struts的标签

<%@ taglib uri="/struts-tags" prefix="s"%>

<%@ taglib uri="/WEB-INF/tld/struts-bean.tld" prefix="bean" %>

<%@ taglib uri="/WEB-INF/tld/struts-html.tld" prefix="html" %>

<%@ taglib uri="/WEB-INF/tld/valuelist.tld" prefix="vlh"%>

<%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c" %>(貌似自定义标签其实和这句差不多<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>)
