JSP frameset无法引用WEB-INFO下JSP

<frameset rows="95,*,30" cols="*" frameborder="no" border="0" framespacing="0">
    <!--top样式-->
    <frame src="./top" name="topframe" scrolling="no" noresize id="topframe" title="topframe" />
    <!--contact样式-->
    <frameset id="attachucp" framespacing="0" border="0" frameborder="no" cols="194,12,*" rows="*">
        <frame scrolling="auto" noresize="" frameborder="no" name="leftFrame" src="left.html"></frame>
        <frame id="leftbar" scrolling="no" noresize="" name="switchFrame" src="swich.html"></frame>
        <frame scrolling="auto" noresize="" border="0" name="mainFrame" src="main.html"></frame>
    </frameset>
    <!--bottom样式-->
    <frame src="bottom.html" name="bottomFrame" scrolling="No" noresize="noresize" id="bottomFrame" title="bottomFrame" />
</frameset><noframes></noframes>
<!--不可以删除-->
</html>

Web.XML添加top文件的映射

 <servlet>
        <servlet-name>top</servlet-name>
        <jsp-file>/WEB-INF/jsp/top.jsp</jsp-file>
    </servlet>
    <servlet-mapping>
        <servlet-name>top</servlet-name>
        <url-pattern>/top</url-pattern>
    </servlet-mapping>
