        <meta http-equiv="pragma" content="no-cache">
        <meta http-equiv="cache-control" content="no-cache">
        <meta http-equiv="expires" content="0">    
        <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
        <meta http-equiv="description" content="This is my page">
        <!--
        <link rel="stylesheet" type="text/css" href="styles.css">

  </head>
  
  <body>
    This is my JSP page. <br>
    <form action="out.jsp" method="post">
        name : <input type="text" name="tname"><br>
        <input type="submit">

<%@ page contentType="text/html;charset=UTF-8" language="java" %> 
<%@ page language="java" import="java.util.*"%>
<%@ page language="java" import="com.lowagie.text.*,com.lowagie.text.pdf.*"%>
<%@ page language="java" import="java.io.*"%>
<%
        response.reset();
        //创建文件头信息
        response.setContentType("application/x-msdownload");  
        response.setHeader("Content-Disposition",   "attachment;   filename="+new String(("hello"+request.getParameter("tname")+".pdf").getBytes(),"iso8859-1"));  
        //文件输出流
        ServletOutputStream sos = response.getOutputStream();  
        Document doc = new Document();
        PdfWriter.getInstance(doc, sos);  
        doc.open();  
        doc.add(new Paragraph("Hello "+request.getParameter("tname")+" !"));  
        doc.close();
        //关闭
        sos.flush();
        sos.close();
        out.clear();
        out = pageContext.pushBody();
 %>
