apache - tomcat 7 taglib规范版本不一致

Question

我已将标签库包含为 -

<%@ taglib prefix="wf" uri="http://www.wrox.com/begjsp/el-functions-taglib" %>

web.xml 是

    <web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_3_0.xsd"
version="3.0">
       // some description and name


   <taglib>
    <taglib-uri>
       http://www.wrox.com/begjsp/el-functions-taglib
    </taglib-uri>
    <taglib-location>
       /WEB-INF/jsp/function-taglib.tld
    </taglib-location>
</taglib>

但是，部署此应用程序会出现以下错误日志(catalina.out)

INFO: Deploying web application archive /home/eanautg/2bkp/jsp/apache-tomcat-7.0.42/webapps/ch05.war

我尝试将架构和版本号更改为 3.0 但徒劳 -

schema = "...web-app_3_0.xsd"
version="3.0">`

我在另一个线程中读到 taglib 不应在 web.xml 中定义。那么根据新规范它应该在哪里？我错过了什么吗？请告诉我。 谢谢， 史黛西。

不确定这是否有帮助，但我在尝试查找黑板插件问题时遇到了这篇有关 Tomcat 7 taglib 声明的文章。

在 Tomcat 7 中，您的 web.xml 文件中的标记库应包含在 < jsp-config > 元素中。
