JSTL Newbie - What's causing this error?

I am a Java developer but am new to using the JSTL in JSPs.  I am working through a book and using the supplied code, but keep getting the same error.  I've googled this, but can't seem to find anything wrong with the code.

Here is a snippet of the tutorial code:

CODE

<!--Use taglib directive to include JSTL core and XML tags-->
<%@ taglib uri="http://java.sun.com/jsp/jstl/core"
    prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/xml"
    prefix="x" %>
<!--Parse newslist.xml file and store result in newslist variable in application scope-->
<c:if test="${empty applicationScope.newslist}" >
  <c:import url="http://localhost:8080/news/xml/newslist.xml" var="xml" />
  <x:parse doc="${xml}" var="newslist" scope="application" />
</c:if>  
<!--Retrieve date element value for each news element and store in tempdate variable in request scope-->
<x:forEach var="heading" select="$newslist/newslist/*">
  <c:set var="tempdate" scope="request">
    <x:out select="$heading/date"/>
  </c:set>

and here is the start of the exception:

CODE

org.apache.jasper.JasperException: 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
    org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:50)
    org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:407)

The book didn't indicate that web.xml needed to be changed.  I'm using Tomcat 5.5.  I've try putting a copy of the jstl jar in my classpath, but that didn't help.

I'm sure being new I'm missing something small.

Any ideas?


Thanks,
Tom
