無法在web.xml或jar文件中解析http://displaytag.sf.net

嘗試從數據庫加載時，在eclipse中出現以下錯誤。無法在web.xml或jar文件中解析http://displaytag.sf.net

org.apache.jasper.JasperException: The absolute uri: http://displaytag.sf.net cannot be resolved in either web.xml or the jar files

請在這裏找到web.xml文件。

，並查看頁面：

<html>

<a href="indexpage.htm">Click here for Home</a> 

<h2 align="center">View Information</h2>

    <display:column property="name" title="Employee Name" 
     href="editdata.htm" paramId="id" paramProperty="emp_id"

    <display:setProperty name="paging.banner.placement" value="bottom" />

我是否需要申報<%@ taglib uri="http://displaytag.sf.net" prefix="display"%>與web.xml中？

我已經通過 Display tag : The absolute uri: http://displaytag.sf.net cannot be 但沒有解決。

是否確定由標籤罐子真的是在你的類路徑中？ –

@AleksanderBlomskøld：我很抱歉，這是缺少....添加displaytag-1.2.jar ..現在工作。一旦你發佈答案，你會接受。 – NaaN

你必須確保displaytag jar包在你的類路徑中！

將它添加到類路徑後，得到了同樣的錯誤不過我們去的錯誤

org.apache.jasper.JasperException: The absolute uri: http://displaytag.sf.net cannot be resolved in either web.xml or the jar files deployed with this application

當我們把它添加到部署大會錯誤得到解決
