How to integrate jstl with tomcat 5.5?

cyan01 · Feb 15, 2005

The following question was posted on jsp forum. But I got no answer there. So I guess I would try it here.
=======================================================

I am new to JSP and am study a book "Beginning jsp 2.0". But I am having trouble in running the examples in this book.

Here is the details:

1) The example that I am running:

Code:

<%@ taglib uri="[URL unfurl="true"]http://java.sun.com/jstl/core_rt"[/URL] 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>

2) The error message I got:

org.apache.jasper.JasperException: The absolute uri:

http://java.sun.com/jstl/core_rt

org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:50)

javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

3) My guess is that I did not set up my jstl correctly. I got my jstl at here:

http://www.apache.org/dist/jakarta/taglibs/standard/binaries/

The file name is jakarta-taglibs-standard-1.1.2.zip.

After unzip it, I noticed that there are two jar files in lib dir: jstl.jar and standard.jar. The path for the example listed above is:

%CATALINA_HOME%\webapps\RequestHeaders\request.jsp
%CATALINA_HOME%\webapps\RequestHeaders\WEB-INF\lib\jstl.jar
%CATALINA_HOME%\webapps\RequestHeaders\WEB-INF\lib\standard.jar

Based on my best understanding, that's all I need to do in order to setup jstl. Have I missed something? Or am I totally wrong?

Thank you very much for reading and help!
