I try to run my jsp code on Tomcat v7 server but it failed.
org.apache.jasper.JasperException: /jsp/Checkout.jspx (line: 32, column: 51) The attribute prefix fn does not correspond to any imported tag library
But my jsp code had fn definition
xmlns:fn="http://java.sun.com/jsp/jstl/functions"

How should I solve this problem?
I loaded the project again in eclipse, I just changed the code in web.xml.
servlet-mapping>
<servlet-name>ShopServlet</servlet-name>
<url-pattern>/ShopServlet</url-pattern>
</servlet-mapping>
URL is : localhost:8080/eshopx/ShopServlet
The error message changed
description The requested resource is not available.

You need to use the taglib declaration in your jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions"
prefix="fn" %>
