爲什麼我不能在我的jsp中使用核心taglib？

當我將taglib包含在我的jsp中時遇到了問題。當我啓動tomcat時，出現以下錯誤報告。爲什麼我不能在我的jsp中使用核心taglib？

的特定線，使得它的工作，不工作去爲這個

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

完整代碼包含下面。

我知道有很多類似的問題，但是我發現的所有問題都已通過將jstl依賴項添加到pom文件中解決。我已經這樣做了，但仍然面臨同樣的問題。

的index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" 
    pageEncoding="UTF-8"%> 
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 
<title>Insert title here</title> 
</head> 
<body> 
<h1>Testing</h1> 
<c:redirect url="/home.jsp" /> 
</body> 
</html>

的pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

檢查第一個答案在這裏 - http://stackoverflow.com/questions/4928271/jstl-1-2-the-absolute-uri-http-java-sun-com-jstl-core-cannot-be-resolved tell如果它有幫助.. –

嘗試增加以下Maven依賴於你的pom.xml：

<!-- standard.jar --> 
<dependency> 
    <groupId>taglibs</groupId> 
    <artifactId>standard</artifactId> 
    <version>1.1.2</version> 
</dependency> 

<!-- JSTL --> 
<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>jstl</artifactId> 
    <version>1.1.2</version> 
</dependency>

我以前添加過這些。但添加這些後，我做了一個右鍵單擊 - > Maven - >下載源。似乎已經完成了這個訣竅。 – James
