Answer 1

taglib không còn được yêu cầu phải được khai báo trong web.xml, vui lòng đọc http://wiki.metawerx.net/wiki/RemovingTaglibFromWeb.xml

Bạn đang sử dụng Servlet 2.5, vì vậy các hướng dẫn nên làm việc cho bạn

Answer 2

Sửa đổi tệp web.xml của bạn để tất cả thẻ taglib được chứa trong thẻ jsp-config. ví dụ:

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

Answer 3

// trong vòng: file web.xml

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

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