尝试从数据库加载时，我在Eclipse中遇到以下错误。
org.apache.jasper.JasperException: The absolute uri: http://displaytag.sf.net cannot be resolved in either web.xml or the jar files
在此处完成堆栈跟踪：
SEVERE: Servlet.service() for servlet jsp threw exception
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

请在此处找到web.xml。

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>

和查看页面：
<%@ taglib uri="http://displaytag.sf.net" prefix="display"%>
<html>
<h2>Welcome</h2>
<a href="indexpage.htm">Click here for Home</a>
<h2 align="center">View Information</h2>
<body></body><center>
<display:table cellpadding="2" cellspacing="20" id="employee" name="employee" pagesize="10"
export="false" requestURI="displayEmployee.htm">
<display:column property="emp_id" title="Employee Id" sortable="true" />
<display:column property="name" title="Employee Name"
href="editdata.htm" paramId="id" paramProperty="emp_id"
sortable="true" />
<display:column property="address" title="Address" sortable="true" />
<display:column property="salary" title="Salary" sortable="true" />
<display:column value="Delete" href="deletedata.htm" paramId="id"
paramProperty="emp_id" title="Delete" sortable="true" />
<display:setProperty name="paging.banner.placement" value="bottom" />
</display:table>
</center>
</body>
</html>
我是否需要使用web.xml声明
<%@ taglib uri="http://displaytag.sf.net" prefix="display"%>？我走了
Display tag : The absolute uri: http://displaytag.sf.net cannot be
但没有解决。
最佳答案
您必须确保displaytag jar位于您的类路径中！
