I am writing a web application that runs within an embedded Jetty instance.

When I attempt to execute a JSTL statement, I receive the following exception:

org.apache.jasper.JasperException: /index.jsp(1,63) PWC6188: The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application

I have the following jars on the classpath

ant-1.6.5.jar
ant-1.7.1.jar
ant-launcher-1.7.1.jar
core-3.1.1.jar
jetty-6.1.22.jar
jetty-util-6.1.22.jar
jsp-2.1-6.1.14.jar
jsp-api-2.1.jar
jstl-1.2.jar
servlet-api-2.5-20081211.jar
servlet-api-2.5-6.1.14.jar
standard-1.1.2.jar

My web.xml looks like this:

<?xml version="1.0" encoding="ISO-8859-1"?>  
    <web-app xmlns="http://java.sun.com/xml/ns/j2ee"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee h77p://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"  
    version="2.4">  
    <display-name>test</display-name>  
</web-app>

My code looks like this:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>  
<html>  
    <body>  
        <h2>Hello World!</h2>  
        <%= new java.util.Date() %><br/>  
        ${1+2}<br/>  
        <c:out var="${5+9}"/><br/>  
    </body>  
</html>

I started my embedded Jetty server like this:

Server server = new Server(80);  
WebAppContext context = new WebAppContext("pig-1.0-SNAPSHOT.war","/");
server.addHandler(context);
server.start();

I spent the past two days experimenting with various combinations of jar files, web.xml configurations, and tag library declarations, but to no avail.

How can I get an embedded Jetty server up and running with full JSTL support?
