Hello guys.
I've been struggling with Jetty 7 and its support for JSP and JSTL.
My JSP file:
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<head>
<title>blah</title>
</head>
<body>
<table id="data">
<tr class="columns">
<td>Hour</td>
<c:forEach var="campaign" items="${campaigns}">
<td>${campaign}</td>
</c:forEach>
</tr>
<c:forEach var="hour" items="${results}">
<tr>
<td class="hour">${hour.key}</td>
<c:forEach var="campaign" items="${campaigns}">
<td>${hour[campaign]}</td>
</c:forEach>
</tr>
</c:forEach>
</table>
</body>
</html>
The JSP portions above work as expected. JSTL, however, does not. The campaigns and results variables are request attributes set by a servlet.
I get the following errors:
WARN: ... compiler.TagLibraryInfoImpl: Unknown element (deferred-value) in attribute
WARN: ... compiler.TagLibraryInfoImpl: Unknown element (deferred-value) in attribute
WARN: ... compiler.TagLibraryInfoImpl: Unknown element (deferred-value) in attribute
ERROR: ... javax.servlet.ServletException: java.lang.AbstractMethodError: javax.servlet.jsp.PageContext.getELContext()Ljavax/el/ELContext;
- I am not bundling any jar files into my .war file deployed to jetty.
- The version of jetty I'm using is: jetty-hightide-7.0.1.v20091125
The classpath:

Any help would be greatly appreciated.
Thanks in advance,
Lior.
