在jsp页面上直接打开PDF文件

1、在不需要使用插件，直接打开通过链接方式打开

<%@ page language="java" import="java.util.*,java.io.*"pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme() + "://"    + request.getServerName() + ":" + request.getServerPort()    + path + "/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head>   <base href="<%=basePath%>"></head><%   out.clear();   out = pageContext.pushBody();   response.setContentType("application/pdf");   try {    String strPdfPath = new String("D://200701010001.PDF");    //判断该路径下的文件是否存在    File file = new File(strPdfPath);    if (file.exists()) {     DataOutputStream temps = new DataOutputStream(response       .getOutputStream());     DataInputStream in = new DataInputStream(       new FileInputStream(strPdfPath));     byte[] b = new byte[2048];     while ((in.read(b)) != -1) {      temps.write(b);      temps.flush();     }     in.close();     temps.close();    } else {     out.print(strPdfPath + " 文件不存在!");    }   } catch (Exception e) {    out.println(e.getMessage());   }%><body>   <br></body></html>

2、如果访问者的计算机上没有装acrobat reader,直接用iframe或者直接用链接打开,那就不是打开文档，而是直接下载了，为了防止下载，想像到媒体文件的播放方式，加上一些官方的docs,考虑用用object标签使用pdf插件嵌入ie中

<HTML>    <HEAD>        <META http-equiv="Content-Type" content="text/html; charset=gb2312">        <META http-equiv="Content-Style-Type" content="text/css">        <META http-equiv="Content-Script-Type" content="text/javascript">        <TITLE>Checking if Acrobat Reader installed (IE4+)...</TITLE>        <SCRIPT for="window" event="onload"<!--            document.all [                         document.all.PDFNotKnown ?

3、在网页中直接显示pdf格式的文件方便阅读。但是如果文件较大加载速度会很慢，另外如果客户端没有安装pdf阅读插件的话，也就看不了了，不过还是贴出来了，各取所需吗。（1.pdf要改成自己的pdf文件路径插入到页面文件中）
