Java 找不到web.xml中的TagLib标记错误

我将按如下方式详细显示错误

 cvc-complex-type.2.4.a: Invalid content was found starting with element 'taglib'. One of '{"http://java.sun.com/xml/ns/javaee":description,"http://java.sun.com/xml/ns/javaee":display-name, "http://java.sun.com/xml/ns/javaee":icon,"http://java.sun.com/xml/ns/javaee":distributable"http:// java.sun.com/xml/ns/javaee":context-param, "http://java.sun.com/xml/ns/javaee":filter, "http://

Taglib不再需要在web.xml中声明，请阅读

---

您使用的是Servlet 2.5，因此说明应该适用于您

修改web.xml，以便所有的taglib标记都包含在jsp config标记中。i、 e:

 <jsp-config>
     <taglib>
         <taglib-uri></taglib-uri>
         <taglib-location></taglib-location>
     </taglib>
 </jsp-config>

//在：web.xml文件中

http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version=“3.1”>

/塔格里布
/WEB-INF/tlds/taglib.tld

您是否检查了dtd或xsd中元素的顺序？在意识到在许多模式中元素的顺序不是任意的（尽管它们是非常独立的）之前，我也一直在努力解决这个问题@beny:我添加了web.xml代码。请帮我一个忙。可能是taglib之前的重复，有一个标记。我正在尝试，但无法在我的答案中写入它。它没有显示任何内容。

<jsp-config>
    <taglib>
        <taglib-uri>/taglib</taglib-uri>
        <taglib-location>/WEB-INF/tlds/taglib.tld</taglib-location>
    </taglib>
</jsp-config>
