hi,i am developing a web project.Myeclipse has already added standard.jar and jstl.jar to my project when i setup this project.
But when using jstl tags,why do i get “unkown tag”?
here is my jsp file:<%@ page language=”java” import=”java.util.*” pageEncoding=”gb2312″%>
<%@ taglib prefix=”c” uri=”http://java.sun.com/jsp/jstl/core” %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+”://”+request.getServerName()+”:”+request.getServerPort()+path+”/”;
%><!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.01 Transitional//EN”>
<html>
<head>
<base href=”<%=basePath%>”><title>My JSP ‘bookmain.jsp’ starting page</title>
<meta http-equiv=”pragma” content=”no-cache”>
<meta http-equiv=”cache-control” content=”no-cache”>
<meta http-equiv=”expires” content=”0″>
<meta http-equiv=”keywords” content=”keyword1,keyword2,keyword3″>
<meta http-equiv=”description” content=”This is my page”>
<!–
<link rel=”stylesheet” type=”text/css” href=”styles.css”>
–></head>
<body bgcolor = green>
<c:import url=”head.txt”/>
<h1 align=center>welcome</h1>
</body>
</html>thx a lot
The most likely reason is that you added JSTL 1.0 to your project but need JSTL 1.1. You can check what the correct URIs for your taglibs are by opening your standard.jar file, going into the META-INF dir, and looking in the c.tld file, look down around the 5th line or so for a <uri> tag, that is the default URI you need to use.
