将变量放入session中去 例：session.putValue("anchor",v_key);

<%@ page contentType="text/html;charset=gb2312" %><%@ page info="database handler"%><%@ page import="java.io.*"%><%@ page import="java.util.*"%><%@ page import="java.sql.*"%><% request.setCharacterEncoding("gb2312");  String v_file_name = request.getParameter("filename"); String v_key = request.getParameter("key"); //将变量v_file_name,v_key放入session中去 session.putValue("bodyFile",v_file_name); session.putValue("anchor",v_key);  if(v_file_name!=null && v_key!=null) {  response.sendRedirect(request.getContextPath() +"/jsp/help.jsp#"+v_key);}%>

取出session变量 例：session.getValue("anchor");

<%@ page language="java" %><%@ taglib uri="/WEB-INF/tld/struts-tiles.tld" prefix="tiles" %><%@ page contentType="text/html;charset=gb2312" %><%/*get param from session*/session.getValue("bodyFile");session.getValue("anchor");%><tiles:insert template="./helpFramesetLayout.jsp"><tiles:put name="title" content="*TGPMS使用帮助*" /><tiles:put name="header" content="<%="/jsp/search.jsp"%>" direct="true" /><tiles:put name="body" content="<%="/jsp/manual/"+session.getValue("bodyFile")+"#"+session.getValue("anchor")%>" direct="true" /><tiles:put name="footer" content="<%="/jsp/footer.html"%>" direct="true" /></tiles:insert>
