在org.xml.sax.SAXParseException中安装JSTL结果：序言中不允许使用内容

在我的应用程序中，我使用JSTL。但是当我在Tomcat中部署我的应用程序时，我得到了错误。在org.xml.sax.SAXParseException中安装JSTL结果：序言中不允许使用内容

我的web.xml文件中有如下条目：

<jsp-config> 
    <taglib> 
     <taglib-uri>http://java.sun.com/jstl/core</taglib-uri> 
     <taglib-location>/WEB-INF/lib/jstl-1.2.jar</taglib-location> 
    </taglib> 
</jsp-config>

在JSP中我有以下页/标签库声明：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> 
<%@taglib uri="http://www.springframework.org/tags" prefix="spring"%> 
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%> 
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>`

这是怎么造成的异常，我该如何解决它？

您正在使用的Tomcat版本是什么？ – 2013-03-25 11:43:05

你从哪里读到你应该使用''？我希望你不要把'roseindia.net'作为一个可靠的资源？至少，将'roseindia.net'添加到您一生的Internet黑名单中。然后，请阅读我们的'[jstl]'标签wiki页面以获取正确的信息和说明。将鼠标放在问题下方显示的'[jstl]'标签上，直到出现黑框，然后单击其中的* info *链接。它应该带你到http://stackoverflow.com/tags/jstl/info。 – BalusC 2013-03-25 12:13:40

remove从web.xml中

<taglib> 
    <taglib-uri>http://java.sun.com/jstl/core</taglib-uri> 
    <taglib-location>/WEB-INF/lib/jstl-1.2.jar</taglib-location> 
</taglib>

下你不需要这个，因为的Servlet 2.0规范了。而且，taglib-location用于指定* .tld文件的路径。

它工作。谢谢。 – 2013-03-25 12:42:46

此错误消息始终是由开始元素中的无效XML内容引起的。例如，在XML元素的开头添加了一个小点“。”。

我明白了，但我的问题是我没有定义这个XML。它是jar的一部分。我仍然收到这个错误。 – 2013-03-25 12:21:07
