include page="WEB-INF/includes/showitems.jsp"/> is omitted. Everything from that point on is displayed. What could be the problem with this? When I c:import with the index.jsp, everything works fine. Only that when I put those c:import tags in showitems.jsp and include that showitems.jsp in index.jsp that I'm having a problem...
