jsp页面显示的奇怪问题。
a.jsp中有下面一段内容：
<jsp:include page= "/bz/street/requisition/sl_frame.do ">
<jsp:param name= "num " value= " <%=num%> "/>
<jsp:param name= "name " value= " <%=name%> "/>
<jsp:param name= "jbname " value= " <%=jbname%> "/>
<jsp:param name= "jbdate " value= " <%=jbdate%> "/>
</jsp:include>
sl_frame.jsp的内容如下：
<%@ page contentType= "text/html; charset=GBK " %>
<%@ page import= "java.util.* "%>
<%
String num = (String)request.getAttribute( "num ");
String name = (String)request.getAttribute( "name ");
String jbname = (String)request.getAttribute( "jbname ");
String jbdate = (String)request.getAttribute( "jbdate ");
%>
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
</head>
<frameset id= "myframeset " rows= "30,*,0 " style= "border:none ">
<frame src= "/bz/street/requisition/toolbar.do?page=1&allpage=1 " name= "toolbar " frameborder= "0 " scrolling= "no " noresize>
<frame src= "/bz/street/requisition/sl_main.do?num= <%=num%> &name= <%=name %> &jbname= <%=jbname %> &jbdate= <%=jbdate %> " name= "main " frameborder= "0 " scrolling= "no " noresize>
<frame src= "/bz/street/requisition/sl_temp.do?num= <%=num%> &name= <%=name %> &jbname= <%=jbname %> &jbdate= <%=jbdate %> " name= "temp " frameborder= "0 " scrolling= "no " noresize>
</frameset>
<noframes>
<body bgcolor= "#FFFFFF " text= "#000000 ">
</body>
</noframes>
</html>
问题是：直接访问sl_frame.do可以正常显示，访问a.do就只显示a中的其他内容，sl_frame的内容显示不出来。
这是为什么啊？
和 <frameset> 标签有关系么？
请高手指教，谢谢！

<jsp:include page= "/bz/street/requisition/sl_frame.jsp ">
你include进来的是sl_frame.do
只能include jsp
[解决办法]
如果你想include do的后缀名可以用struts中的includeAction。
