  1.   

    我现在碰到的问题是这样的 
    <%@ page language="java" pageEncoding="UTF-8"%>
    <%@ taglib prefix="s" uri="/struts-tags"%>
    <html>
    <frameset id="treeFrame" cols="160,7,*" framespacing="0" frameborder="no" border="0">
      <frame src="<s:url id ="tbDept" action="tbDept" namespace="/admin"><s:param name="targetUrl" value="/accredit/busHouseList.action"></s:param> </s:url>" name="LeftFrame" scrolling="auto" >
      <frame src="../commons/folder.jsp" name="folder" scrolling="No" noresize="noresize"/>
      <frame src="<s:url action="busHouseList" namespace="/accredit"/>" name="MainFrame" scrolling="auto" >
    </frameset>
    <noframes>
    <body>
    </body>
    </noframes>
    </html>
    我这样不能得到targetUrl的值，我的怎么改能过能，谢谢大家。
