写了个测试页面:
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<%@ taglib uri="http://displaytag.sf.net/el" prefix="display"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
%>
<%
List<String> test=new ArrayList(1);
test.add("a");
request.setAttribute("test", test);
%>

运行就会报SEVERE: Servlet.service() for servlet jsp threw exception
java.lang.ClassNotFoundException: org.apache.commons.lang.UnhandledException这个错
删掉display的引用或者删掉display:table标签就不会报错了，这是哪里错了到底
