获得阅览器信息，提示util can not resolved（急求）
我在apache上看代码，snoop.jsp这个例子程序
<body bgcolor= "white ">
<h1> Request Information </h1>
<font size= "4 ">
JSP Request Method: <% out.print(util.HTMLFilter.filter(request.getMethod())); %>
<br>
Request URI: <%= request.getRequestURI() %>
<br>
Request Protocol: <%= request.getProtocol() %>
<br>
Servlet path: <%= request.getServletPath() %>
<br>
Path info: <% out.print(util.HTMLFilter.filter(request.getPathInfo())); %>
<br>
Query string: <% out.print(util.HTMLFilter.filter(request.getQueryString())); %>
<br>
Content length: <%= request.getContentLength() %>
<br>
Content type: <% out.print(util.HTMLFilter.filter(request.getContentType())); %>
<br>
Server name: <%= request.getServerName() %>
<br>
Server port: <%= request.getServerPort() %>
<br>
Remote user: <%= request.getRemoteUser() %>
<br>
Remote address: <%= request.getRemoteAddr() %>
<br>
Remote host: <%= request.getRemoteHost() %>
<br>
Authorization scheme: <%= request.getAuthType() %>
<br>
Locale: <%= request.getLocale() %>
<hr>
The browser you are using is <% out.print(util.HTMLFilter.filter(request.getHeader( "User-Agent "))); %>
<hr>
</font>
</body>
我仿照这个在我的登陆页面做个输出，
<%
System.out.println( "Remote address: "+request.getRemoteAddr());
System.out.println( "Remote host: "+request.getRemoteHost());
System.out.println( "Locale: "+request.getLocale());
System.out.println( "The browser you are using is ");
out.print(util.HTMLFilter.filter(request.getHeader( "User-Agent ")));
%>
但是页面提示util can not resolved，我不明白这个对象是什么类型的，还是我少了什么开发包 ？？

util 写出这个包的完整路径应该就没问题了！！！
