下面是appfuse-1.8.1中的taglibs.jsp中部分内容:
<%@ taglib uri="http://jakarta.apache.org/taglibs/request-1.0" prefix="r" %>
<%@ taglib uri="http://displaytag.sf.net/el" prefix="display" %>
<%@ taglib uri="http://struts-menu.sf.net/tag-el" prefix="menu" %>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jstl/fmt" prefix="fmt" %>
<%@ taglib uri="http://java.sun.com/jstl/sql" prefix="sql" %>
<%@ taglib uri="/oscache" prefix="cache" %>
<%@ taglib uri="http://www.opensymphony.com/sitemesh/decorator" prefix="decorator"%>
<%@ taglib uri="http://www.opensymphony.com/sitemesh/page" prefix="page"%>
<%@ taglib uri="webwork" prefix="ww" %>
这些taglib为什么没有在web.xml中定义<taglib location>?
