I have an older book. It is Beginning JSP 2.0 I have tried to get the request.jsp file to work. This is on pages 42 to 44. I've installed the JSTLs to a folder I created in my /usr/local called "java". I also copied the files to the lib folder of the WEB-INF directory of the RequestHeaders directory as per the book's instructions. Here's the code for request.jsp ....
<%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c" %>
<html>
<body>
You sent the following request headers...
<p />
<table border="1">
<tr>
<th>
Header
</th>
<th>
Value
</th>
</tr>
<c: forEach var="entry" items="$(header)">
<tr>
<td>
${entry.key}
</td>
<td>
${entry.value}
</td>
</tr>
</c:forEach>
</table>
</body>
</html>
Yet, I get this in my browser window(Firefox 1.5):
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
