Compilation error when trying to compile simple page

Question

Hello Everyone,
I have written a simple jsp which I intend on using as an include file. However when I try to compile the file I get the following error message (I am using Tomcat Version 4.1.30).
java.lang.NoClassDefFoundError: org/apache/jasper/
The code looks like so:
<%
  String prefValue;
  HttpSession session = request.getSession(true);
  Boolean prefValueExists = (Boolean)session.getAttribute("cookieExists");
  boolean flag = prefValueExists.booleanValue();
  if(flag == true)
    prefValue = (String)session.getAttribute("preferenceValue");
  else
  if(flag == false)
    prefValue = "0";
%>I am only just starting out so I am relatively sure that I have made a simple oversite, it would be fantastic if somebody could be so kind as to let me know what I am not doing correctly. Thanks for your time.
Kind Regards
Davo

You're using quite a lot of different classes inside your JSP. Are you sure that you've done the necessary import statements of all these classes ?
An import in JSP should be written like this :
<%@ page import = "java.util.Iterator" %>
<%@ page import = "org.gertcuppens.cluif.Film" %>
